5 Introduction Application Description The intent of this document is to inform users on the general workflow from capturing point cloud data to diagramming the scene. Required Materials The materials required depend on the current step in the process. During the processing of the scene, the following materials needed are: Personal protective equipment FARO Focus 3D SD card Tripod with bubble level Targets (i.e. printed checkerboards and/or reference spheres) Tape measure and/or reference scale (Optional) Laptop with licensed copy of SCENE The materials required during the analysis of the data include: SD card Laptop with a licensed copy of SCENE Laptop with a licensed copy of Crime/Crash Zone Page 5 of 54

6 Step 1 Focus 3D Setup Begin by setting up a project for the scene to scan on the scanner: 1) Power on the Focus 3D 2) Press 3) Press Projects, 4) Press to create a new project a) Press Project Name and enter an appropriate name for the project. Note: This must begin with a letter and cannot include spaces b) Verify Parent Project is set to No Parent Project c) Press File Base Name and enter an appropriate prefix for each scan file s name and end with _Scan_. Note: This cannot include spaces. d) Adjust the Initial Scan No. as needed 5) Return to the Home screen ( ) 6) (optional) Set the reference height for the scan project: a) Press b) Press Sensors, c) Press Altimeter, d) Press e) Return to the Home screen ( ) 7) Press 8) Press Selected Profile 9) Select the profile needed for the project Before heading to the scene, make sure the SD card is in the scanner! Page 6 of 54

7 Plan the Scan It is recommended to determine the general locations for scanning prior to the first scan. Scan locations are subjective and often based on one or more of the following criteria: Captures the needed data and is within the line of sight of the scanning device Maximizes the amount of the scene/evidence that will be captured Provides a stable base and space for the scanner and tripod Avoids direct sunlight as this can affect scanning range; shade the scanner if possible Avoids placement that will adversely affect the exposure setting of the camera (when color is used) Facilitates a virtual walkthrough of the scene in WebShare Note: Areas requiring fine detail or with small objects of interest should be scanned at either higher resolutions or with the scanner placed closer to area of interest. Page 7 of 54

8 Step 2 Target Placement For Target placement, identify areas common to two or more scan positions which do not interfere with evidence collection. There is no set method for target arrangement, however in some cases the availability of space and/or stable surfacing for the scanner and tripod may limit the location for targets. Experience will dictate arrangements over time; however, the following tips for target placement will help automate the registration process. MUV3 Mix it Up o Feel free to mix targets (various sized spheres and/or checkerboards) o If using various sized spheres, there needs to be enough distinction between the spheres diameters for the software to correctly associate the correct diameter. Unique Patterns o Targets need to vary in height and distance from each other to create unique patterns that the software can successfully match between scans Visibility o Targets must be positioned where they can be seen from more than one (1) scan position (overlapping areas) o Where possible, the last scan position should overlap the same targets used in the first scan. In this situation, some scan projects may require up to nine (9) targets. Rule of Three s (3) o Try to have 3 visible targets between the scans to combine o Place the targets neither closer than 3ft to the scanner nor 3ft to another target Examples: Note: Scanner and targets are not to scale in the following images Page 8 of 54

9 Figure 1: Sample intersection layout based on 1/4 (7.5) resolution with 4x quality and using a maximum target placement of 60ft/20yds/18m away from the scanner. Figure 2: Sample highway layout based on 1/4 (7.5) resolution with 4x quality and using a maximum target placement of 60ft/20yds/18m away from the scanner. Figure 3: Sample indoor layout Page 9 of 54

10 Target Specific Tips Checkerboards Print with a laser printer on letter sized paper Spheres Place such that their view is completely unobstructed from each scan position where the sphere is used Both Place such that the scan neither begins nor ends on them. This is referred to as splitting the sphere or splitting the checkerboard accordingly. Mounting Securely affix targets such that they do not move during scanning. Wind and vibrations can alter the location of targets during scanning and adversely affect registration. Target Placement Distance Guidelines If a target is placed too far from the scanner, there will not be enough scan points to adequately define the target in SCENE. Ideal distances from the scanner to the target largely depend on the resolution use. A higher resolution (example: 1/1) results in more points captured whereas a lower resolution (example: 1/32) results in less points captured. Testing in different environments can provide a general guideline to follow, however, certain conditions could still result in targets that are not identified by SCENE. The following table can be used as a general guideline for the maximum distance the standard 70mm spheres can be placed from the scanner when scanning at a 4x quality: Resolution MPts Distance Time (s)* 1/ = 15ft / 5yds / 4.5m 00:00:43 1/ = 25ft / 8yds / 7.5m 00:01:04 1/ = 32ft / 11yds / 10m 00:01:23 1/ = 39ft / 13yds / 12m 00:02:47 1/ = 63ft / 21yds / 19m 00:04:04 1/ = 129ft / 43yds / 39m 00:14:48 1/ = 232ft / 77yds / 70.5m 00:57:45 *Times based on a full scan without color When using larger spheres, scale the values accordingly. Note: Further testing may result in greater range at various resolutions. Environmental conditions may reduce the stated range! Page 10 of 54

