Description

Technical Field

[0001] The utility model relates to the technical field of image quality recognition devices, in particular to a device for recognizing image quality based on computer vision. Background Art

[0002] With the rapid development of digital image processing and computer vision technology, image quality assessment has become an important task. Traditional image quality assessment methods mainly rely on manual judgment, which is inefficient and easily affected by human factors, resulting in inaccurate judgment. In addition, the workload of manual judgment is large, especially when multiple staff members perform judgment operations at the same time, disagreements will arise due to different levels of judgment, further delaying the evaluation time and causing inconvenience to the staff.

[0003] At present, in order to achieve efficient image quality assessment operations and also to reduce the workload of staff, computers are usually used to identify image quality operations. When using computers for visual image quality recognition operations, a corresponding image acquisition module is generally provided on the computer visual image quality recognition device. When in use, the image is placed under the image acquisition module, and the image recognition operation is performed using the image acquisition module. However, when using this type of computer visual image quality recognition device, it is necessary to manually place the corresponding image under the image acquisition module each time. After the acquisition is completed, other images need to be replaced. Such repeated operations will waste time and cannot realize the automatic delivery of paper images to the bottom of the image acquisition module, which brings inconvenience to users. In view of this, we propose a device for recognizing image quality based on computer vision. Utility Model Content
