Device for nondestructive testing of defects of hoxiu pears and use method

Abstract

The invention relates to a device for nondestructive testing of defects of hoxiu pears and a use method, which belong to the technical field of agricultural engineering. The device for the nondestructive testing of internal and external defects of the hoxiu pears is characterized in that the device comprises an illumination system, a transfer system, a detection system and an analytical judgment system; a camera and an image acquisition card acquire a fruit body image, and each sample is knocked by a knocking stick with a force of 15N for two times at both ends of the equator of a fruit body; and an audio signal and an image signal of the sample recorded by a sound level meter are converted and enter an industrial computer for image and acoustic analysis treatment after the fast Fourier transform to obtain a classification result of the sample. The device optimally utilizes computer vision information and vibration spectrum information to perform system identification and detection on the internal and external defects of the hoxiu pears, and has the advantages of quickness, accuracy, stability, broad identification range and the like. The device can be used for aspects of the hoxiu pears such as separation, control of processing process and the like, and is favorable for improving the sales added value of the hoxiu pears.

Description

technical field [0001] The invention relates to a device and usage for non-destructive detection of defects in Fengshui pears. It is a method and device for non-destructive detection of defects in Fengshui pears based on computer vision and vibration spectrum analysis fusion, and belongs to the technical field of agricultural engineering. Background technique [0002] With the improvement of people's living standards, the consumption of fruits has shifted from focusing on quantity to focusing on quality. At the same time, how to change the status quo of low added value of my country's agricultural products export and generate income for farmers and fruit processing enterprises has become a major issue in fruit circulation, storage and testing in recent years. Most concerned issues. [0003] Pear fruit belongs to the Rosaceae, and the subfamily Pear belongs to the deciduous fruit tree. my country is the country with the largest planting area and the highest output of pear tre...
