Description

Animal behavior monitoring method and system thereof

The invention relates to an animal behavior monitoring method and system thereof, in particular to an animal behavior monitoring method and system for analyzing animal gait behavior by using a multi-touch panel.

According to, in the field of medical research such as physiology, psychology or pharmacology, researchers can use the animal behavior monitoring process to display physiological responses (such as breathing) through animals (eg, rodents, mice, etc.). Reactions such as actions) are known about their intrinsic physiological conditions (eg, the effects of drugs on animals), so how to effectively monitor animal behavior is closely related to the results of the above medical research.

Among the conventional animal behavior monitoring methods, such as: manual recording method, optical sensing matrix positioning method, ultrasonic sensing method, image sensing method or single touch sensing method, etc., respectively Description: The traditional manual recording method is to visually observe the changes in animal behavior by the researchers and record them in a textual manner. However, the conventional manual recording method is not only inefficient and the measurement results are not objective.

The light sensing matrix positioning method and the ultrasonic sensing method are densely arranged with a light sensor and an ultrasonic sensor respectively, and the positions of the animals are known from the output of the sensors; however, due to cost considerations The set density of the sensors is not high, resulting in limited accuracy of the measurement results, and the output of the sensors can only guess part of the behavior of the animal (for example: standing or moving behavior), not only easy Twins misjudged animal behavior and were unable to analyze animal gait behavior.

The conventional image sensing method uses a camera to record images of animal behavior, and uses software to perform image recognition and analysis to determine the orientation, range of motion, and walking trajectory of the animal; however, the image recognition result is affected by the image quality. Huge, and the quality of the image will be affected by many factors such as the environment, light source, animal color, background contrast and shooting angle when the image is captured. If the image quality is poor, it will not only increase the chance of image recognition error, but also Need to be supplemented by manual visual analysis, increasing labor and time costs; in addition, rodent animals are often used as experimental animals in animal behavior monitoring. Because these animals are mostly nocturnal animals, when observing animal behavior, they need to be in the dark room. In the darkroom, in the darkroom, if you use low-light photography, it will increase the difficulty of image capture and analysis. However, if you take light photography, it will affect the animal behavior. Therefore, the accuracy of the conventional image sensing method is monitored. limited.

The conventional single-touch sensing method uses a single-touch panel to sense the movement of the center of gravity when the animal crawls, and uses the center of gravity movement as the basis for recording the movement track of the animal. However, there are still many shortcomings in this method that need to be overcome:

1. If the experimental animals are quadruped (eg, large, mouse, etc.), such animals often maintain a two-legged standing position when exploring the environment or eating. At this time, the single-point trackpad can only sense animals. The situation in which the center of gravity moves, and the magnitude of the movement of the center of gravity determines whether the animal has a standing behavior, and it is easy to cause a misjudgment of the behavior of the animal.

2. When a single touch panel (for example, a resistive touch panel) senses the movement of the animal's center of gravity, the single point pressure must exceed a certain value (for example: 200 grams) to detect the position of the animal's touch point. When a quadruped animal walks on a single touchpad, it often fails to detect changes in the animal's position due to pressure dispersion.

Third, the single-touch panel can only record the movement trajectory of the animal, and can not obtain the footstep information of the animal when walking, for example, the position of each step, etc., therefore, it is not suitable for gait/locomotion analysis of animals. ).

In summary, in addition to the inability to perform "gait analysis", the conventional animal behavior monitoring method has doubts about "false positive animal behavior" when conducting monitoring. In actual use, it has different limitations and shortcomings. It is inconvenient. Where improvements are needed, further improvements are needed.

Searching for a maximum contact area value in the contact area of the group, and determining whether the maximum contact area value is within a predetermined area range (for example, 20 to 50 pixels). If the determination is YES, the control module 2 Analyzing the footprint type of the contact parameter group, and recording the identification code of the contact parameter group as analyzed. If the determination is No, the control module 2 determines that the contact area of the contact parameter group is noise. And after recording the identification code of the contact parameter group as analyzed, the next contact parameter group is read.

Then, the control module 2 can distinguish the footprint type of the contact parameter group according to the relative spatial orientation of the position coordinates of the contact parameter group, for example: forward, backward, left or The right side (right) foot, etc.; in addition, the control module 2 can be distinguished from the stepping type of the animal A by the contact state of the contact parameter group having the same identification code, for example: early or earlier Stepping on the night.

The contact state is the end contact 〞, and the control module 2 calculates the difference between the time stamps T4 and T1, and the standing period T _{S of} the contact point P4 can be obtained. Therefore, the standing time of the remaining contact points P can be deduced by analogy.

In addition, in the process in which the animal A continuously steps on the sensing surface 11 with its four feet, if two contact points P are successively formed, for example, two contact points P of the "family side" are formed successively. The control module 2 can start the contact 〞 according to the contact state of the contact parameter group of the two contact points P, and the occurrence time of the contact 〞 is sooner or later (the instant stamp value is small and large), and the footprint types are opposite to each other and The types of pedaling that are successively formed in the contact parameter group are divided into early stepping pedals and evening pedaling.
