Spatial Displacement Change

## Spatial Displacement Change

## Module Principle
Detects the amount of displacement that occurs when a target moves away from a specific reference position.

## Usage Scenarios
Used for AI-SOP (Standard Operating Procedure) to capture signals indicating changes in spatial position.

## Parameter Configuration Description
*   **Detection Frame Count:** The window size (number of frames) used for detection.
*   **Movement Direction:** Currently supports movement in four directions: Positive X-axis, Negative X-axis, Positive Y-axis, and Negative Y-axis.
*   **Displacement Threshold:** The minimum amount of displacement required to be considered a valid change.
*   **Minimum Displacement:** The minimum effective value for each displacement event, used to filter out micro-movements and prevent interference.

## Input Description
*   **Reference Point:** A controlled benchmark point that needs to be set.
*   **Center Position:** The center position of the target being detected.

## Output Description
*   **Run Result:** Indicates whether the module is currently running.
*   **Displacement Change Result:** Outputs a `true` pulse signal when a displacement meeting the specified conditions is detected.
*   **Cumulative Displacement:** Displays the real-time observed changes in displacement, primarily used for debugging purposes.
