Complexities in Elevator Object Detection
Elevator environments pose unique challenges for real-time object detection due to dynamic lighting, rapidly moving targets, and low-quality video frames. Critical issues include:
- False Positives & Missed Detections: Dense targets, such as multiple passengers and objects obstructing each other, often lead to errors.
- Detection Jitter: Inconsistent target counts in video streams caused by movement and temporary occlusions.
- Occlusion: Mutual occlusion between targets severely hinders accurate identification and localization.
- Varied Target Features: Similar appearances between adults and children, diverse clothing, and various objects make robust identification difficult.
- Complex Backgrounds: Advertising stickers, notices, and protective panels create cluttered backgrounds.
Existing YOLO models, while powerful, often struggle with these specific environmental factors, necessitating further algorithmic refinement for practical deployment on edge devices.
Innovative Algorithmic Enhancements
The research proposes a refined YOLOv8s-based algorithm to overcome the identified challenges, focusing on enhancing feature extraction and detection stability:
- Deformable Convolution Integration: Enhances the extraction of target features across different scales by allowing the convolution kernel to sample points with learned offsets, better adapting to target shapes and sizes.
- Occlusion Perception Attention Mechanism: Improves feature extraction for occluded targets. By combining global max pooling and global average pooling with a one-dimensional convolution and sigmoid activation, it emphasizes crucial target features while suppressing background noise.
- Jitter Smoothing Algorithm: Addresses target quantity jitter in recognition. This algorithm processes detection results within a sliding time window (e.g., 5 frames), smoothing fluctuations caused by target movement or transient occlusions to ensure a stable count.
These enhancements are designed to improve both precision and robustness without significantly increasing computational complexity, making the model suitable for edge device deployment.
Rigorous Experimental Validation
The proposed algorithm's efficacy was thoroughly validated against state-of-the-art models using a custom dataset of over 15,000 high-quality, multi-scene target images, expanded to 79,602 with data augmentation.
Comparative experiments with Faster R-CNN, Mamba-YOLO, YOLOv3, YOLOv5, YOLOv8, and YOLO11 demonstrated superior performance:
- Precision: Achieved 97.1%, surpassing all compared algorithms.
- Recall: Reached 96.1%, indicating strong ability to find all relevant instances.
- mAP50-95: Achieved 0.865, demonstrating robust performance across various Intersection over Union (IoU) thresholds.
- Small Target Detection: Showed significant enhancement in detecting small-sized targets, particularly children.
- Detection Speed: Deployed on RK3588S, achieving real-time detection at 35ms per frame, meeting practical engineering requirements.
These results confirm the algorithm's capability to better detect children and mutually occluded targets, with stable target quantity recognition, making it highly suitable for intelligent elevator monitoring.
