Three-dimensional information acquisition method and device based on line laser and binocular vision

The present invention provides a three-dimensional information acquisition method and device based on line laser and binocular vision. The method includes the following steps that: line laser emittedby a line laser is controlled to be projected onto a measurement object; the left camera and right camera of a binocular camera are utilized to measure the left image and right image of the measurement object respectively, the parameters of the left camera and the parameters of the right camera are identical, in the left image and right image, distances between the measurement object and the edgesof the images are smaller than a first set value; stereoscopic correction is performed on the left image and the right image, so that the corrected left image and the corrected right image are be inline alignment with each other, or the reprojection distortion of the left image and the right image is smaller than a second set value; the corrected left view and the corrected right view are matched with each other, so that
