The present invention relates to a method for evaluating the swimming training state of a small animal, which can evaluate the swimming training state of a small animal such as a rat.
Fig. 1 shows a schematic configuration diagram of a small animal swimming training state evaluation system of the present invention. Fig. 2 shows a schematic longitudinal sectional view of the small animal swimming training status evaluation system of the present invention. As shown in fig. 1 and 2, the small-animal swimming training state evaluation system of the present invention includes a swimming pool 1. The swimming pool 1 contains water in which small animals such as mice and the like perform swimming training.

Therefore, the water level of the swimming tank 1 can be controlled and kept constant, so that the small animals can be ensured to carry out swimming training in constant-temperature water, and the influence on the swimming training state of the small animals caused by temperature difference is avoided.
The left side and the right side of the swimming tank 1 are respectively provided with a wide-angle camera 5. The two wide-angle cameras 5 are used for shooting swimming training videos of the small animals in the swimming tank 1.
Due to the adoption of the two wide-angle cameras 5, as shown in fig. 3 and 4, all swimming areas in the swimming pool 1 can be shot without dead angles.
The upper part of the swimming tank 1 is provided with a touch display screen 7 and a power switch 8. A controller is arranged in the touch display screen 7. Wherein the power switch 8 is used to determine whether to supply power to the touch display 7, the heating device 9, the controller, etc.
And the wide-angle camera 5, the touch display screen 7, the heating device 9 and the temperature sensor 11 are connected with the controller. Thus, the controller can control whether the heating device 9 is activated or not based on the detection result of the temperature sensor 11.
Simultaneously, the controller is still used for assessing the swimming training state of the small animal based on the shooting videos of the two wide-angle cameras 5. The touch display screen 7 is used for displaying the swimming training state of the small animal and the evaluation result of the swimming training state
Preferably, the bottom of the swimming pool 1 is also provided with a filter screen 3. The filter net 3 is used for separating the inner space of the swimming tank 1. When the swimming training device is used, the small animals carry out swimming training in the space above the filter screen 3, and foreign matters such as excrement of the small animals are located in the space below the filter screen 3, so that the foreign matters such as the excrement of the small animals cannot influence the swimming training of the small animals.
More preferably, the bottom of the swimming pool 1 is provided with a moving support 2. The swimming pool 1 is detachably placed on the moving support 2. The lower portion of the moving bracket 2 has a plurality of moving wheels. Thus, the swimming tank 1 is more convenient to move, and is convenient to move to a proper position for swimming training of the small animals.
When the small animal swimming training state evaluation system is used for evaluating the small animal swimming training state, the method mainly comprises the following steps:
firstly, two wide-angle cameras 5 are adopted to shoot swimming training videos of the small animals in the swimming tank 1 respectively.
As shown in fig. 3 and 4, since the two wide-angle cameras 5 are adopted in the invention, and the two wide-angle cameras 5 are respectively located at two sides of the swimming pool 1, all swimming areas in the swimming pool 1 can be shot without dead angles, and complete shooting in the swimming training process of small animals can be ensured.
Secondly, splicing the swimming training videos of the small animals in the swimming tank 1 respectively shot by the two wide-angle cameras 5 by adopting a real-time full-automatic video splicing method to obtain the real-time videos of the swimming training of the small animals.
Since a single wide-angle camera 5 cannot completely shoot the swimming training process of the small animal, the swimming training videos of the small animal in the swimming pool 1 shot by two wide-angle cameras 5 must be spliced to obtain the complete video of the swimming training of the small animal.
In the invention, a real-time full-automatic video splicing method can be adopted to splice the swimming training videos of the small animals in the swimming tank 1 respectively shot by the two wide-angle cameras 5.
Specifically, in the splicing process, an image splicing technology based on SIFT features is adopted by taking the frame of the swimming pool 1 as a reference.
More specifically, the initial frames of the videos captured by the two wide-angle cameras 5 are geometrically corrected with the frame of the swimming pool 1 as a reference, so that the captured images conform to the actual shape and size; then, extracting the characteristics of the initial video frame based on an SIFT (Scale-invariant feature transform) algorithm, detecting key characteristic points of images acquired by the two wide-angle cameras 5, and further screening and optimizing the characteristic points by using an RANSAC algorithm; and finally, calculating the relative offset vector of the two images according to the feature point matching result, and compensating the offset vector to realize the image splicing of the two wide-angle cameras 5.
And splicing other videos to process subsequent images in real time according to the splicing algorithm of the initial frame.
And then, identifying the small animals in the swimming tank 1 by adopting a video image multi-target tracking technology in the spliced real-time video of the swimming training of the small animals, tracking the swimming tracks of the small animals in real time and recording the swimming track data of the small animals based on a time sequence.
After a real-time video of the swimming training of the small animal is obtained, the small animal in the video needs to be identified and tracked to obtain the swimming track of the small animal and record the swimming track data of the small animal based on the time sequence.
In the invention, the steps of identifying the small animal in the swimming tank 1, tracking the swimming track of the small animal in real time and recording the small animal swimming track data based on the time sequence are as follows: each small animal was marked on its back using a different color card. The color card is a standard card and its color is recorded in the controller. Thus, the controller can distinguish different small animals according to the color information and the small animal shape information. Meanwhile, each small animal can be numbered independently. In this way, the positions of the small animals in each frame of image are recorded, and the positions of the small animals with the same number in each frame of image are connected to form the motion trail of each small animal. And the small animal swimming track data based on the time sequence can be obtained by recording the position of each small animal in each frame of image.
And finally, analyzing the movement rate of the small animal at different time points and the swimming distance of a single small animal based on the identification result of the small animal, the swimming track of the small animal and the swimming track data of the small animal based on the time sequence, and calculating the movement amount, the movement state and the energy consumption of the small animal, thereby evaluating the swimming training state of the small animal.
Wherein the moving speed is dD/dt, namely the moving distance in unit time (1 s). The amount of motion of the small animal is its total swimming distance during a single swimming session. The movement status of the small animals at each time point was assessed according to the movement rate. The movement of the small animal is divided into an active movement state and a passive movement state according to different movement rates (for example, the movement rate is more than 15 cm/s is an active state, and less than 15 cm/s is a passive state). And taking the time ratio of the active motion state to the passive motion state as an index for evaluating the overall motion state of the small animal. The energy consumption level of the swimming movement of the small animal is calculated according to the total swimming distance and the movement state. Specifically, energy consumption amount (cal) = 4 × active exercise time(s) × body weight (kg) + 2 × passive exercise time(s) × body weight (kg).
In the evaluation process, the swimming training state of the small animal and the evaluation result of the swimming training state, such as swimming training time, water temperature, and the small animal exercise training evaluation result (including exercise amount, exercise rate, exercise state, energy consumption, etc.), can be displayed through the touch display screen 7
Meanwhile, in the evaluation process, according to the detection result of the temperature sensor, the water in the swimming tank 1 is heated through the heating device 9 to keep the water in a constant temperature state, and different temperatures can be set according to different small animals, so that the temperature of the water can be controlled.
The above examples of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. It is not exhaustive here for all embodiments. Obvious changes and modifications of the technical scheme of the invention are included in the protection scope of the invention.
