DYNAMIC METHOD AND DEVICE FOR MEASURING THE LUMINANCE AND BACK-REFLECTION OF ROAD MARKINGS AND SIGNS AND OBTAINING THE SHAPE, POSITION AND DIMENSIONS THEREOF |
摘要 |
A dynamic measurement procedure of the luminance and retroreflection of the road markings and signals and obtention of the dimensions of the same from a vehicle that circulates on the road; illuminating the zone of interest; knowing the position of the vehicle; measuring the luminance by means of a light sensor in a single pass, at known distances or intervals; identifying and extracting one or several road markings and signals simultaneously in each measurement of luminance by means of algorithms; referencing the luminance both geometrically and in time, as well as the obtention of the shape, position and dimensions of the same; and the device for carrying out said procedure, which includes a luminous source, a system of global positioning of the vehicle, a light sensor, a camera, a data processor and a data storage device. |
