Street Squatting Detection

Algorithm Introduction
Leveraging AI vision algorithms, this solution focuses on nighttime road and curb scenarios, accurately identifying squatting pedestrians (particularly intoxicated individuals). It outputs bounding boxes and counts of squatting individuals, helping to control the volume of police incidents and reduce personal and property losses for citizens.
- ● Brightness Requirements: The overall brightness ratio of the image (proportion of bright pixels/regions to total pixels) must not be lower than 50%. Bright pixels are defined as having a grayscale value greater than 40.
- ● Image Requirements: Optimal detection performance is achieved at a resolution of 1344×768.
- ● Target Size: For standard 1080p (1920×1080) video streams, the minimum detectable target size is 60×120 pixels, and the maximum detectable target size is 512×512 pixels.
Application Value
-
Urban Roadways
Using AI vision algorithms, the system continuously monitors urban roads in real time for individuals squatting; once detected, it promptly issues alerts for potential traffic hazards to safeguard the safety of pedestrians and vehicles. -
Night Market/Food Stall Areas
The AI algorithm accurately identifies individuals squatting or sitting in the noisy and complex environment of night markets, thereby preventing disputes and stampede hazards, and maintaining order during nighttime operations.
FAQ

Algorithm AccuracyAll algorithms published on the website claim accuracies above 90 %. However, real-world performance drops can occur for the following reasons:
(1) Poor imaging quality, such as
• Strong light, backlight, nighttime, rain, snow, or fog degrading image quality
• Low resolution, motion blur, lens contamination, compression artifacts, or sensor noise
• Targets being partially or fully occluded (common in object detection, tracking, and pose estimation)
(2) The website provides two broad classes of algorithms: general-purpose and long-tail (rare scenes, uncommon object categories, or insufficient training data). Long-tail algorithms typically exhibit weaker generalization.
(3) Accuracy is not guaranteed in boundary or extreme scenarios.
