    I am using voxl2 with flight core in a custom frame with a TOF sensor. I understand that I have to change the coordinates in extrinsics.conf file. Please give me a detailed answer what all changes I have to make in extrinsics.conf file for imu positions (which imu is for qvio and flight-core etc.). Is there anything else that I have to change other than extrinsics and mavlink configuration file for this set up?

      Extrinsics and QVIO server configuration will determine camera orientation and which IMU to use respectively.

      https://docs.modalai.com/configure-extrinsics/

      server/config_file.h · master · voxl / VOXL SDK / Services / voxl-qvio-server · GitLab

      GitLab (gitlab.com)

      You will need to measure from the IMU (Parent) to child (camera) for translation in meters and also the roll, pitch, and yaw in degrees. I recommend watching the video on the configure extrinsics page.

        @Steve-Turner Which imu should be used for imu_px4 in extrinsics file ? Will it be the same as voxl2's imu_px4 or it will be flight-core's imu?

          Will be the VOXL2 IMU's.

          https://docs.modalai.com/configure-extrinsics/#voxl2 recommends using imu_apps for configuration.
