COSCO SHIPPING Science & Technology applies for patents related to target detection methods, including day/night classification detection, to improve target detection accuracy and efficiency

March 28 news, the National Intellectual Property Administration information shows that China Ocean Shipping Technology Co., Ltd. has applied for a patent titled “Real-time Object Detection Method and System Based on Day and Night Classification and Adaptive Perception.” The application publication number is CN121725273A, the application number is CN202511713345.6, the application publication date is March 24, 2026, and the application date is November 20, 2025. The inventors are Han Zhuocheng and Liu Jun, the patent agency is Beijing Haihong Jiacheng Intellectual Property Agency Co., Ltd., and the patent agent is Gao Liping. The classification numbers are G06V10/764, G06V10/774, G06V10/82, G06V10/58, G06V10/56, G06V10/70, G06V10/766, G06V10/80, and G06N3/0464.

The patent summary shows that this invention relates to a real-time object detection method and system based on day and night classification and adaptive perception. First, it obtains the visible light images to be tested and historical images, scales them to a preset size, and converts them to the HSV color space. It combines the calculated average brightness, the proportion of low-brightness pixels, and saturation statistical features to determine day and night. If it is a daytime scene, it introduces the EIoU loss function and GhostConv lightweight module based on the YOLOv12 network model to construct an improved YOLOv12 network model and trains it with data augmentation strategies to obtain a trained daytime detection model. If it is a nighttime scene, it synchronously acquires infrared images from the same perspective, generates fusion-enhanced images by fusing visible light and infrared images through FusionGAN, and trains a nighttime detection model based on the fusion-enhanced images, effectively compensating for the loss of texture at night, achieving fast and efficient day and night recognition and low-latency determination, improving detection accuracy and robustness of targets in daytime images, as well as achieving accurate detection of nighttime targets.
