projective transform造句
例句与造句
- the projective transform occurs in the 2-d imaging process, therefore in order to recognize airplane object, we have to find projective-invariant shape descriptor of object
由于目标的成像过程属于射影变换，因此为了正确识别目标，必须找到一种具有射影不变性的目标形状的描述方法。 - another important content in this chapter is that we linearly calibrate the nonlinear parameters of camera based on the rectification features of lens and the fact that projective transform converts a line into a line
本章中另外一个重要的内容是，基于透镜畸变的特点并根据射影变换保持直线不变的约束条件，线性地确定非线性内参数。 - moreover, according the information of vehicle corner, this paper adopts kalman filter to track each moving vehicle and uses optic projective transform to partially resume the depth of these corners, which can check the match result
同时，根据车辆的角特征点信息，将卡尔曼滤波器引入车辆跟踪算法中，并借助光学投影方程部分恢复待匹配角特征点的高度信息，以检查匹配算法的准确性。 - in the self-calibration scheme, the thesis emphasizes the accuracy of camera intrinsic and extrinsic parameters . we presents an accurate f method based on corresponding point adjustment . the method adjusts coresponding points according to the fixedness of projective transformed cross ratio, then calculates f matrix accurately through linear and non-linear methods . when computing intrinsic parameter, a matrix, we simplify the step, and stress on the two important parameters of a . the result will be getten through solving kruppa equation based on svd decomposition . in order to compute extrinsic parameters, we use linear method to get initial r and t, then apply non-linear method to accurate them
提出了基于匹配点调整的f求精方法，先根据摄影交比不见性对手工选择的匹配点进行调整，再用线性、非线性结合的方法求精f矩阵；在计算内部参数a中，进行了一定的简化，把重心放在a中重要的两个参数上，用svd分解法计算kruppa方程；在计算外部参数时，首先用线性法求解r、t，然后再用非线性法迭代求精。 - It's difficult to find projective transform in a sentence. 用projective transform造句挺难的
