The Colorization workflow includes the capability to colorize with the GoPro Hero MAX. The software comes with image masks, which remove objects such as drone components from appearing accidentally on the point cloud. During colorization, you can pause the workflow and review the frames used to colorize allowing you to delete any frames that cannot removed using the image mask.
Note: Special care must be taken when performing handheld colorization using the 360 camera. It is easy for the user to accidentally appear in the frames and “pollute” the final point cloud.
Warning: It is important to ensure that the correct colorization calibration file matches the GoPro camera serial number when performing the colorization procedure. Not doing so can result in faulty output.
Note: The image extract kit is NOT suitable for colorization. The extendable telescoping mount is not rigid enough for an accurate calibration, which is necessary for colorization.
Reminder: Before you start, ensure that the .mp4 (perspective camera) or .360 file(s) are placed in the scan folder that contains the raw bag files. Open the video files after transferring using a suitable video playback software (e.g., VLC player which works for the .360 format) to ensure the file is not corrupted. This is a great opportunity to see which image mask to use.
Step 1: Process the individual point clouds
For more detailed information on processing point clouds, see Process Workflow.
-
In the Process tab, click Process Scan.
-
In the Configure New Scan Job panel, select the Process workflow.
-
Click Add Dataset.
-
Browse for the folder that contains the raw point cloud dataset to be processed. Select that folder.
-
Click Start to begin processing.
-
View your final output.
-
Repeat the same steps for the other raw scan data to be merged.
Step 2: Merge the processed point clouds
For more detailed information on merging point clouds, see Merge Workflow.
-
In the Process tab, click Process Scan.
-
In the Configure New Scan Job panel, select the Merge workflow.
-
Click Add Datasets.
-
In the dialog box that displays, click Add then browse for the the point clouds you want to align. Make sure all the point clouds have been pre-processed in Aura.
-
In the Alignment Preview File column, select the scan file to merge for each scan folder. Also, select the reference scan file, which provides a fixed frame of reference for aligning the other point clouds.
-
Once you have added all the point clouds to merge, click Save.
-
Manually align your point clouds when prompted. Click Load Scans to start your review. All scans will load at the same time.
-
Click Start to begin processing.
-
View your final output.
Step 3: Colorize the point cloud
For more detailed information on colorizing point clouds, see Colorization Workflow.
-
In the Process tab, click Process Scan.
-
In the Configure New Scan Job panel, select the Colorize workflow.
-
Click Add Dataset.
-
In the dialog box that displays, browse for the folder that contains the point cloud to be colorized. Ensure the scan has been processed and the .mp4 file or .360 file is in the same directory. If the video file is detected, it will appear in the Video file(s) column (multiple video files will appear if detected depending on the scan duration).
-
Once you have loaded the merged point cloud and the corresponding video file, click Save.
-
Click Start to begin processing.
-
When prompted, click Review Frames.
- In the file explorer window, manually delete any unwanted frames from your video.
- Once the unwanted frames are removed, return to Emesent Aura and click Resume.
- View your final output and check the results.
- Repeat the same process for the other merged point clouds.
