Embodiment Construction

[0017] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] Whole melon and fruit quality recognition system structure of the present invention is as follows figure 1 As shown, it consists of three parts: an image acquisition system 1 , an optical imaging system 2 and an optical fiber sensor 3 .

[0019] The optical imaging system 2 includes a light box housing 6 , a 220V lighting point light source 8 , a scattering ground glass 7 , a color CCD camera 9 , and a camera bracket 16 . Two cameras 9 are symmetrically installed on the camera bracket 16 fixed on the top of the light box shell 6, the angle between the cameras 9 is 120 degrees, and the normal distance to the surface of the fruit 15 to be checked is 15-20 cm. While ensuring the acquisition of complete fruit surface image information, image distortion caused by too close a distance between the fruit 15 and the camera 9 can be effectively ...

Abstract

A high-speed melon-fruit quality valuating system based on machine's visual sensation is composed of image pick-up system, optical imaging system and optical fibre sensor. The said optical imaging system consists of a lighting box with brosted glass on its inner surfaces, two color CCD cameras, and dot light source uniformly arranged in said box. The said image pick-up system has two image pick-up cards connected to said two color CCD cameras and triggered externally. The said optical fibre sensor can generate periodical level signals to control the pick-up of image. The image is post-treatedby the image processing unit of industrial control computer.

Description

Technical field: [0001] The invention relates to a high-speed melon and fruit quality identification system based on machine vision, which uses external signal trigger control image acquisition, double CCD three-dimensional stereo vision and color image processing technology to realize high-speed, high-resolution and non-damaging discrimination of the external quality of melons and fruits , belongs to the field of agricultural machinery technology. Background technique: [0002] my country is a big fruit producing country, the output ranks first in the world, but the export volume only accounts for about 1% of the total output, and the trade volume only accounts for about 2% of the world's melons and fruits. The reason for this situation is that the production efficiency, comprehensive quality and commercialization level of fruit products in my country are low, and compared with developed countries, there are obvious gaps in many aspects. The proportion of processed product...
