I always encounter this type of error when I try to use ORB-SLAM3. I am using a Pi camera and ICM 20948 and Raspberry pi 4 operating system. My orb slam monocular mode is functioning, but inertial monocular mode is not operational. I already did kalibr to extract the parameters of camera imu extrinsics.
