  • In Getting the depth value

    thanks jakaskerl . one more question. I tried to run the program spatial-tiny-yolo.py from the depthai-python repo, I get the x,y,z value of detected object. In that code, it is stated that those values is relative to the center of depth map. what does it mean? is it as same as the camera frame ?

        Does anyone know how to get the depth data of particular pixel (x,y) ?

        • In Do I need to recalibrate the OAK-D and sync the IMU for VIO ?

          I am working with OAK-D POE. I tried to run the example code of sdk-examples from SpectacularAi (mapping_ros.py) and visualized it on RVIZ. At first, the odometry data (vio result) looked fine, but it went up or down over the time on RVIZ even though i didn't moved the camera up or down. Does anyone know what is the cause of that ? Do I need to recalibrate the OAK-D and sync the IMU for VIO ?

          • In High latency and low bandwidt on OAK-D POE

            I used this OAK-D by connecting it to the POE injector and router. I accessed the OAK-D POE data wirelessly. Does the latency and bandwidth of OAK-D POE depend on all those things I mentioned before (LAN cable, POE injector, and wireless connection ) ? If it does, Is there any solutions to overcome this issue ?

            • In Error when trying to run the new model instead of tiny yolov4 model

              Hi guys. Iam using OAK-D POE. I tried to to run the example code provided in SpectacularAi (depthai_combination.py) that uses depthai library. I tried to use my custom model (file.blob), by running the code. After running the code with new model, I got issue

              • Input image (416x416) does not match NN (640x640)
              • Mask is not defined for output layer with width '6'. Define at pipeline build time using: 'setAnchorMasks' for 'side6'.
              • [critical] IMU driver failed with error code 1. Your board likely doesn't have IMU!

              Does anyone know how to solve this ? and any reference relate to setNumClasses, setCoordinateSize, setAnchors, setAnchorMasks, dan setIouThreshold provided in https://docs.luxonis.com/projects/api/en/latest/components/nodes/yolo_detection_network/

              • In OAK-D POE is experiencing lag

                I am running the OAK-D POE in the ROS2 environment. My OAK-D camera is directly connected to a Raspberry Pi. However, when I tried to access the camera from my laptop, which is on the same network as the Raspberry Pi, I encountered an issue. Upon launching the 'ros2 launch depthai_examples stereo_inertial_node.launch.py' command, the '/color/camera' topic appears in RVIZ. The problem is that it is experiencing lag. I have already made some changes to the parameters in the camera.yaml file, such as setting 'rgb.i_low_bandwidth' to true and 'i_fps' to 60.0. Despite these adjustments, the lag persists. Additionally, when I ran 'ros2 topic hz /color/image', I observed a maximum rate of 1.848 Hz, which does not match the fps I set. Does anyone know how to resolve this issue
