Embodiment Construction

[0061] in figure 1 A scene on a street 101 is shown in, on which a vehicle 102 travels from bottom to top into an illuminated area, and the area is characterized by a lamp 105. At the beginning, the vehicle is driving with the standard light 103, and the system recognizes the light at the time of passing the point 110 from the interval 106 in front of the first light. Likewise, the second light is detected at the point 111 in front of the second light at the distance 106 and the urban light 104 is switched on at that position. After driving through the illuminated area, the system recognizes the last light temporarily at point 112, where the system does not yet know that it is the last light at the location. After no other lights are detected in the de-bounce interval 107, the area is no longer evaluated as "illuminated" in point 113. After the back time or the back path 108, the conversion from the urban light 104 to the standard light 103 is performed at point 114.

Abstract

Method and device for debounced light signature changes (105, 110, 111, 112) (e.g. street lamps, headlights of other vehicles) detected by a camera (31) for a vehicle (102) image data, wherein light signature changes are identified in a consecutive sequence of images, and the time interval between light signature changes is determined, wherein the speed of the vehicle (37) is determined by the time interval between light signature changes The spatial spacing between light signature changes, where the debounce is based on the spatial spacing.

Description

Technical field [0001] The present invention relates to a method and device for debounce light characteristic changes (for example, street lights, headlights of other vehicles), the light characteristic changes are determined by the image data of the vehicle's camera, wherein, in a continuous image sequence Identify the light characteristic changes and determine the time interval between the light characteristic changes, wherein the spatial interval between the light characteristic changes is determined according to the speed of the vehicle and the time interval between the light characteristic changes, wherein the debounce is based on Spatial spacing. Background technique [0002] Recently, systems for actively controlling vehicle lighting devices (headlights) have been provided on the market. The purpose of the measures described is first to provide the driver with the best visibility of the lane in front of him or related traffic conditions, and secondly (secondarily) to avoi...
