Embodiment Construction
[0030] The following are specific embodiments of the present invention, and further describe the technical solution of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.
[0031] Such as Figure 1-4 As shown, a pedestrian recognition assistance system for a vehicle includes a camera 3 for shooting an external image of a target vehicle,
[0032] At least one mobile phone signal detector 2 is used to detect the presence of mobile phones in the effective area by transmitting the fundamental wave and receiving feedback signals; the mobile phone signal detector 2 includes at least one transmitter f for transmitting the set fundamental wave and at least one Receiver j for receiving the harmonics re-radiated by the corresponding fundamental wave through the metal node or / and PN node of the mobile phone. The mobile phone signal detector 2 detects the metal nodes and PN junctions in the mobile phone. So ...

The invention provides a pedestrian identification auxiliary system and a method of a vehicle, belonging to the technical field of automobile object identification. The system and the method address how to improve the accuracy of pedestrian identification. The system includes a camera for photographing an external image of a target vehicle, at least one mobile phone signal detector and a controller. The mobile phone signal detector and the camera are connected to the controller. The method comprises the following steps of: photographing an external image of a target vehicle; detecting the existence of a mobile phone object in an effective area by transmitting a fundamental wave and receiving a feedback signal; identifying the image data of the camera and calculating according to the data sent by the mobile phone signal detector; calculating the distance and the orientation of the mobile phone-carrying object sensed by the correspond target vehicle, and superposing the mobile phone-carrying object determined by the mobile phone signal detector and an image captured by the camera, so as to establish the specific position of the mobile phone-carrying object in the image so as to carryout pedestrian identification. The accuracy of pedestrian or cyclist identification is improved.
Description
technical field [0001] The invention belongs to the technical field of vehicle object recognition, and relates to a vehicle pedestrian recognition auxiliary system and method. Background technique [0002] With the rapid development of automotive intelligent technology, automotive intelligent security has received more and more attention from the industry. When the sensor detects that there is a risk of collision, it will give an early warning and assist the driver to apply sufficient braking. If the driver does not take any braking measures, it can also automatically perform emergency braking to avoid collision or reduce the collision speed. The existing vehicle safety technology is mainly assisted by the pedestrian recognition technology of AEB. AEB's pedestrian recognition technology uses the front-mounted camera based on image recognition technology to recognize complex targets such as people and cyclists. However, for the identification of pedestrians and cyclists, AE...
