The Correction Research of Camera Installation Error for Vision-Guide Mobile Robot

To solve camera installation error of vision-guide mobile robot, this paper proposes a vertical and horizontal proportion rectangular deformation method to realize the correction. Based on the law that camera installation error has different effects on the distortion of different areas in imaging plane, the coordinate relation transformation from object stage to camera plane is got by homogenous coordinate transformation, and the correction result be gained by the camera installation error correction matrix. It is demonstrated that the proposed correction algorithm is simplified the parameter model structure and high correction precision.
