  I've run into issues when using the Tau Camera, where can I get help? Start by going over our Troubleshooting Guide. It covers common errors and issues. If you can't find a solution for your problem there, post on the Onion Community Forum and we'll do our best to help out. To make it easier to get help, try running the checkCamera.py Example Python Program and posting the command line output and screenshots of the output if you think it will be helpful.

  @abdullahjhatial And does the same behaviour happen on a different computer? Please also try this suggestion from the thread I previously linked @Indighost said in Onion Tau not working anymore: Use ctrl+c to kill the program and try running it again Unplug the Tau Camera from the computer for 10 seconds, reconnect, and try running the program again Try switching to a high-quality cable! If possible, try using a not-super-long USB-C to USB-C cable from a reputable brand. Then try running the program again.

  @Electro the getUint16LittleEndian method is used for reading 16-bit integers from the Camera. It's used for reading the camera's configuration/settings. See this search for the getUint16LittleEndian method on the tau camera github repo for details of when it's used. For your purposes of finding the closest point in the frame, you should look at the readFrame method. It will return a Frame object with distance/depth. See the related documentation entry for more info. You can see the readFrame method in action, as well as how OpenCV is used to render pictures using the data in the example programs. Enjoy!

  @sriharsha-phd You can't retrieve an RGB image, but you can get a grayscale image. See the distancePlusGrayscale.py example program for more details: Info on the example program The example program source code And the Tau Camera API Reference & Documentation

  Hi @abbas_barwani You should talk to our hardware design partner VSemi if you're interested in the hardware details.

  Hi @Garth-Tuck We don't have any examples measuring dimensions. But all of the Tau Camera software is open source and well documented if you want to build an application that does this. Check out the Tau Camera Useful Links listing for links to the github repos and documentation.

  Hi @JackHulspas Have you tried comparing your open3d point cloud visualizations to the point cloud in the Tau Studio web app? (See step 1 in the Tau Camera Getting Started Guide for more info on the Tau Studio web app) It's possible the open3d library is expecting the data to be ordered differently. I would suggest taking a look at the Tau Camera Python API reference: https://taulidarcamera.readthedocs.io/en/latest/

  @Lazar-Demin Thank you for replying! I shall see if i can use the data_depth method to do what I need. But wouldn't the points_3D be more useful? Since I am trying to find two points on the screen to measure the distance. The 2 points most likely won't be on the same axis, so in order to get the distance between points wouldn't it be better to use the points_3D fuction, as it returns 3D coordinates in meters? Because as as far as I can tell the data_depth method returns how far the point is away from the camera (correct me if I'm wrong). I shall also let you know if I make any progress using data_depth to get the distance, thanks!

  @Rastus Awesome, happy to hear you resolved your issue! I'll add your Jetson setup steps to the FAQ. I don't foresee any issue with using the Jetson to analyze the data - should be a fun project. Do you have any specific libraries in mind? Make sure to keep us in the loop as your project progresses, we love robots - especially those that use the Tau Camera
