Embodiment Construction
[0044] The present invention will be further described in detail below with reference to the drawings and embodiments.
[0045] Based on the vehicle detection technology, the invention realizes the detection and identification of the emergency vehicle by performing triple feature extraction and matching on the emergency vehicle. Because there are flashing signal lights on the roof of emergency vehicles, which most other vehicles do not have. In addition, there are words such as "First Aid 120" around the body of the emergency vehicle. In addition, there is a red cross mark on the front part of the emergency vehicle. Therefore, the present invention performs local feature extraction on the detected vehicle based on this information, and performs feature matching, thereby realizing the detection and recognition of emergency vehicles.
[0046] First of all, offline learning of vehicle characteristics and local characteristics of emergency vehicles (including roof lights, body emerge...

The invention belongs to the field of driving, and particularly relates to a first-aid vehicle detection and avoidance method and a first-aid vehicle detection and avoidance system based on vehicle roof signal lamp detection. According to the invention, a visual sensor is used for carrying out vehicle detection. When a vehicle is detected, the signal lamp detection on the vehicle roof area and / orthe 120-mark detection on the vehicle body area and / or the red cross mark detection on the vehicle body area are / is carried out. The above detection result is subjected to weighted judgment, and thenwhether the vehicle is a first-aid vehicle or not is judged. If the vehicle is judged to be a first-aid vehicle, a prompt is triggered. According to the invention, according to three characteristics of a vehicle body, namely a corresponding roof signal lamp, a first-aid 120 mark on the vehicle body area, and a red cross mark or a blue cross mark on the vehicle body area, whether the vehicle is a first-aid vehicle or not is judged. That means, the accuracy of vehicle detection and recognition is increased, and the detection efficiency is improved.
Description
Technical field [0001] The invention belongs to the field of active driving, in particular to an emergency vehicle detection and avoidance method and system based on vehicle roof signal lamp detection. Background technique [0002] In recent years, with the rapid development of assisted driving and active driving, vehicle recognition and detection based on vehicle vision has been favored by many researchers. People remind the driver to keep a safe distance from the vehicle by detecting and ranging the vehicle within the detection range of the on-board visual sensor while the vehicle is traveling. This not only reduces the driver's driving burden, but also greatly improves driving safety. However, at present, various active driving and assisted driving products do not recognize specific vehicle types. Summary of the invention [0003] In view of the above-mentioned shortcomings in the prior art, the technical problem to be solved by the present invention is to provide an emergenc...
