Research Progress on Crack Identification Methods of Agricultural and Livestock Products

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.
