Handheld grape image collection and measurement device

Abstract

A handheld grape image collection and measurement device is disclosed in the invention and includes a grabbing handle, an open-type collection box, a measurement apparatus and a measurement apparatus fixing mechanism. The open-type collection box comprises a collection box body, a bottom plate and a threaded sleeve, wherein the threaded sleeve is fixed on the bottom surface of the bottom plate and the bottom plate is connected to the grabbing handle through the threaded sleeve. On one side of the open-type box body, a clamping groove for fixing a changeable background board is arranged. A measurement scale sliding trough is formed in the bottom board. The measurement apparatus fixing mechanism includes a camera fixing frame and a transversal rod. A U-shaped through trough is formed in the transversal rod. A measurement scale positioning sleeve sleeves the transversal rod and can slide along the U-shaped through trough. The measurement apparatus includes a camera, a changeable background board and a measurement scale. The device is simple and compact in structure and is low in production cost. In the device, the background board can be conveniently changed and the position of a measurement mark can be regulated, so that on-site collection of image of grapes can be carried out conveniently, thereby ensuring accuracy of collected test data.

Description

technical field [0001] The invention relates to the field of agricultural robots, and more specifically, relates to a hand-held grape image acquisition and measurement device. Background technique [0002] In agricultural picking robots, the application of machine vision is a key, and the image acquisition and extraction of picking objects is a core basis of the vision application part of picking robots. All the information that needs to be processed is based on the collected soil boxes. , that is, the image acquisition is the information source of the machine vision system, and the image is collected and stored in an orderly manner through the acquisition device. The performance of the acquisition system directly determines the fundamental information source of the machine vision system. [0003] The existing acquisition system is usually composed of camera equipment, control equipment, storage equipment and transmission equipment. In a normal experiment, if you want to co...
