O maze video analysis system
The O maze (referred to as Zero Maze in the literature) divides a ring-shaped area into four equal parts, alternating with high guardrails and no guardrails. The number of times of entering the danger zone is quantified to compare the degree of anxiety (derived from the nature of seeking advantages and avoiding disadvantages and the desire to explore the unknown) among different individuals. The O maze (zero maze) is a relatively new method for conducting anxiety research with reliable results. This product uses video tracking technology to complete the automation and quantification of the maze (zero maze) experiment, and the results are more real, credible and objective.Pre-consultation

1. Hardware parameters:
1. Zero maze rat: the diameter of the outer ring is 1000 mm, the width of the arm is 100 mm, and the height of the arm is 300 mm.
2. Zero maze mice: outer circle diameter 500 mm, arm width 60 mm, arm height 150 mm,
3. The height of the base from the ground: 500 mm
4. Material: industrial grade aluminum profile and special medical ABS engineering board
5. The O-maze (zero-maze) structure conforms to the domestic and foreign setting standards, and has the experimental environment of rats and mice, and is mainly used to measure the anxiety behavior of animals.
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, the software is allowed to work on laptop computers, supports online and offline video analysis, and facilitates statistics of data indicators;
9. Data indicators: time, distance, entry times of each area, activity percentage of each area, trajectory map, heat map.
