Abstract

The invention belongs to the technical field of screen detection and provides a screen detection system and method. The system includes an electric shift platform: used to set the marked feature points at a certain distance from the detection target; image acquisition device: used to take pictures of the detected target at a certain interval, and make the adjacent images captured have marked feature points; Processing device: used to perform image splicing and fusion processing by capturing marked feature points in the image, and obtain the screen detection result according to the processed image. The screen detection system and method of the embodiment of the present invention sets a specific mark on the detection target as the key point of panoramic stitching before acquiring the image, which reduces the number of feature points and improves the efficiency of the image registration algorithm. The present invention can stitch multiple images at the same time , and is suitable for splicing with multiple cameras; by splicing and fused image results to determine whether the screen is a standard screen, the screen inspection technology is simpler and more efficient, and the cost of industrial inspection is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of screen detection, and in particular relates to a screen detection system and method. Background technique [0002] The rise of Apple mobile phones has also improved the technical standards of mobile terminals, especially the flatness of the screen. When producing screens in batches, it is necessary to detect all screens to determine whether they are standard screens. Screen detection systems have a strong demand in the current industrial field, but so far there is no effective real-time detection of screens. system. [0003] In the prior art, Chinese patent application No. 201110157876.3 discloses a method and device for positioning a screen, specifically, a method and device for positioning a screen by using the principles of computer vision and pattern recognition. The method includes: (1) Acquisition of reference image; (2) Acquisition of screen image; (3) Image recognition; (4) Position calculation;...
