1. Enables footprint and gait recognition and analysis via video-based internal light refraction technology.
2. Capable of automatically identifying and classifying limb footprints and calculating relevant footprint and gait parameters.
3. Features a glass walkway with colored internal light sources and a length of≥120cm.
4. Equipped with a high-speed camera (frame rate≥100Hz) to capture the light flux refracted by the glass walkway. The camera is connected to the computer network card via UTP cable.
5. The camera can cover a walkway area of≥50cm and capture≥4 sets of rat footprints.
6. The walkway side walls are adjustable to accommodate the movement of rats or mice.
7. Comes with a lid that emits a colored background, enabling the software system to capture the animal's silhouette and improving the accuracy of automatic footprint recognition.
8. The system can operate under red light or low illumination conditions.
9. Allows interactive measurement of proximal and distal inter-toe distances, footprint length, and footprint orientation.
10. The software visualization provides various diagrams, including planar footprint diagrams, gait sequence diagrams, footprint pressure distribution diagrams, gait pattern diagrams, and 3D footprint diagrams.
11. Automatically saves video files with a resolution of≥640*480, 100 frames per second, and a recording duration of≥60 seconds.
12. Supports bidirectional analysis, enabling data collection and analysis for both forward and backward animal movement.
13. Offers two types of footprint and gait technical parameters: one based on individual footprints and the other based on the relationships between different footprints, which mainly reflects gait coordination.
