Abstract

Currently, the mainly used methods for corn parameters are traditional artificial method and semi-automatic method based on machine vision technology, which restrict the efficiency of multiple date acquisition during corn breeding. To solve this problem, an automatic testing system for corn was developed. This system is consist of corn ear testing unit, automatic threshing unit, corn kernels testing unit, post-processing unit and system control unit. Corn ear testing unit contains four cameras as well as a weighting sensor, which can measure corn ear parameters such as ear weight, ear length, ear width, ear row number, grains per row, bare tip size, et al. automatically. Corn kernels testing unit measures corn kernels parameters including kernel color, kernel width, kernel length, kernel shape, kernel number, et al. based on computer vision technology after kernels were spreading out by a vibrating mechanism. Post-processing unit can lift kernels to a fixed height, packaging the kernels and print a label contains corn ear and corn kernel parameters. An industrial control tablet combined with I/O module were chosen for the system control unit, receiving sensing information and feedback to control the device. Results of experiment showed that the prototype can realize the whole testing process for corn, includes ear parameters measuring, ear threshing, kernel parameters measuring, kernel lifting, kernel packaging and label printing automatically. The average efficiency of the prototype was up to 4 ear/minute, the average measurement accuracy for ear length and ear width is up to 98.93% and 97.71%, the average accuracy of kernel number is up to 99.11%, which can improve the efficiency of corn breeding obviously.
