Dynamic visual displacement measurement method based on automatic encoder

The invention relates to a dynamic visual displacement measurement method based on an automatic encoder. The method comprises the following steps: S1, constructing feature points attached to the surface of a cylinder; S2, performing dynamic video data acquisition on the cylinder attached with the feature points by using a binocular acquisition system to obtain left and right view data sets; S3, extracting target feature points according to the obtained left and right view data sets, and obtaining image two-dimensional coordinates of the obtained feature corner points; S4, performing calibration processing on the binocular acquisition system to obtain an internal parameter matrix and an external parameter matrix of the binocular camera; S5, reconstructing a three-dimensional world coordinate set of the feature points according to the obtained internal and external parameter matrixes of the binocular camera and the image two-dimensional coordinates of the feature angular points; and S6,performing cylinder fitting by utilizing the three-dimensional world coordinate set of the feature points according to the cylinder structure, and performing calculation to obtain a rotating Euler angle. The displacement and rotation angle information of the target in the dynamic video can be calculated by collecting the feature point information of the target object, and the target object does not need to be directly contacted.
