Abstract

The invention relates to a portable beef quality classification detector based on an embedded machine vision technique. The portable beef quality classification detector provided by the invention comprises a camera (2), a light source (3), a lamp box (4) and an analyzer (5), wherein the camera (2) and the light source (3) are both integrated in the lamp box (4); a light vent (6) is formed on the box body of the lamp box (4); the camera (2) is fixed on the lamp box (4), and a lens (1) at the front end of the camera (2) is opposite to the light vent (6); the light source (3) is installed on the light vent (6); and the output of the camera (2) is connected with the analyzer (5). The portable beef quality classification detector provided by the invention integrates modules such as an embedded circuit board, a CCD (Charge Coupled Device) industrial camera, an LCD (Liquid Crystal Display) liquid crystal touch screen, Wi-Fi equipment, the light source and the like; all the modules are mutually matched and fixed into an integral; and finally, the integral is packaged by utilizing a designed shell. The integral classification terminal has the advantages of light weight, small volume and strong operating environment adaptation and is easy to manually operate.

Description

technical field [0001] The invention relates to a beef quality intelligent grading detector, especially a portable terminal integrating a light source, a camera, an embedded module and a fixing device. A portable beef quality grading detector based on embedded machine vision technology to determine its quality grade. Background technique [0002] At present, the evaluation indicators of beef quality mainly include beef marbling, beef color, beef physiological maturity and beef fat color, among which the marbling grade is the most important evaluation index. In the traditional beef processing industry, manual measurement or visual inspection is usually used to evaluate the quality of beef. Since the evaluators conduct subjective and qualitative evaluations based on personal experience, they are easily affected by subjective factors such as environment and psychology, and are prone to human eye fatigue and reduced evaluation efficiency. Therefore, such an evaluation process n...
