Abstract

The invention relates to an online measurement method for body size of living Simmental cattle based on a 3D camera, and the method comprises the steps: obtaining the three-dimensional image data of acattle body through a TOF camera, and converting the three-dimensional image data of the cattle body into the three-dimensional point cloud data of the cattle body; processing the cattle body three-dimensional point cloud data by using conditional filtering, statistical filtering and voxel filtering; performing clustering segmentation on the filtered cattle body three-dimensional point cloud databased on a random sampling consistency algorithm and an Euclidean clustering algorithm; performing curved surface reconstruction on the cattle body three-dimensional point cloud data obtained in theprevious step to obtain a complete cattle body curved surface model; on the reconstructed cattle body curved surface model, selecting body size measurement points according to a preset selection condition to obtain seven-item body size data corresponding to the cattle body; correcting the seven-item body size data by utilizing a correction function; according to the method, accurate measurement ofseven body size data of the cattle body is realized, and non-contact measurement of the body size of the living Simmental cattle is realized.

Description

technical field [0001] The invention relates to the technical field of cattle body measurement based on a 3D camera, in particular to an online method for measuring the body size of a living Simmental cattle based on a 3D camera. Background technique [0002] With the development of science and technology, 3D reconstruction and point cloud processing technology has become more popular. Most of the existing point cloud acquisition equipment for body measurement technology is laser scanner, but the structure of laser scanner is relatively complicated. It is difficult to popularize, and the operation of the measurement site directly affects the density of point cloud data, which is likely to bring great inconvenience to the later data processing. [0003] Therefore, how to avoid the inconvenience caused by later data processing and realize non-contact measurement has become an urgent problem to be solved by practitioners in the same industry. Contents of the invention [000...
