基于双目视觉的数码相机定位方法研究

Binocular vision-based positioning method of a digital camera

围绕数码相机定位问题,在合理假设的基础上,首先建立像素、图像、光心、世界4坐标系并推导出坐标转换公式,进而确定相机成像的线性几何模型。其次利用MATLAB读图、确定椭圆形区域和边界点除噪等预处理,最终完成靶标上圆心的确定和相机内部参数的确定,并以共线性的误差来衡量模型求解的精度。

This article on the position of a digital cam- era, based on the reasonable assumption, at first, estab- lish the pixel, image, light heart and the world four - coordinate system and derive coordinate transformation formula, and then determine the linear geometry of the imaging camera model. Then use MATLAB read the images to determine region and border points of the o- val, such as pre - noise, the ultimate target for the com- pletion of the center and to determine the parameters of the internal camera, and use the total error of linear models to measure the accuracy of solving.
