Abstract
The present disclosure provides a method and an apparatus for determining an attitude angle of a camera fixed to a rigid object in a vehicle along with an Inertial Measurement Unit (IMU). In some embodiments, the method includes: obtaining IMU attitude angles outputted from the IMU and images captured by the camera; determining a target IMU attitude angle corresponding to each frame of image based on respective capturing time of the frames of images and respective outputting time of the IMU attitude angles; and determining an attitude angle of the camera corresponding to each frame of image based on a predetermined conversion relationship between a camera coordinate system for the camera and an IMU coordinate system for the IMU and the target IMU attitude angle corresponding to each frame of image.
