摘要
设计一种适用于长波红外摄像机的标定装置,并用此标定装置对长波红外摄像机进行标定。通过拍摄多张红外标定板图像,并提取图像上圆孔特征点的像素坐标,利用每个像素点的与空间实际三维坐标点的一一对应关系,结合Open CV摄像机标定函数库,求解出长波红外摄像机的内外部参数,并利用求得的畸变系数,对畸变图像进行矫正。本研究中的标定装置能有效解决长波红外摄像机标定的问题,同时验证了Open CV函数库在摄像机标定程序开发中的具有标定结果精确、运算效率高、跨平台移植性好等优点。
To design a calibration device which is suitable for long wave infrared camera, and calibrate long wave infrared camera using the calibration device. Multiple images of calibration board were shot, and pixel coordinates of circular feature points in images were extracted. With the relationship between pixel point and corresponding 3D point, OpenCV camera calibration function library was combined and utilized to solve the intrinsic and extrinsic parameters of long wave infrared camera. Then the distortion images were corrected by the distortion coefficient acquired. The calibration device can be used for long wave infrared camera calibration effectively. At the same time the research and experiment verified the OpenCV function library has the advantages of precision calibration results and high calculating efficiency, and has a good property for the application to multi-platform in program development of camera calibration.
