DETERMINATION OF LOCATION COORDINATES OF LIGHT SOURCES IN ENVIRONMENTAL SCHOOLS

摘要

The invention relates to a device and a method for estimating position coordinates and the type of light sources in ambient images, in particular in ambient images of a surround-view camera in vehicles. The type of light source (120, 125, 128) can be a spot light source or a direction light source. The method comprises the steps: a) capturing a surrounding environment (100) in the form of an image (300) of the surrounding environment by means of a camera (200); b) determining areas of increased brightness (310) of the image (300) of the surrounding environment, specifically of an amount of pixels, the brightness of which exceeds a predefined threshold; c) determining position coordinates (335) of the light source (120, 125, 128) from the areas of increased brightness (310) and according to a first calculation method; d) determining the type of light source (120, 125, 128) from the shadow (350) of an object (150), in particular a vehicle, on the image (300) of the surrounding environment.
