Detection system and method, computer device, and computer readable storage medium

A detection system, comprising a laser, a camera unit, and a computer device, wherein

• the camera unit is mounted in an upper region of a measured object, the laser is mounted directly above the measured object, and an emission port of the laser is directly facing the measured object;
• the laser is configured to project a laser plane, and the laser plane intersects a surface of the measured object to form laser lines, wherein the laser lines divide the surface into multiple distinct regions of interest;
• the camera unit is configured to capture images of the measured object from different shooting angles, wherein each image comprises a portion or an entirety of each region of interest;
• and
• the computer device is configured to segment and stitch all the images based on regions of interest comprised in each image, thereby obtaining a target image of the surface,
• wherein the computer device is configured for
• segmenting a to-be-processed image to obtain multiple segmented images based on a position of the laser lines in the to-be-processed image, wherein the to-be-processed image is any one of all the images;
• selecting a segmented image with a maximum proportion of the regions of interest from the multiple segmented images as an image to be stitched corresponding to the to-be-processed image;
• traversing all the images to obtain the image to be stitched corresponding to each image;
• and
• according to a predetermined reference coordinate system, unfolding and stitching each image to be stitched to obtain the target image.
