Abstract
The present invention relates to a technology for collecting map information including terrain information through a collectible open map service without actual road measurement information and generating a simulation image by processing an image reflecting a type, a terrain condition, and the like of a road.
Claims19
A simulation image generation method used in evaluating and tuning an adaptive driving beam (ADB) system of a test vehicle, the method comprising:
- a map input step of receiving externally provided map information of a predetermined region, the map information providing road terrain information including road curvature and road height information along a length of road;
- prior to generating a simulation image, an information calculation step, performed by an arithmetic processor, of calculating simulation object information of a neighboring vehicle based on driving information of the test vehicle, driving information of a neighboring vehicle positioned around the test vehicle, and the map information, including the road curvature and road height information along a length of the road, wherein the simulation object information includes brightness and size information of lamps of the neighboring vehicle based on a distance between the test vehicle and the neighboring vehicle, positional information of the lamps of the neighboring vehicle based on an analysis of the road curvature from the test vehicle, and positional information of lamps of the neighboring vehicle based on an analysis of the road height from the test vehicle;
- an image generation step of generating the simulation image by reflecting the simulation object information of the neighboring vehicle in the map information;
- the simulation image for verifying and tuning performance of the ADB system based on response of the ADB system to the simulation image;
- and
- a tuning step of verifying and tuning performance of the ADB system based on response of the ABD system to the simulation image.
