Abstract

The invention discloses a traffic sign recognition method and device. The method comprises the following steps: acquiring image data from a camera; Detecting a region of interest of a current frame ofthe image data by using a deep learning technology to obtain an initial traffic sign detection result; Tracking the traffic sign detection result to obtain a final traffic sign detection result whichcan be a tracking result; And predicting the region of interest of the next frame according to the tracking result.

Description

technical field [0001] Generally speaking, the present invention relates to the field of image processing and automobile safety assisted driving, and specifically, the present invention relates to a traffic sign (especially a traffic light) recognition method and device. Background technique [0002] With the development of technology, autonomous driving technology of robot-driven vehicles (for example, "UAV" or "drone") has gradually become a hot topic. In the field of autonomous driving, traffic signal detection technology is one of the key technologies for robot-driven vehicles. Failure to properly detect and classify traffic lights could result in a violation of traffic regulations and could result in a serious traffic accident resulting in death, injury, and / or significant damage. [0003] Traditional traffic signal detection schemes are mainly based on traditional features, mainly using color histogram and HOG (Histogram of Oriented Gradient) features to describe the ...
