The invention discloses a mark point recognition method, which comprises the following steps: acquiring an object motion image acquired by a camera, numbering pixel points in the object motion image from 0 to n-1, n being the number of the pixel points in the object motion image; calling a graphics processor, and creating n-1 thread groups in the graphics processor; in the created ith thread group, whether track intersection exists between a pixel point i and a pixel point j in the object moving image or not is judged through threads executed in parallel, i and j are numbers of the pixel points, i is larger than or equal to 1 and smaller than or equal to n-1, and j is larger than or equal to 0 and smaller than or equal to i; If track intersection exists between the pixel point i and the pixel point j in the object motion image, obtaining the position of an intersection point, and taking the position of the intersection point as the position of a motion capture mark point. The inventionfurther discloses a mark point recognition device and equipment and a storage medium. According to the method, the recognition efficiency of the motion capture mark points is improved, and the calculation time consumption is reduced.
