【Abstract】 Applying YOLO(You Only Look Once) real-time object detection network to detection tasks in vehicle camera videos. Aiming at the low robustness due to environmental impact, and low performance of small object detection of present algorithms, a dataset containing multiple weather condition samples and Difficult Samples is established. The method of training Difficult Label is proposed. A YOLO model capable of well recognizing small cars, pedestrians, buses, and trucks in complex driving environment is trained, with high Recall rate and Precision, which can effectively improve detection performance and be primarily applied to real-time detection in vehicle camera videos.更多还原
