OPT8241: OPT8320 getting data from Voxel Viewer and Voxel CLI

Part Number: OPT8241
Other Parts Discussed in Thread: OPT8320

Hello:

I'm working on a project with a Seeed DepthEye 3D visual ToF Depth Camera based on OPT8320, using Voxel Viewer for visualize the data. I try to convert the .vxl file that I get from Voxel Viewer, but I can't convert to .bin data getting the log:

File "PyVoxelViewer\dialogs\ExportRawStreamDialog.py", line 127, in processRawData
File "PyVoxelViewer\models\DepthCameraStreamController.py", line 860, in addFileStreamSource
File "PyVoxelViewer\models\DepthCameraStreamController.py", line 485, in __init__
ValueError: invalid null reference in method 'new_FrameStreamReader', argument 2 of type 'Voxel::CameraSystem &'
Traceback (most recent call last):
File "PyVoxelViewer\MainWindow.py", line 160, in showExportRawStreamDialog
File "PyVoxelViewer\MainWindow.py", line 128, in selectDepthCamera
AttributeError: 'NoneType' object has no attribute 'scan'

Also I tryed with Voxel SDK running VoxelCLI but I only get noise and the sensor start to overheat, I was looking for the course on Time-of-Flight sensors, but there aren't the videos for Voxel Viewer and the Introduccion for Voxel SDK, can you upload the videos for get a better guide of the use of Voxel SDK?

Regards,

Hi Alejandro,

Which version of Voxel Viewer are you using? The latest version (0.9.10) does not have this error. Please tell which version of VoxelCLI you have as well.

There is a Voxel Viewer users guide present here:

Could you elaborate which parts you want explained better?

The documentation for VoxelCLI can be found here:

You can get all the functions of VoxelCLI using the "help" command.

I'm working on a project with a Seeed DepthEye 3D visual ToF Depth Camera based on OPT8320

This camera was not added to VoxelSDK by us. Can you point me to the VoxelSDK code for this camera on Github? Is it on a fork of voxelsdk?

Thanks for answer
I was using the version (0.9.11) of Voxel Viewer downloaded from: github.com/.../DepthEyeSdk
When I installed the version (0.9.10) I get the same with VoxelCLI, just noise and heath on the camera
I want to know how can I configurate this camera for use it, I'm afraid that you not comercialize this device anymore, the OPT8320, I can't find the category on the blog

Sorry if is a basic question, I'm begining with ToF
Regards

Alejandro,

We do not know the register settings of the SEEED camera. Please contact their customer support for the solutions. The viewer they're using is a modified version of the TI Voxel Viewer software. Even the SDK is modified for their own camera. There are too many unknowns for us and it will be best to ask them for support.

OPT8320 will be up on the web again soon.It is not online as of now.
