Problems solved by technology

[0004] Whether an unmanned vehicle can correctly identify traffic lights during driving has a great impact on driving safety, so a complete set of test methods and devices are needed to test whether the traffic light recognition system of unmanned vehicles can accurately identify traffic lights at intersections, as mentioned above It can be seen that unmanned vehicles need to use telephoto cameras, positioning systems based on GPS (Global Positioning System, Global Positioning System) / IMU (Inertial measurement unit, inertial measurement unit) and radar equipment and high-precision map data when performing traffic light recognition. , faced with the problems of complex test environment deployment, high test cost and long test cycle during the test process

Abstract

The invention discloses a method and a device for determining recognition performance of a traffic lamp recognition system. The method comprises the steps of: receiving acquired video information containing a traffic lamp, and determining truth-value data of the video information; generating a simulated positioning system according to vehicle state information, and generating a simulated high-precision map according to facility information of the traffic lamp; acquiring recognition content of the traffic lamp recognition system according to the video information, the simulated positioning system and the simulated high-precision map; and determining recognition performance of the traffic lamp recognition system according to the truth-value data and the recognition content. The method and the device achieve the fast, accurate and efficient evaluation of the traffic lamp recognition system, and greatly reduce the test cost.

Description

technical field [0001] Embodiments of the present invention relate to computer technology, and in particular to a method and device for evaluating a traffic light recognition system. Background technique [0002] With the development of artificial intelligence, smart cars have gradually entered the public's field of vision. Smart cars are also called unmanned vehicles, which sense the surrounding environment of the vehicle through on-board sensors, and the central control system of the vehicle comprehensively controls the steering and speed of the vehicle based on information such as roads and obstacles perceived by the sensors, so that the vehicle can be safely and reliably on the road. drive. [0003] Unmanned vehicles need to effectively identify traffic lights while driving on the road. The specific identification process is: use a telephoto camera to collect video images of traffic lights, determine the current position and attitude of the vehicle (orientation, rotatio...
