The invention discloses a terrain vision autonomous detection and identification method for a small celestial body surface sampling point in the technical field of small celestial body surface detection, and the method comprises the steps: configuring a binocular stereo vision camera through a mechanical arm system, so as to achieve the visual imaging of a sampling region, and the identification and measurement of the terrain of the sampling point; firstly, noise in an image is filtered out through a preprocessing algorithm; distortion correction is carried out on the image, and imaging errors caused by a camera optical system are reduced; after binocular epipolar correction is carried out on the images, the left eye image and the right eye image are matched, and a dense disparity map is obtained; calculating the three-dimensional coordinates of the two-dimensional disparity map in a left eye camera coordinate system point by point so as to obtain a three-dimensional point cloud map; sensing ...
