In the field of security, fisheye lenses—characterized by their ultra-wide field of view and distinctive imaging properties—have demonstrated significant technical advantages in surveillance systems. The following outlines their primary application scenarios and key technical features:
I. Core Application Scenarios
Panoramic Monitoring Coverage
Fisheye lenses offer an ultra-wide field of view ranging from 180° to 280°, enabling a single device to fully cover enclosed or confined spaces such as warehouses, shopping malls, and elevator lobbies. This capability effectively replaces traditional multi-camera setups. For example, 360° panoramic fisheye cameras, utilizing circular or full-frame imaging designs in conjunction with backend image correction algorithms, enable continuous, blind-spot-free monitoring.
Intelligent Security Systems
- Target Tracking and Pedestrian Flow Analysis: When mounted overhead, fisheye lenses significantly reduce visual occlusion caused by crowds, thereby improving the stability of target tracking. Additionally, they mitigate issues of duplicate counting commonly found in multi-camera systems, enhancing data accuracy.
- Visitor Management: Integrated with intelligent recognition algorithms, fisheye lenses (e.g., M12 models with a field of view exceeding 220°) support automated visitor registration, identity verification, and behavioral analysis, thus improving the efficiency and effectiveness of security operations.
Industrial and Specialized Environment Applications
Fisheye lenses are extensively employed in inspection tasks within confined environments such as pipelines and internal equipment structures, facilitating remote visual diagnostics and improving operational safety. Furthermore, in autonomous vehicle testing, these lenses enhance environmental perception in narrow roads and complex intersections, contributing to improved system responsiveness and decision-making accuracy.
II. Technical Features and Optimization Strategies
Distortion Correction and Image Processing
Fisheye lenses achieve wide-angle coverage through intentional barrel distortion, which necessitates advanced image processing techniques—such as equidistant projection models—for geometric correction. These methods ensure that linear structure restoration errors in critical regions remain within 0.5 pixels. In practical surveillance applications, image stitching is often combined with distortion correction to generate high-resolution, low-distortion panoramic views suitable for detailed monitoring and analytical purposes.
Multi-Lens Collaborative Deployment
In unmanned aerial vehicles (UAVs) or vehicular monitoring platforms, multiple fisheye lenses (e.g., four M12 units) can be synchronously operated and fused to construct seamless 360° panoramic imagery. This approach is widely applied in complex operational contexts such as agricultural remote sensing and post-disaster site assessment, significantly enhancing situational awareness and spatial understanding.
