Video Analysis System of Rotation Experiment

Description Parameters Resources

For the determination of spontaneous or drug-induced rotational behavior in rodents, it is particularly beneficial for the study of (6-hydroxydopamine) Parkinson's and models of brain and spinal cord injury. In the experiment, the animals move on a special experimental table, and the circular arc design ensures that the animal's movement is not restricted by any direction. The software can automatically measure the change of the animal's rotation direction through the camera.

The Zhongshi Technology Cycling Tester is a computer-controlled system designed to analyze the cycling behavior of rodents with unilateral brain injury. The animal is attached to a rotation sensor and can move unrestrictedly within a purpose-built unit. This sensor monitors the total number of revolutions, clockwise or counterclockwise, with a resolution of 1/250 of a revolution

1. Hardware parameters:

1. Number of simultaneous analysis channels: 16

2. Sampling rate: maximum 25fps

3. Image resolution: 640*480

4. Dimensions of the experimental platform: inner diameter: 460mm, outer diameter: 590mm, elevated height: 500mm

2. Camera parameters:

1. Camera: gun type

2. Color: color/black and white

3. Camera resolution ≥640*480

4. Camera adapter power supply: DC 12V

5. Camera type: 2.8---12mm zoom

3. Software parameters:

1. One-click drawing area

The labmaze center fixed-point drawing method is convenient to draw the labyrinth area required for the experiment. After the experiment, it is found that a certain area is not drawn, and this area can be temporarily added without re-analyzing the video. The software can directly obtain the indicators of this area.

2. Intelligent AI algorithm

The software automatically recognizes the volume and shape of animals by learning and extracts them from complex backgrounds. It has strong anti-interference ability and filtering ability. Even if there are many ripples that interfere with the picture, it can accurately track animals.

Tracking method: The tip of the nose, the center, and the root of the tail track three points and analyze the data corresponding to the three points at the same time, etc.

3. Diversified experimental process design

The software is openly edited for conditions such as time, area, speed, hardware, steps, events, etc., which is convenient for editing the experimental process mentioned in any literature.

4. Human-computer interaction verification

The software automatically saves the experimental process video, and the experimental video and analysis indicators can be played back simultaneously with the same window, verifying the unity of software analysis and manual calculation, and ensuring the authenticity of the analysis results.

5. Rich statistical indicators

The software can analyze more than 200 indicators such as visit times, stay time, percentage, moving distance, speed, rotation between regions, trajectory diagrams, time series diagrams, heat map, and event relationships of each quadrant or area;

6. GLP management

The software has the function of rights management, the administrator assigns the experimental user account and manages the user rights; reviews the operation of the experimenter

7. Strong compatibility and scalability

Strong compatibility: It can be used as a platform with similar products of other brands at home and abroad. It is convenient to expand and upgrade the platform in the future, and the secondary expansion software will no longer cost;

8. The software is allowed to be installed on multiple computers, supports online and offline video analysis, and facilitates data indicator statistics;

9. Main observation indicators: time period (s), name, grouping, total time (s), number of clockwise laps, clockwise lap time (s), counterclockwise laps, counterclockwise lap time (s), number of direction changes , The number of steering angles can be set, the data can be queried by time period, motion track and video recording
