Abstract

The invention discloses a rail transit obstacle avoidance system based on image processing and target recognition. The rail transit obstacle avoidance system comprises a data acquisition module, an artificial intelligence processing module and a display control module; a collected image is segmented through the artificial intelligence processing module, so that the train running track can be marked quickly and accurately, and the warning area can be divided more accurately; obstacle detection is carried out through a millimeter-wave radar to obtain orientation and distance information of the target; targets such as personnel, vehicles and trains in the collected images are recognized through the artificial intelligence processing module, target image coordinates are obtained and fused withradar data, whether obstacles exist or not is comprehensively judged, and an alarm is given if the obstacles are in a warning area. The video data can be uploaded to the display control module in real time through the Ethernet. Image segmentation is carried out on the rail, so that warning area division is more accurate; and through image target identification and radar detection, the target identification accuracy can be effectively improved, the false alarm rate is reduced, and the alarm accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of visual obstacle avoidance, in particular to a rail transit obstacle avoidance system based on image processing and target recognition. Background technique [0002] Image processing and target recognition is an important field of artificial intelligence, which refers to the technology of processing, analyzing and understanding images to identify various types of targets and objects. Image-based target recognition needs to roughly go through several steps such as image acquisition, data enhancement (such as rotation, flipping, cropping, adding noise, etc.), model training, segmentation, and recognition. Compared with the traditional expressway, the environment of rail transit has its uniqueness, especially the intersection of multiple railroad tracks, and the traditional recognition algorithm is easy to mistakenly identify the targets on other tracks. [0003] In the traditional rail transit signal system...
