Fruit grader based on image processing

Abstract

A fruit grader based on image processing belongs to the technical field of agricultural machinery and comprises a loading mechanism, a batch-type multi-channel material transport mechanism, a continuous single-channel material transport mechanism, a sorting box and a fruit information collecting mechanism. The front end of the batch-type multi-channel material transport mechanism is provided with the loading mechanism, the upper part of the batch-type multi-channel material transport mechanism is provided with the fruit information collecting mechanism, and the tail part of the batch-type multi-channel material transport mechanism is in vertical connection with the continuous single-channel material transport mechanism which is connected with the sorting box. Due to the effective machinery design, the fruit grader based on image process disclosed by the invention effectively avoids the ghost phenomenon when images are collected without lowering the grading efficiency and effectively improves the grading precision and the grading efficiency by combining with a schedule control method.

Description

technical field [0001] The invention relates to a sorting device in the technical field of agricultural machinery, in particular to a fruit sorting device based on image processing. Background technique [0002] At present, machine vision is widely used in the detection of fruit appearance quality. The camera collects the surface image of the fruit, and then transmits it to the computer. Through image processing, the external quality characteristics such as the size, color, and defect of the fruit image are obtained, and then the fruit is graded according to the national fruit grading standard. At present, the more common ones are single-channel sorter device and multi-channel fruit sorter device. The single-channel sorting machine is the most common sorting equipment. The fruit is automatically loaded by the feeding mechanism. During the feeding process, a mechanical device is used to arrange the fruit in a single row. A camera is installed above the assembly line. When th...

Problems solved by technology

[0005] The present invention aims at the above-mentioned deficiencies existing in the prior art, and provides a fruit sorting device based on image processing, which can avoid image ghosting caused by the existence of camera exposure time and the movement of transported fruits in the prior art, and improve the quality of the collected images. Fruit image quality reduces the difficulty of image processing; RGB images and near-infrared images of multiple fruits are collected at one time, and the fruit mask image obtained by using the large brightness difference between the near-infrared image fruit and the background is used to remove the RGB image at one time Background: The defect extraction of multiple fruit surface information images is completed at one time, which improves the efficiency of fruit quality feature extraction; by increasing the number of cameras and the tumbling action of intermittent multi-channel transmission rollers, most of the surface information features of fruits can be collected , which improves the sorting accuracy and realizes the high-speed and efficient scheduling control of batches of fruits by the sorting mechanism
