Huawei's new patent on autopilot can reverse predict traffic lights or traffic police gestures through intersection information.

CTOnews.com, December 1 (Xinhua) some time ago, Huawei showed off the "muscles" of unmanned valet parking through the Wisdom S7. Cars can find their own parking spaces in shopping malls and can read the command gestures of security guards. The latest patent shows that Huawei also has a layout in predicting traffic police gestures.

Recently, Huawei Technology Co., Ltd. applied for a patent for "traffic signal status detection method, device and storage medium", according to Aiqi check.

CTOnews.com learned from the patent abstract that the patent relates to the field of self-driving technology, which inversely predicts the state of related traffic signals (traffic lights or traffic police gestures) through the traffic behavior information of the target intersection, which can avoid relying only on traffic signal image perception to realize traffic signal state detection in related technology, and improve the accuracy of traffic signal state detection.

The method of the invention includes: obtaining the traffic behavior information of the target intersection, the target intersection is the intersection where the traffic signal light of the vehicle driving direction is located, and the traffic behavior information indicates the behavior of at least one traffic participant; according to the traffic behavior information, determine the state detection result of the traffic signal, the traffic signal includes the traffic signal light or the traffic police gesture signal, and the state detection result indicates the state of the traffic signal.
