AI Technical Summary
Technical Problem
Because the images captured by multiple cameras are inconsistent, it is difficult to align the images captured by each camera at the same time, making it difficult to accurately locate the defect area of the part under test during defect detection.
Method used
By acquiring multiple frames of local images captured by multiple cameras, the frame number of each camera is determined and converted into sequenced image data to generate a target image. The target images from multiple cameras are then aligned based on the sequenced image data.
Benefits of technology
It achieves consistency in detection results for the same area of the test piece, accurately locates the defect position of the test piece, and improves detection accuracy and efficiency.

Abstract
The application discloses an image alignment method, an image alignment device, a detection equipment and a nonvolatile computer readable storage medium. The method comprises the following steps: acquiring a plurality of local images captured by a plurality of cameras; determining the frame serial numbers of the continuous local images collected by each camera, and converting the frame serial numbers corresponding to each local image into serial number image data; generating a target image according to each local image and the serial number image data corresponding to the local image; and aligning the target images of the plurality of cameras based on the serial number image data of the target image. According to the application, the frame serial numbers corresponding to each local image are converted into serial number image data, the target image is generated according to the serial number image data and the local image, and the target images of the plurality of cameras are aligned based on the serial number image data of the target image, so that when defect detection is performed according to the aligned target image, the detection result is the area of the same test piece, and the place where defects exist in the test piece can be accurately located.
