[Abstract]:Potato is the fourth largest grain crop in China, with a wide distribution area, but most of the areas are still in the stage of manual separation. Based on this situation, the project team designed a potato grader based on machine vision. After analyzing and processing the image information of potato, the rapid nondestructive sorting of potato size and external defects is realized. In order to meet the requirements of potato image acquisition in the sorting process of potato grader, a potato hierarchical detection image acquisition system based on multi-CCD camera is designed in this paper. The main contents are as follows: (1) in order to extract the surface information of potato completely, four CCD cameras are used to collect the image of potato in the process of flat throwing. The composition of the image acquisition system is analyzed in detail, including PC, four-channel gigabit network card, four CCD cameras, synchronous signal controllers, etc. (2) Multi-CCD cameras need to ensure the synchronization of the camera when collecting moving potato images. Otherwise, the accuracy and efficiency of post-sorting will be affected by the phenomenon of frame loss or scrambling because the camera is not synchronous. In this paper, using STC89C52 single chip microcomputer as the core controller, the synchronous signal controller is designed, and the trigger work and synchronization task of four cameras are realized. At the same time, the hardware composition and programming method of synchronous signal controller are analyzed in detail. (3) on the basis of MERUCURY software package, the function provided in the software package is analyzed, and the related functions are called by using Visual Studio 2010 design platform. A system software for real-time display of potato images collected by multiple cameras is developed, and the requirements for real-time display and acquisition of potato images are realized. In this paper, a potato hierarchical detection image acquisition system based on multi-CCD camera is designed, which realizes the synchronous trigger of multi-camera and ensures the surface information acquisition of potato as a whole. At the same time, the collected potato image can be displayed on the software interface of PC in real time. In this paper, the potato hierarchical detection image acquisition system based on multi-CCD camera provides important technical support for the accurate and rapid sorting of potato classification machine.
