Embodiment Construction

[0017] The motion monitoring flowchart of the present invention is as figure 1 As shown, the following combination figure 1 Come to the specific implementation instructions. Motion monitoring of the present invention comprises the following steps:

[0018] (1) acquisition of target mice;

[0019] (2) Determination of the center of gravity, the position of the mouth and the root of the tail;

[0020] (3) Obtain motion trajectory information, including total distance, average speed, head orientation, total rest time and central area residence time.

[0021] First measure the actual length and width of the edge of the open field within the camera's field of view, which is recorded as a×b. For the same camera, the length of the length and width edges in the image increases year-on-year with the shooting height of the camera. Check the resolution of the camera, which is recorded as l×w, and 320×240 pixels are used in this experiment. in a l ...

Abstract

The invention relates to a method of mouse spontaneous behavior motion monitoring and posture image recognition, which designs an algorithm for recognizing three key points of a mouse mouth part, a mass center and a tail root part and establishes the corresponding recognition program. The method comprises the following steps: firstly, obtaining the object mouse; secondly, determining the mass center, the mouth part and the tail root part; thirdly, obtaining the motion track information; fourthly, judging the mouse inclines or not according to the result obtained by the step 2, entering the step 6 if inclining, or else entering the step 5; fifthly, detailing three statuses of squat, normal status, and extending through the posture ratio, and finishing; sixthly, detailing the inclining posture and finishing. The invention can accurately describe the motion status of the mouse, primarily realizes the posture recognition of the mouse, and riches the obtainable information of an automatic monitoring system.

Description

technical field [0001] The invention relates to a method for motion monitoring and body image recognition, in particular to a method for mouse spontaneous behavior motion monitoring and body image recognition. Background technique [0002] Under the influence of drugs, poisons and various external physical factors, whether the activity frequency, range of activities, memory, etc. of animals have changed due to the influence of these external factors requires observation of changes in animal activities to judge. Traditional behavioral research mainly relies on the researchers' visual observation and qualitative judgment. Subjective factors have a great influence, and many parameters cannot be quantified, which is time-consuming and labor-intensive. Subsequently, with the photoelectric technology being widely used in the detection of spontaneous activities, combined with the application of computers, a variety of monitoring devices have been produced, but there are few detecta...
