[0002] With the continuous development of computer vision technology, the rapid product recognition system based on visual recognition has gradually become a research hotspot in the commercial field. Traditional product recognition systems mainly rely on manual operations, which are inefficient and prone to errors, and cannot meet the needs of large-scale and efficient product recognition.

[0003] Existing visual recognition systems often rely on only a single image acquisition device, such as a fixed camera, which has great limitations in practical applications. For example, China's patent authorization announcement number CN218848787U discloses a visual recognition structure for workpieces on a coating production line. It can use machine vision to identify the shape, position and other hanging postures of the workpieces, and combine existing equipment to achieve the purpose of recognition and detection. However, fixed cameras cannot flexibly respond to shooting requirements at different angles, heights and distances. Especially when facing complex environments and changing product forms, the recognition effect is often unsatisfactory.

[0004] Therefore, developing a rapid product recognition system based on visual recognition has important practical application value. Utility Model Content
