Problems solved by technology
[0003] However, the depth camera is expensive, and due to cost considerations, it is usually only possible to use the monocular camera installed on the top of the cowshed. The ceiling camera is in a vertical shooting state. Due to the incomplete overlooking information, it is difficult to accurately estimate the lying position of the cow.

Embodiment Construction
[0048] In this embodiment, the method and system for estimating animal posture with a monocular camera and the computer-readable storage medium are taken as examples, and the present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.
[0049] see figure 1 , figure 2 and image 3 , showing a method for estimating animal posture based on a monocular camera provided by an embodiment of the present invention, including the following steps:
[0050] Step 1, install a monocular camera and control the predetermined height H from the ground;
[0051] Step 2, measure the height h of a standard cow when standing 0 , and calculate the body area s of the standard cow when standing by the monocular camera 0 ;
[0052] Step 3, identify and calculate the body area s of the target cow in the image captured by the monocular camera x ;
[0053] Step 4, according to the ratio between the body area of the cow and the height of...

The invention discloses a method and system for estimating animal posture based on a monocular camera and a computer readable storage medium, and the method comprises the following steps: installing the monocular camera, and keeping a distance from the monocular camera to the ground by a preset height H; measuring the height h0 of the standard cattle when the standard cattle stands, and calculating the body area s0 of the standard cattle when the standard cattle stands, which is shot by the monocular camera; identifying and calculating the body area sx of the target cattle in the image shot by the monocular camera; calculating the height hx of the target cattle according to the ratio of the body area of the cattle to the height of the cattle; and judging the posture of the cattle according to the height hx of the target cattle. The monocular camera is used for monitoring the health condition of the cattle, the installation method is simple, and the production cost is reduced.
Description
technical field [0001] The invention relates to the technical field of livestock breeding monitoring, in particular to a method and system for estimating animal posture based on a monocular camera and a computer-readable storage medium. Background technique [0002] In the process of raising cattle, the lying down of the cattle is one of the important indicators to monitor the health of the cattle. The cattle only have two states of standing and lying down. The cattle cannot lie down for a long time, which is one of the first signs to judge whether the cattle are sick. . The depth camera has a depth detection function, which can use the principle of parallax to obtain the depth of the target object, and use the depth camera to detect the state of the cow to initially judge the health status of the cow. [0003] However, the depth camera is expensive, and due to cost considerations, it is usually only possible to use a monocular camera installed on the top of the cowshed. Th...
