农副产品裂纹识别方法研究进展

Research Progress on Crack Identification Methods of Agricultural and Livestock Products

摘要:

部分农产品和禽蛋产品生产加工过程中不可避免会产生裂纹，坚果加工过程中需要产生裂纹，而禽蛋和谷物类储藏加工过程中尽可能避免产生裂纹，因此识别农产品和禽蛋产品裂纹并将裂纹产品分选出来，对农产品和禽蛋产品生产加工具有重要意义。综述了国内外利用声学振动和机器视觉识别这两种方法在部分农产品和禽蛋的产品裂纹识别方面的研究现状，以及识别的特点。通过现状分析指出，两种方法结合将进一步提高农产品和禽蛋产品裂纹的识别率。

Abstract:

Crack inevitably happens in some agricultural and livestock products during the producing and processing. In some cases，it is needed in producing and processing nuts，whereas it should be avoided in storing and processing egg and grain as far as possible. Therefore，it is of great significance to distinguish crack and sort out the products with crack in the producing and processing. The research status of crack identification on the part of agricultural and livestock products as well as identifying characteristics by using machine vision and acoustic vibration are clarified at home and abroad in this review. The identification rates of the agricultural and livestock products crack would be improved by combining two methods together through the analysis of the research status.
