Embodiment Construction

[0044] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0045] According to the scheme in the above-mentioned invention, in the specific implementation process such as figure 1 As shown, first we use two railings to mark out a dedicated channel, and set up a weighbridge in the center of the channel. Limit bars are set up at the entrance and exit of the channel to limit the movement of cows. The channel between the two limit rods is the measurement space 5, the front end is equipped with an identification device 1, and cameras (2, 3) are respectively installed directly above and on the side of the channel. The console 4 is at a distance from the measurement space, and a computer and an electrical control box (not shown in the figure) are installed. The computer is respectively connected with the ide...

Abstract

The invention discloses a method for measuring and acquiring body image data of a dairy cow in combination with multimedia image shooting and computer processing. In the method, the problem of body data acquisition of a dairy cow is solved by an image measuring method without contacting a dairy cow individual so that the stress reaction of the dairy cow to a stranger is avoided and damages of thedairy cow to measuring personnel can be prevented. Simultaneously, practical measurement of the image method is completed off line so that the time of a data acquisition process is much shorter than that of the conventional common manual measuring method. Moreover, the dairy cow moves little in a data acquisition period so that effect on a measuring result is small. The subjective factor of the conventional manual measurement has large effect on the measuring result while the image method is more objective and has higher data repeatability and correctness. Data obtained by the image method can be directly saved in a digital system in the form of database so that error caused by manual secondary input is avoided and contribution to digital management of a dairy farm is made.

Description

Technical field: [0001] The invention relates to a method for image measurement combining multimedia images and computers, in particular to an image measurement and acquisition method for dairy cow body data. Background technique: [0002] The goal of dairy cow production is high yield, stable yield, health, and longevity, and the purpose of studying the physical appearance of dairy cows is to reveal the relationship between appearance, production performance and health, so as to select high-yield, stable yield, and healthy dairy cows as much as possible. of cattle. Practice has proved that through scientific appearance identification technology, cattle with better physique and appearance identified generally have higher production performance. Therefore, in the breeding work of dairy cows, in addition to paying attention to the milk production performance of cows, countries also attach great importance to the physical appearance of dairy cows. And weighing can accurately ...
