Embodiment Construction

[0039] The present invention will be described in detail below in conjunction with specific examples:

[0040] A device for screening the number of silkworm cocoons in a grid cluster based on image processing, comprising: a bench, a workbench, a grid cluster, and a CMOS camera; the bench is used to support the workbench; the CMOS camera is fixed on the workbench through a bracket, so that Its lens hangs directly above the workbench and can take pictures directly to the workbench. The grid cluster is located under the CMOS camera, and ensures that the CMOS camera can completely capture the image of the grid cluster.

[0041] A method for screening silkworm cocoons based on image processing, the steps are as follows:

[0042] 1. Use a CMOS camera to collect images of the lattice cocoon.

[0043] 2. Set the threshold L 0 , Binarize the collected original square cocoon image, and the gray value exceeds the threshold L 0 The pixels of are judged as the target area, so as to obt...

Abstract

The invention provides a checker cocooning frame silkworm cocoon screening device and method based on image processing. The device comprises a rack, a working table, a checker cocooning frame and a CMOS camera. The CMOS camera is fixed to the working table through a support, and the checker cocooning frame is located below the CMOS camera. Accordingly, automatic checker cocooning frame silkworm cocoon counting and screening are conducted by combining an image processing technology, the CMOS camera is used for extracting the collected image by means of a binaryzation and corrosion division algorithm and region characteristics, checker cocooning frame silkworm cocoon pictures are processed, and silkworm cocoons are separated from the checker cocooning frame effectively; by marking target connected domains and counting the number of the target connected domains, the number of the silkworm cocoons is obtained, and characteristic extraction is conducted by means of area descriptors of all target connected domains; by means of judgement on the connected domain area, bad cocoons such as double cocoons and extra small cocoons are distinguished, and the counting effect is accurate and rapid.

Description

[0001] (1) Technical field [0002] The invention relates to an image processing-based screen cocoon screening device and method. [0003] (2) Background technology [0004] Grid sacks have become the widely used sacks in sericulture production in my country, especially cardboard grid sacks are the most widely used. With the extensive use of grid sacks, many automatic cocoon harvesting equipment for grid sacks have been developed successively. However, these devices are complex in structure and low in automation. Palace cocoons, extra small cocoons and other bad cocoons. The common method of collecting silkworm cocoons in the grid is still the traditional manual cocoon picking. After picking, the quantity statistics and the screening of bad cocoons are carried out. The efficiency and accuracy of statistical screening are low. Happens from time to time. Therefore, it is necessary to develop an efficient and high-precision silkworm cocoon collection device and system, so that ...
