Length decisive manner of visibility for car Tanks driver

摘要

The method involves determining luminosity of pixels of a region of an image taken in a field of view of a driver to result in a luminosity curve (LUX), where the image is defined by an assembly of pixels and scanning lines (BL). A tangent (AA`) is determined to the curve at a location representing a region of luminosity independent of a disturbance element. Another tangent (CC`) is determined to the curve at a location representing stabilization of the luminosity. A sweeping line (FBL) is determined according to the tangents, where the line represents a visibility distance. Independent claims are also included for the following: (1) a device for determining a visibility distance for a driver of vehicle (2) a computer program product comprising instructions for implementing a method for determining visibility distance for a driver of vehicle.
