Initial guess about extrinsic parameters for Camera/IMU #69

Open mokhtarbouain opened 1 year ago

mokhtarbouain commented 1 year ago

Hi all, I aim to use your calibration solution for the camera/IMU. I have a question please, how can I get the initial guess about extrinsic parameters for the camera and the IMU sensors? Does this correspond to the location of the sensors in the vehicle? (like we measure the translation with a meter) Thank you.

An initial value can be obtained according to the corresponding relationship of the sensor's coordinate system. For example, if the direction of the coordinate axis of the sensors is consistent, it can be set as an identity matrix.