11 Step 3 Reference Measurement Qualification of the measurements within the data captured must be determined using an acceptable form for comparison. Some methods for qualifying the data include: Using an approved measuring device (i.e. tape measure), measure a fixed object(s) original to the scene that will be scanned and record its size. Include in the scan(s) a reference scale. The placement and scanned resolution chosen must allow for selection within the resulting scanned data. Step 4 Scanning Once the scanning positions are identified and the targets are in position, it is time to begin the scan: 1) Place the scanner on a secure foundation that is free from movement and vibration 2) Use either the bubble level on the tripod or in the scanner s interface to level the scanner to an inclination less than 5. If there is a need to scan inverted or at 45 angles or greater to the horizontal, a special bracket must be manufactured to securely mount the scanner. 3) Adjust the scanner s head such that primary objects of interest and targets do not lie at the 0 /360 or 270 scanning positions 4) If qualifying the data with a reference scale, place the scale in a secure and appropriate location for inclusion in the scan 5) With the Focus 3D powered on and at the Home screen of the scanner s interface, press a) To access the Home screen, press Page 11 of 54

12 It is recommended the operator move to a position not within the line of sight of the Focus 3D to avoid inclusion in the scan data. During the scan, the scanner s lights will blink red while the laser is emitting from the scanner. Once the laser has completed its portion of the scan and, if the color option was chosen, the scanner will take the pictures of the scanned area. During this time, the scanner s lights will blink blue. Once the scan is complete, the scanner s light will remain a solid blue and a preview of the scan will appear on the screen. 6) For multiple scans, move the scanner to its next position; add/remove targets as needed. Repeat steps 1) through 5), including 4) where appropriate, until scans of all desired locations have been captured 7) Remove the SD card from the scanner as it is needed for the registration process 8) (Optional) Verify that the data captured is sufficient prior to demobilizing. Using the laptop licensed for SCENE: a) Refer to Auto-Importing (p.5) b) Right-click each scan and select View > Planar view c) Review the results To power the scanner off, press the power button on the scanner. Step 5 Evidence Management A copy of the SD card must be stored to maintain the security and integrity of the originally captured data. Use the approved method for documenting and storing original copies of evidence. Page 12 of 54

13 Step 6 Registration Registration is the process of arranging the scans into a single cohesive coordinate system. Use the computer/laptop that is licensed for the SCENE program to register the data. Auto-Importing To automatically register data located on the SD card: 1) While SCENE is running, insert the SD card into the SD card slot of the computer 2) When prompted to start the automatic transfer, click [Yes] Figure 4: Automatic data transfer option 3) Wait for the computer to finish importing, then open the project once it appears in the Project Selector by selecting it then clicking Page 13 of 54

48 Appendix B: Viewing Controls Working with three-dimensional data requires manipulation of views in order to better work with the data. Isolating Points in the Point Cloud Many points are captured during scanning and may cause confusion when drawing elements for diagrams. Simplify the drawing process by isolating the area of the point cloud that is being worked on and hide all other points until they are needed. To do this: 1) In the Point Cloud window, use navigational tools to choose a view that allows optimal selection of the area of interest 2) Click 3) Select the needed method of removing points a) Keep Window Drag a window around a section of points to display on the screen b) Hide Window Drag a window around a section of points not to display on the screen 4) Draw a rectangle around the points to show/hide Repeat these steps as needed to show/hide more points! Show All Points in the Point Cloud To show all available points in the point cloud: 1) In the Point Cloud window, click 2) Select Show All Points Page 48 of 54

