The invention relates to the technical field of computer vision, and discloses a litchi fruit quality detection method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining the variety of a to-be-detected litchi, and determining a specified excitation wavelength corresponding to the variety of the to-be-detected litchi; setting the excitation wavelength of fluorescence spectrum analysis equipment as the specified excitation wavelength; fluorescence spectrum data and multispectral image data of a plurality of different surface areas of the to-be-detected litchis are obtained respectively, the fluorescence spectrum data and the multispectral image data corresponding to the same surface areas are associated, and the sum of the different surface areas covers the whole surface of the to-be-detected litchis; inputting each group of associated fluorescence spectrum data and multispectral image data of the to-be-detected litchis into a pre-trained fruit quality prediction model, and outputting a quality degradation prediction result of the to-be-detected litchis; and rapid, accurate and lossless prediction of the quality condition of the litchi fruits is realized.

This invention discloses a pneumatic clamping peach tree high-altitude fruit picking device, including an extension rod. The upper end of the extension rod is equipped with a clamping mechanism for gripping and picking peaches. The clamping mechanism includes a fixed plate, supports, a fixing ring, a cylinder, fixing blocks, a connecting rod, grippers, a movable frame, a moving rod, and a transmission rod. A fixed plate is fixedly mounted on the upper end of the extension rod. Several supports are evenly fixed around the upper surface of the fixed plate. A fixing ring is fixedly mounted on the upper end of each support. A cylinder is fixedly mounted in the center of the upper part of the fixed plate. Several fixing blocks are evenly fixed around the upper perimeter of the fixing ring. This invention can be used for peach fruit picking; it also allows for continuous picking. After each picking, the peach can be released directly, and it will first enter a collection net bag, then slide down to ground height via a connecting hose. This greatly improves picking efficiency and facilitates widespread use.
