Abstract :
The main purpose of this paper is not to present a new camera calibration algorithm or a new pose estimation method, but just to analyse the stability of the camera pose estimation using the Haralick observation which is based on the fact that there is sufficient information on the 2D perspective projection of a rectangle of unknown size in 3D space to determine the three camera look angles. A brief description of the camera look angles computation is presented and a model for the expected stability of the camera look angles computation front noisy image data is described. A stability analysis as a function of the pose of the camera is also described, and the influence of the camera pose is confirmed with simulated data. As a result, camera pose view strategies for accurate camera orientation computation can be extracted from this pose view stability analysis