49 Hide All Points in the Point Cloud To hide all points in the point cloud: 3) In the Point Cloud window, click 4) Select Turn Points OFF Example: Removing the Ceiling in a Room 1) In the Point Cloud window, choose one of the side views 2) Click 3) Select Hide Window 4) Draw a rectangle around the ceiling Figure 58: Rectangle drawn around the ceiling Hide Points in a Cloud based on Color To hide points based on color: 1) In the Point Cloud window, click 2) Select Hide Colors, 3) Select an area of points with the cursor to base hiding o If the too much information is removed, click Display Tool then Undo Last Page 49 of 54

Maximize Viewing Equal Sharing of the Screen (Single Monitor Systems) When working with point clouds in CZ, it is best to view both CZ and the Point Cloud tool at the same time. If two (2) monitors are available, this can be done by placing CZ full screen on the left monitor and CZ Point Tool full screen on the right. When dual monitors are not an option: 1) Move the mouse to the title bar of CZ 2) Click and hold the left mouse button 3) Drag the cursor to the left edge of the computer s screen until a ripple effect occurs at the cursor Figure 60: Ripple effect appears 4) 5) 6) 7) Release the cursor Move the mouse to the title bar of CZ Point Cloud Click and hold the left mouse button Drag the cursor to the right edge of the computer s screen until a ripple effect occurs at the cursor 8) Release the cursor Page 50 of 54

51 Maximize Viewing Maximizing CZ or the Point Cloud Window (Single Monitor Systems) Depending on screen size, there are times when minimizing one window and maximizing the other window is preferred. The Point Cloud window is designed to always remain over the CZ window to make viewing of the point cloud always available. Maximize the Point Cloud Window 1) Click the Windows button on the Point Cloud s window to maximize it, Maximize the CZ Window 1) Minimize the Point Cloud window or resize the Point Cloud window so that it does not obstruct viewing of the CZ window 2) Maximize the CZ window 3) In the standard toolbar, click to view everything currently drawn Return to Viewing CZ and the Point Cloud Windows If the Point Cloud window was minimized: 1) In the Windows task bar, double-click Cloud windows to show the CZ and Point Adjusting the Point Cloud Display Depending on a scanned object s size and scanned resolution, the point cloud density and point size must be adjusted in order to clearly understand where objects are or are not. The density and point size of a point cloud can be adjusted at any time in the Point Cloud window using the slider bars at the bottom of the window: Adjust the sliders, review the results, and repeat until a desirable view is obtained.

52 Appendix C: Editing Editing Objects Various editing tools are available within CZ. It is beyond the intent of this Workflow to cover all editing functions within CZ, however, a few are addressed below. Selecting Objects Objects can be selected using a combination of any of the following: 1) With no command active, draw a rectangle over the object(s) from left to right. Objects that reside completely within the box drawn are selected. 2) With no command active, draw a rectangle over the object(s) from right to left. Objects that touch the box or reside completely within the box drawn are selected. 3) Use the [Ctrl] key on the keyboard to add or remove objects selected with the cursor Properties To edit an object s properties: 1) In the CZ window, select the object(s) to alter (refer to Selecting Objects, p52) 2) Select the property to edit located under Properties 3) Change the property 4) To deselect the object(s), click within a blank portion of the graphics area OR press [Esc] on the keyboard Layers Layers allow objects associated with that layer to be displayed or hidden quickly. Setting the Current Layer All objects created or inserted are placed on the current layer. To change the current layer: 1) In the CZ window and within the Tool Zone, click Properties 2) Select Show More Layers 3) Select the layer to use located under Editing an Object s Layer Refer to Editing Objects: Properties (p52) Page 52 of 54

53 Hiding/Displaying a Layer To show/hide a layer: 1) In the CZ window and within the standard tool bar, click the Layer Manager Figure 61: Layer Manager button 2) In the Layers menu that appears, select the layer to show/hide 3) Toggle the / button Deleting Objects To delete object s created: 1) In the CZ window, select the object(s) to delete (refer to Selecting Objects, p52) 2) Press the [Delete] key on the keyboard Trim/Extend To trim drawn objects within CZ: 1) In the CZ window, click 2) Select the portion of the object to keep 3) Select the object that defines where the object is trimmed To extend drawn objects within CZ: 1) In the CZ window, click 2) Select the object to extend 3) Select the object that defines where the object is to end Removing Segments While Drawing Sometimes will drawing within CZ, a point is chosen incorrectly for a segment. To remove/undo the last point selected, without exiting the command, press [Esc] on the keyboard. If all points have been removed, pressing [Esc] again will exit the current command and the cursor will return to its normal selection icon (i.e. ). Page 53 of 54
