Abstract

The invention discloses an on-corncob corn niblet counting method and relates to the field of machine vision. The method comprises the steps of A, collecting a current gray level image of a corn panicle and processing the current gray level image to obtain a first processing area; B, finding a starting point of niblet row extraction in a first processing area; C, extracting a first corn niblet row in the first processing area according to the starting point; D, rotating the corn panicle and extracting a next corn niblet row; E, judging whether the current corn niblet row is the same with the first corn niblet row, if the current corn niblet row is the same with the first corn niblet row, eliminating the current corn niblet row and performing the step F; otherwise, performing the step D; and F, measuring the number of the corn niblets of all corn niblet rows sequentially to obtain a total number of all the corn niblets of the corn panicle. According to the method, a counting device with the high cost is not required, the implementation cost is low, the number of the the niblets of the corn panicle can be measured rapidly, accurately and stably, the detection method has the advantages of being flexible, good in timeliness and accuracy and the like.

Description

technical field [0001] The invention relates to the technical field of machine vision, in particular to a method for counting corn kernels in ears. Background technique [0002] Corn is a widely grown crop, and it is usually necessary to estimate its yield by sampling before harvesting. The number of kernels per ear and the weight of 100 kernels are important parameters for estimating the yield of corn. To obtain these parameters, it is necessary to count the number of corn kernels. In addition, in agricultural research such as corn breeding, cultivation, new variety testing, and quality evaluation, it is often necessary to count corn kernels or measure corn ear trait parameters (such as the number of ear rows, ear grains, etc.). The traditional method of counting corn grains is to thresh the corn ears, and then carry out manual visual inspection of the number of kernels, and also use manual visual inspection to measure the parameters of corn ear traits. This method is ine...
