| Abstract: | In this paper, by analyzing the features of the serial images and the motion law of seed objects, a detection method to quality of the seed metering based on the seed serial of images is proposed. The method consists of the computation of the initial speed of seed and the time for seed's leaving the mouth of the seed metering, the coordinates translation of space position, getting the time interval of grabbing an image, recursively registering the 3D points in the serial of images, calculating the space distance between the seeds in horizontal direction, establishing statistical model of detection the seed metering, and so on. Consequently, the kind of eigenvalues of the seed distributing was obtained. The experiments show that the measurement results of the system are accurate and the detection speed of the system is fast. |
