Mosaic Calibration of Vehicle-mounted Surround View Images Based on Matching
For the vehicle-mounted surround view system,it is the key and effective equipment to assist safe driving and eliminate the blind area around the vehicle body.The image mosaic calibration board is designed to improve the accuracy of image mosaic calibration and realize automatic calibration,and a calibration method of shape matching is also put forward in this thesis.The calibration plate adopts circular pattern and is arranged according to rectangular and diagonal five points,which is suitable for"F-B-L-R"and"F-B-L-R-Z-Y"and multi-section traction trailer occasions.Then,it realizes the image splicing calibration by combining the least square method,image pyramid and template pre-training based on the shape matching algorithm.According to the simulation experiment,it indicates that the calibration board has good robustness,the algorithm has good calibration accuracy,and is able to achieve the automatic calibration,which lays the foundation for the deep research on vehicle-mounted surround view system.
