The present application relates to a marker point positioning method, device, computer equipment and storage medium. The method includes: acquiring a plurality of perspective images; selecting a first perspective image and a second perspective image satisfying a first preset condition from each of the perspective images; the first preset condition is used to limit the first The baseline range and the number of marker points of the perspective image and the second perspective image; according to the first marker point with the same code value in the first perspective image and the second perspective image, an initial three-dimensional coordinate set is obtained; according to the initial Set three-dimensional coordinates to determine the three-dimensional coordinates of the marker points of each of the viewing angle images. Through the positioning method of the above-mentioned marker points, it is not necessary to set the initial three-dimensional coordinates of the specific marker points (coded points at the cross-connected lines) in advance to realize the marker points. Positioning, even for code points that are not in the shape of a cross ruler ring, the positioning of marker points can also be achieved, and the applicability is strong.
Description
technical field [0001] The present application relates to the field of photogrammetry, in particular to a positioning method, device, computer equipment and storage medium of a marker point. Background technique [0002] With the rapid development of computers and optical devices, the technology of using optical devices to realize three-dimensional reconstruction of objects has also developed rapidly. Specifically, a digital camera is used as an image sensor to set code points on the surface of the object to be measured. By identifying and detecting the code points, the spatial position of the code points is determined, and then the three-dimensional information of some specific points on the surface of the object to be measured can be realized. detection. [0003] The commonly used positioning method of marker points is usually based on the preset initial three-dimensional coordinates of a specific code point, and then realizes the three-dimensional reconstruction of the c...
