Problems solved by technology

Computer vision recognition technology is widely used in various screening industries. Computer vision is used to automatically complete the recognition and screening of objects, saving a lot of labor costs and improving screening efficiency. For example, the fruit conveyor line needs to separate good products and defective products. Using computer identification, but the fruit photo identification on the existing vibrating conveyor line is difficult to capture the whole picture of the fruit, which reduces the screening effect

Abstract

The invention relates to the technical field of screening equipment, in particular to screening equipment based on computer visual identification. The screening equipment comprises a bottom plate, a first conveying line, a fourth mounting rack, a barrel, a fifth mounting rack, a third conveying line and a fourth camera; a third mounting rack is arranged on the second mounting rack, and a sensing assembly is arranged on the third mounting rack; a supporting rod is arranged on the first conveying line; a supporting disc is rotationally arranged at the top of the supporting rod; an iron ring is arranged on the supporting disc; two groups of first cameras and one group of second cameras are arranged in the third mounting rack; a first power assembly for placing the barrel on the iron ring is arranged on the fourth mounting rack, a magnetic ring is arranged at the bottom of the barrel, and the top of the barrel is closed; a second power assembly used for taking down the barrel and pushing the barrel to the third conveying line is arranged in the fifth mounting rack; and the fourth camera is located over the third conveying line. According to the screening equipment, the screening body is subjected to comprehensive camera recognition, the situation that the bottom of the screening body cannot be recognized does not exist, and the camera identification accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of screening equipment, in particular to a screening equipment based on computer vision recognition. Background technique [0002] Computer vision refers to the use of cameras, computers and other related equipment to simulate biological vision. Its main task is to process the collected pictures or videos to obtain the three-dimensional information of the corresponding scene, and further perform graphics processing to make computer processing It becomes an image that is more suitable for human eyes to observe or sent to the instrument for detection. Computer vision recognition technology is widely used in various screening industries. Computer vision is used to automatically complete the recognition and screening of objects, saving a lot of labor costs and improving screening efficiency. For example, the fruit conveyor line needs to separate good products and defective products. Computer recognition is used...
