查询词典 camera

The method comprises the following: a step of calibrating a camera, which is to utilize a Taylor series model to calibrate an omni-directional vision sensor so as to obtain internal parameters of the camera; a step of obtaining epipolar geometric relation, which comprises the steps of calculating an essential matrix between binocular omni-directional cameras and extracting the rotation and translation component of the cameras; a step of correcting an outer polar line, which is to correct the outer polar line of a shot omni-directional stereo image so as to allow a corrected polar quadratic curve to coincide with an image scan line; and a step of three-dimensional reconstruction, which is to carry out feature point matching to the corrected stereo image and calculate the three-dimensional coordinates of points according to matching results.

该方法的步骤包括：相机标定：利用泰勒级数模型对全向视觉传感器进行标定，得到相机内参；对极几何关系求取：包括计算双目全向相机之间的本质矩阵，并从中提取相机的旋转和平移分量；外极线校正：对所拍摄的全向立体图像对进行外极线校正，使校正后的极二次曲线与图像扫描线重合；三维重建：对校正后的立体图像对进行特征点匹配，根据匹配结果计算点的三维坐标。

From the concept, it does the exact opposite of a camera: instead of recording an image of the environment by means of an orthographic or perspective projection, projective texture mapping projects an image onto the environment, by using a matrix very similar to the one a camera uses.

从这个概念上，它与摄象机正好相反，不是通过正交或者透视投影来记录环境的图象，而是把图象投射到环境上，通过使用类似于摄象机使用的矩阵。

Research on the theory of structure light sensor Originating from the principles of projective and perspective transformation, for the first time, the models of coordinate transformation between workpiece and camera with arbitrary angle of laser light and camera are presented.
