Abstract

The invention discloses a device for accurately positioning tray holes on the basis of machine vision. The device comprises a framework, an image acquisition device, a conveying device, a positioningdevice and a control system. The conveying device is mounted on the framework, and the image acquisition device is used for acquiring images of trays; the positioning device comprises a fixed barrier,an adaptive barrier, pressure plates and photoelectric sensors for detecting the locations of the trays; the trays, the conveying device and the positioning device have different colors; the controlsystem is mounted on the framework, signals transmitted by the photoelectric sensors can be received by the control system, the image acquisition device can work under the control of the control system, and the acquired images can be processed by an image processing module of the control system, so that the tray holes can be positioned. The device has the advantage that the problems of poor tray hole positioning adaptability, low operation efficiency and positioning precision and the like of industrial seedling growing at present can be solved by the aid of the device.

Description

technical field [0001] The invention belongs to the field of intelligent agricultural equipment, and relates to a machine vision-based precise positioning device and method for tray holes. Background technique [0002] In recent years, with the development of transplanting technology, large-scale industrial seedling cultivation has become a trend. In industrial seedling cultivation, the precise positioning of the tray holes directly affects the efficiency of automatic seeding, selective transplanting and subsequent thinning operations. The existing tray hole positioning is mostly realized by manual judgment combined with purely mechanical structures, which has poor adaptability and poor operation A series of problems such as low efficiency and low positioning accuracy. In order to achieve high-precision, adaptable positioning of hole trays and improve the efficiency of industrial seedling cultivation, a new device and method for positioning hole trays is urgently needed, wh...
