基于多视角图像的几何参数测量方法研究

Geometric Parameters measurement Based on Multi-view Image

受到大自然中昆虫复眼独特结构的启发,提出了一种以多目立体视觉为基础的多视角图像测量方法;通过旋转数码相机获取多视角图像,在多视角图像匹配以及摄像机的自标定技术的基础上,利用摄像机的内外参数和多视角图像测量方法完成特征点的空间位置和物体尺寸的快速测量;实验证明测量结果误差在1%以内,说明该方法解决了传统测量方法中测量范围与精度不能同时满足要求的问题,并在速度以及智能化方面具有优越性。

Inspired by the unique structure of compound eye of insects in the nature, a measurement method of multi view image based on muti view stereovision was presented in this paper. Multi view image sequence were obtained hy rotating the camera, according to the internal and external parameters of the camera the space position of the feature points and the size of object were calculated quickly based on multi--view image match and the technology of self--calibration of the camera. Experiments prove that the measuring result error within 1% ; and it indicates that the method solves the problem of the measuring range and accuraey can＇t meet the requirements at the same time, which exists in the traditional measurement methods, and there are superiorities in the speed and intelligence as well.
