Seedling replanting system based on machine vision

Abstract

The invention discloses a seedling transplanting system based on machine vision and consists of components of seedling transportation, machine vision identification, control and transplanting. A conveyor belt of the seedling transportation component can convey seedling plates to the transplanting positions and automatically convey after the completion of the transplanting; color images obtained from the machine vision system are used for detecting a plurality of appearance growth indicators such as the size, the number of leaves of the seedlings so as to comprehensively judge whether the seedlings are suitable for transplanting and meanwhile determine the location information of the seedlings to be transferred to the control system by a computer through a serial communication interface RS-232; then the PLC of the control system sends commands to an end effector to realize automatic transplantation of the seedlings through the control system; the end effector adopts shovel-shaped fingers driven by a linear cylinder and meets the seedling transplanting demand for seedling plates with different sizes through regulating the angle of fingers. The invention utilizes the vision system to obtain the growth and location information of the seedlings and realizes the transplantation through the control of the computer and the PLC.

Description

technical field [0001] The invention relates to an automatic transplanting system in facility agriculture, in particular to a machine vision-based seedling transplanting system. Background technique [0002] Facility agriculture greatly reduces the dependence of crop growth on environmental conditions. With the rapid development of facility agriculture in my country, the planting area of ​​facility agriculture in my country continues to expand, and the number of planting varieties is increasing. Therefore, the demand for mechanization and automation in facility agriculture, No matter in terms of quantity or quality, there are new requirements. Due to the unfavorable working environment of high temperature and high humidity in the facility, coupled with the high intensity and repeatability of transplanting operations, the development of automatic transplanting equipment can greatly improve the working conditions of operators, and at the same time improve operating efficiency. ...

AI Technical Summary

Problems solved by technology

Although foreign countries have transplanting equipment that can judge whether a seedling is a hole based on the size of the leaf area, the accuracy of the judgment needs to be improved, and there is no comprehensive factor such as the number of leaves of the seedling, the growth area, and the circumference to judge whether it is suitable for transplanting. plant

Moreover, the grasping fingers are fixed, and there are few suitable transplanting crops, and the applicable hole tray specifications are also fixed, so the applicability is not high

In China, similar automatic transplanting equipment is still blank.
