Below in conjunction with the accompanying drawing in the embodiment of the present application, be clearly and completely described the technical scheme in the embodiment of the present application, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the application's protection.
The plantar nervous arch index in the research of mouse gait analysis is proposed in plantar nervous arch acquisition methods in mouse gait analysis provided by the invention, plantar nervous arch index is a gait index that can reflect mouse health status, and plantar nervous arch index and normal rat as suffered from the mouse of the diseases such as foot have a great difference.By obtaining the plantar nervous arch index in mouse gait analysis, can judge whether mouse suffers from the disease of certain particular type, certain reference can be provided for kinematics, behavior analysis and pharmacodynamic assessment.
Below carry out the introduction of embodiment particular content.
Embodiments provide the plantar nervous arch acquisition methods in a kind of mouse gait analysis, the plantar nervous arch acquisition methods process flow diagram in a kind of mouse gait analysis provided for the present embodiment with reference to figure 1, Fig. 1, specifically can comprise:
S101: obtain mouse gait video data, and read in the view data in described mouse gait video data.
The embodiment of the present invention is the runway utilizing glass treadmill to test as mouse, arrange row's LED array along treadmill glass length direction at glass treadmill rear, wherein, LED direction of illumination is to glass treadmill internal irradiation perpendicular to glass treadmill cut surface, adjacent LED irradiation area covers mutually, is full of whole treadmill inside glass to make light.Usual LED selects red colored lamp or green light, and green light best results.Above mouse ambulatory activities space, install bias light lamp box, lamp box is parallel to treadmill glass, irradiates vertically downward.Background lamp box illuminating lamp color needs to cooperatively interact with treadmill LED color, and such as, during the selection such as LED red colored lamp, bias light lamp box illuminating lamp color selecting is blue; During LED selection green light, bias light lamp box illuminating lamp color selecting is red.Utilize backlight principle, collection camera is installed on below treadmill glass, takes vertically upward, obtain mouse gait video data.
At above-mentioned glass treadmill as under the enforcement scene of mouse testing track, when lab mice walks on glass treadmill, gather collected by camera to image on mouse health overlay area be black region, differ greatly with background area, be easy to identify segmentation.
The embodiment of the present invention does not limit the obtain manner of mouse gait video data, utilizes the collection camera be installed on below treadmill glass to obtain mouse gait video data only with a kind of implementation.
The embodiment of the present invention, after acquisition mouse gait video data, reads the view data in described mouse gait video data.Because mouse gait video data comprises some frame image datas, so the present embodiment is using every frame image data as process unit, carry out the body corner index selection of mouse.
