System for detecting sowing quality of rice seedling raising disk and application thereof for detecting

Abstract

The invention relates to a seedling nursery disc planting quality testing system and the application in testing. In the system, a conveying belt passes under a pair of cameras; a planting device is arranged above the conveying belt between the pair of cameras; the output signals of the two cameras are connected with a PC, and the program of the PC includes an image processing software. During the application, the conveying belt drives the seedling disc to run to a position below the inlet end, and the camera obtains the image information of the seedling disc prior to planting; when the seedling disc runs to a position below the outlet end of the camera, the camera obtains the image information after planting; the PC obtains the testing result through comparing the information of two images by an image processing software. The invention has the advantages that the complete testing process is free of contact, damage and pollution; human interference and influence are reduced, and the reliability of testing is improved; besides high testing efficiency, the man power and material resources are reduced, and the production cost is lowered.

Description

technical field [0001] The invention relates to a detection system of a PC machine in sowing seedling trays and its specific application. Background technique [0002] The quality of seedling tray raising is the key factor affecting the quality of mechanical transplanting. The common means to ensure the quality of seedling raising is first to inspect the seedling quality of seedling trays. At present, these inspections are mainly done manually. The plastic template is covered on the seedling tray where the seedlings have been sown (the grid size is the area of ​​seedlings taken by the rice transplanter), and the number of seeds in each grid is counted and recorded, and then the average number of seeded seeds in each hole, the pass rate of uniformity, and Missed broadcast rate and replay rate and other indicators. This method is inefficient, labor-intensive, time-consuming, and has large errors, which seriously restrict the promotion of mechanical rice transplanting technolo...

Problems solved by technology

[0004] The purpose of the present invention is to: aim at the current manual calculation of the average seeding number in each hole, the pass rate of uniformity, the missed seeding rate and the reseeding rate and other indicators, which are inefficient, labor-intensive, time-consuming, and have large errors, which seriously affect the vigorous promotion of mechanical transplanting technology. Provide a kind of seedling tray seeding quality inspection system and its application example in inspection
