要求精度 meaning in Chinese

adequate accuracy
precision prescribed
required accuracy

In the stereo vision system of a lunar rover , the parameters of the cameras are fixed in the working and the requirement of precision is relatively low . therefore conventional calibration technique is selected after analyzing the merits and defects of various kinds of calibration methods
在月球车立体视觉中,由于摄像机的参数不经常变化,并且要求精度较高,因此本文通过分析各种摄像机标定方法的优缺点,将传统的摄像机标定方法作为首选。
Since the camera lens used in computer vision sustain a lot of nonlinear distortion , recent research efforts has been concentrated on the distortion correcting technique . the optimization algorithms in conventional calibration field have shortcomings that the computing quantity is colossal . in order to improve it , tsai two steps ’ algorithm was developed in conventional camera calibration in this dissertation , and a calibration algorithm considering radial distortion
由于摄像机镜头存在着畸变,对于要求精度定位的应用,需要进行畸变校正,而传统的标定算法中存在着计算量大的不足,本文采用tsai氏两步标定法是考虑一阶径向畸变的摄像机标定算法,与其它优化算法相比具有简单实用、计算量小的特点,并通过实验验证了该算法的可靠性和有效性。
