A transplanter test bench based on machine vision

Abstract

The invention relates to a machine vision-based transplanter test bed, and aims to provide a transplanter detection device which is high in detection precision, simple in structure, convenient to use, and high in efficiency. The machine vision-based transplanter test bed includes a test bed rack, an electromagnetic speed regulation motor, a power distribution box, a seedling taking mechanism, a seedling feeding device, a planting mechanism, a computer vision device, a displacement sensor and a speed sensor. The computer vision device adopts an industrial camera to be connected with a microprocessor, the displacement sensor is used for detecting accuracy of transverse reciprocating motion of a disk of the seedling feeding mechanism, the speed sensor is mainly used for detecting the rotating speed of a small belt wheel of the power distribution box, the industrial camera detects a seedling taking process of the seedling taking mechanism, a seedling casting process, a seedling feeding process of the seedling feeding mechanism and a planting process of the planting mechanism, data are sent to the microprocessor to be processed, and a success rate of seedling taking, a success rate of seedling casting, a success rate of planting and an optimal working speed are calculated.

Description

technical field [0001] The invention relates to a machine vision-based transplanting machine test bench, in particular to a test equipment for testing the mechanical performance of a transplanting machine, and belongs to the field of agricultural machinery. Background technique [0002] In recent years, more and more crops in our country are planted by seedling transplanting. Seedling transplanting can make full use of the growing season. Seedling raising is carried out in protection, so it is not restricted by the late frost period and can be sown earlier. Centralized seedling cultivation is conducive to the cultivation of strong seedlings. The seedlings in the seedbed are concentrated, occupy a small area, and are easy to manage. It is conducive to artificially controlling the microclimate, adjusting temperature and humidity, strengthening fertilizer and water management, and pest control. Many crops are transplanted using transplanters. [0003] At present, there is no m...

AI Technical Summary

Problems solved by technology

[0003] At present, there is no mature testing platform for transplanting machines. The transplanting machines produced by some manufacturers or the transplanting machines developed by universities rely on manual recording of transplanting test data, and then the data is summarized and entered into the computer. Calculation and analysis, the work is time-consuming, labor-intensive, low-efficiency, large error, labor-intensive, and greatly affected by external factors such as weather, which is not conducive to finding the optimal working parameters and debugging and improvement of various parts of the transplanting machine through experiments.
