摘要
提出了一种基于MEMS自校准双目测距方法。利用IMU姿态传感器与三轴伺服电机作为摄像头光轴自校准平台,采用双目相机成像模型进行测距。结果表明,该方法利用IMU姿态传感器可以有效地校准摄像头光轴,使其完全平行,同时双目相机成像模型测距精确度和速度较高,满足视觉测距的精确性、快速性需求。
In order to solve the problem of camera alignment error in binocular ranging method,a self-calibration binocular ranging system based on MEMS is proposed.The method uses IMU attitude sensor and three-axis servo motor as the camera optical axis self-calibration platform,and uses binocular camera imaging model for ranging.The results show that the method can effectively calibrate the camera optical axis by using IMU attitude sensor,and make it completely parallel.At the same time,the binocular camera imaging model has high ranging accuracy and speed,which meets the requirements of visual ranging accuracy and rapidity.
