OPT8241-CDK-EVM: Voxel Viewer Software question

Mickey Zhang

Part Number: OPT8241-CDK-EVM

Hi team,

The customer has three questions for the Voxel Viewer Software as below:

Q1. Can the .vxl file which is saved in the Voxel Viewer Software be converted to the .pcd file or the .ply file?

If it can be achieved, would you explain how to achieve this?

Q2. How to get the single frame cloud through using  the Voxel Viewer Software?

Q3. How to use the .dat file and the .bin file which are exported by the Voxel Viewer Software?

The customer does not know the application of the .dat file and the .bin.

Best Wishes,

    Hi Mickey, 

    1) There is an option to export the point cloud as a pcd in VoxelViewer. 

    2) For getting a single frame point cloud, pause the stream and right click on the point cloud. There is an option to export to point cloud: 

    3) The .dat/.bin files contain the phase/amplitude/ambient/flags/depth/other file types. These are binary files containing data of all the frames. THe data type depends on the type of data. For example, for amplitude/phase, the data type is uint16, while for ambient/flags, the data type is uint8. In each of the case, the data is stored in a column-major order, for each of the frames present in the vxl. You can use this to get the correct depth and amplitude resolution.

    Hi Suramya,

    Thanks for your reply. I also have some questions to verify.

    Q1. If the customer need to convert the .vxl file to .pcd file, he can do this as your explanation 2),

    and this can also get the single frame cloud, correct?

    Q2. As your explanation 3), how to use the .dat file and the .bin file when he get the the .dat file and the .bin file?

    I note a post : e2e.ti.com/.../503049

    In this post, can I recommend the ExtractionOfCSVFromVoxelViewer.zip file to the customer to use the .bin file?

    Yes, the customer can get a single frame point cloud using the explanation given earlier.

    The link you shared shows how to extract the files. The customer can write a small code for using the bin file or Extract it using ExtractionOfCSVFromVoxelViewer.zip.

    Alternatively, they can use the C++ release of the VoxelSDK source code and retrieve all the data:
