Description

Technical Field

[0001] The utility model relates to the technical field of visual recognition, in particular to a plate level recognition device. Background Art

[0002] Existing plywood is manually screened. Since the appearance of plywood varies greatly, no two boards are exactly the same. The size and location of holes and cracks are different. Therefore, it is difficult to distinguish the difference between good and bad boards by manual selection, let alone to divide them into several grades. In most cases, the distinction is chaotic. It is difficult to distinguish good boards and bad boards together. Therefore, in the field of plywood grade classification, the work is extremely difficult. Moreover, all boards need to be checked once and then taken away to check the next one. Tens of thousands of boards need to be checked every day, which is very labor-intensive, slow and inefficient. Therefore, a board grade recognition device is urgently needed to solve the problem. Utility Model Content
