The structure of the grain placing tray 11 is explained below with reference to fig. 2 to 6. As shown in FIG. 2, the overall structure of the wheat grain placing plate comprises an upper cover plate formed by splicing a plurality of placing plates 113, and the upper cover plate is covered on the accommodating box 111. Each placing board 113 has a front side image hole 1131 and a back side image hole 1132. Wherein the grain accommodating boxes 112 are placed on the front image holes 1131 of each placing plate 113.

The principle of the invention for collecting the front and back images of wheat grains is illustrated by figures 7-8. By the lighting of the top major light 1, the camera 2 can obtain the front image of the wheat grain 12 in each wheat grain containing box 112. Meanwhile, because the wheat grain accommodating box 112 is made of transparent material, the back image of the wheat grain 12 can be polished by the back-side polishing lamp 14, and the back image of the wheat grain 12 is reflected to the camera device 2 through the prism group 114 and the transparent glass 115 in sequence. The tilted sides of each prism of the triple prism set are perpendicular to each other. Therefore, the imaging device 2 can obtain clear images of both the front and back surfaces of each grain 12 and perform image analysis.
The manner in which each grain 12 is weighed is illustrated below by FIG. 8. Each grain accommodating box 112 has support bars 1122 at both sides, and the support bars 1122 are supported on the weighing devices 13 by springs, and the weighing devices 13 are disposed on bosses 1133 of the placing plate 113. Therefore, with this configuration, the weight of each grain can be acquired simultaneously with acquiring the reverse image of the grain.
The corresponding wheat grain weight obtained by the weighing devices 13 and a picture with wheat grain images on the front side and the back side obtained by the camera 2 are transmitted to a computer processing system through a data transmission line.
The computer processing system first numbers the weight data according to the position of the weighing sensor 13 on the grain placement tray 11, and simultaneously segments the image acquired by the camera according to pixels. Since the position of each placement board 113 on the kernel placement tray 11 in the image is relatively fixed, the pixel division of the image is directly divided according to the division of the placement board 113, and the division is numbered. The image numbers correspond to the weight numbers one by one, so that the weight data of each wheat grain corresponds to images on the front side and the back side of the wheat grain.
The computer processing system prestores the standard wheat grain weight range of the wheat grain of the variety. And comparing the weight data of each wheat grain with the weight range of the standard wheat grain, and screening out the wheat grain numbers which are not in the weight range of the standard wheat grain. And then, an image identification module of the computer processing system identifies only the image corresponding to the wheat grain number which is not in the standard weight range. The abnormal type of the wheat grains with the non-standard weight is identified by comparing the image with images of several common wheat grains prestored by a computer, wherein the images of the common wheat grains are wormhoozed, damaged, germinated and mildewed. And carrying out statistics on each disease and damage to obtain the multi-parameter quality index of the wheat.
1. The weight of a single wheat grain is detected and compared with a standard value, and only the wheat grain image with non-standard weight is identified, so that the calculated amount of computer image identification is greatly reduced, and the detection time is shortened;
2. by arranging the front and back image holes of the placing plate and the triple prism group, the upper camera can simultaneously acquire images of the front and back surfaces of the wheat sample, so that the detection accuracy of the wheat sample is improved, and meanwhile, the components are simplified by utilizing the characteristics of light refraction, reflection and the like, so that the device is more compact in structure and the cost is reduced;
3. the wheat grain containing box is made of transparent materials, and the supporting rods are arranged on the two sides of the wheat grain containing box, so that the wheat grain containing box has the functions of containing wheat grains, weighing weight and reflecting images on the back of the wheat grains;
4. the weighing device is integrated in the front image hole of the wheat grain placing plate, and the transparent glass is arranged on the back image hole, so that the wheat grain placing plate has the functions of weighing and double-sided imaging, and the transparent glass can penetrate through the image and prevent the wheat grains from falling off;
5. the back surface of the placing plate is also provided with a lighting lamp, so that the image on the back surface of the wheat grain can clearly enter the camera lens through the refraction of the prism group, and the definition of the image and the identification accuracy are improved;
