| Abstract_FL | Corn parameters measuring are an important step in corn breeding.Currently,researchers measure corn parameters manually or with the help of machine vision technology.The existing corn parameters measuring and methods mainly aim at corn ears or kernels rather than measuring them at the same time,which is difficult to meet the demand of rapidly measuring a large amount of breeding materials in the breeding process.To solve this problem,in this paper,a high throughput automatic measuring device for corn was designed and a prototype was developed.This device mainly included corn ear parameter measuring unit,automatic threshing unit,corn kernels parameter measuring unit,post-processing unit,and system control unit,which can realize the whole process such as ear parameters measuring,ear threshing,kernel parameters measuring,kernel lifting,kernel packaging and label printing automatically.A weighting sensor and four high-resolution color cameras were evenly distributed around the ear with the interval of 90 degrees to get the corn ear images in four directions to acquire corn ear parameters such as ear weight,ear length,ear width,ear rows,bare tip,et al.at the corn ear parameter measuring unit.The average measurement accuracy for ear length and ear width was up to 99.13％ and 99.21％.The Canadian Agriculex SCS-2 single ear corn thresher was chosen for automatic threshing unit.Efficiency of the thresher was up to 3-5 s/ear,which can meet the acquirements of high throughput processing.Corn kernels parameters such as kernel number,kernel average length,average width,kernel shape,et al.were obtained in corn kernel parameters measuring unit,which was designed and had three parts:1) image acquisition device used for kernel images acquisition;2) automatic spreading mechanism used for reducing kernel adhesion and accumulation,so as to obtain high-quality kernel images;and 3) kernel discharging mechanism used for ensuring the smooth implementation of high-throughput assembly line operation and letting the kernels discharged.The average accuracy of kernel number reached 99.39％.Post-processing unit can lift kernels from corn kernels parameter measuring unit to a fixed height and pack it with a printed QR code label which contained all corn ear and corn kernel parameters.A Kunluntongtai TPC7062K industrial control tablet and MODBUS relay control input-output module with 16 photoelectric isolating switch input channels and 16 photoelectric isolating relay output channels were chosen for the system control unit to receive sensing information and feedback to control the device.The results of experiment showed that the prototype can obtain information both for corn ear and corn kernels automatically.The average time consuming of the prototype for single corn processing was about 27.2 s,and the average efficiency was up to 4 ear/minute during continuous operation mode,which greatly improved the efficiency of corn breeding processes. |
