Hey, just considering buying the ZED2, but was unsure about two things:
I want to install it on a boat, but I heard, that for IMU calibration, the camera needs to be fixed for a period of time. This assumption is hurt when the boat is slightly moving in dock. Do you think this is a problem?
In rough sea conditions I would like to stabilize the video feed via IMU. Is there a logic for that available somwhere?
This is not true. The IMU is factory calibrated, so you can use it on dynamic systems.
You can experience a slight drift in the warmup phase because the factory calibration is performed at a stable temperature reached after a few seconds after the camera boot up.
What the SDK does is “tune” the calibration at the operating temperature by estimating eventual biases when the accelerometer reveals that the camera is static, but this is an improvement of the parameters, not the full calibration.
We do not provide this feature with the ZED SDK, but you can try to apply camera stabilization algorithms. There are many possible ways all described in scientific papers available online.
