The invention provides a dynamic image alignment method based on the projection difference of target vectors in an image plane intersecting line. The method comprises the steps of obtaining two frames of image information collected by different collection devices, constructing a target vector for each frame of image information respectively, calculating the length of the parallel projection of each target vector in a corresponding image plane, calculating the inclination angle of each target vector on the image plane according to the length of the parallel projection, and calculating the projection length of each target vector in an image plane intersecting line according to the inclination angle and calculating the projection difference of the projection lengths of the pre-corresponding target vectors of two frames of images, wherein two frame image information corresponding to a minimum projection difference is aligned images. According to the method, through adjustment, the projection difference of the projection lengths of the pre-corresponding target vectors of two frames of images is minimized, the two frames of image corresponding to the minimum value of multiple minimum projection differences are the aligned images, asynchronized images are aligned synchronously, the high precision intersection of the aligned images is facilitated, and the spatial position of a target image is accurately determined.
Description
technical field [0001] The invention relates to the field of image processing, in particular to a dynamic image alignment method based on the projection difference of an object vector on an image plane intersection line. Background technique [0002] At present, in the existing optical intersection measurement, multiple images with time synchronization are intersected, that is, the synchronous images are synchronously aligned to obtain the spatial position of the target image. [0003] Specifically, two acquisition devices are used to capture static images or synchronously moving images at the same time, and then intersect the acquired synchronous images to obtain the spatial position of the target image. [0004] However, at present, for the asynchronous moving dynamic target collected, since it is an asynchronous image, intersecting it will bring a large error, cannot intersect with high precision, and thus cannot accurately determine the spatial position of the target ima...
