Abstract

The capabilities of the vehicle tracking systems based on data acquisition from a single camera with a linear processing characteristic are limited by the range of light radiation acquired at a given moment. Taking into account the fact that different vehicles present on a single video frame can be either underexposed, and overexposed (especially in the case of a highly reflective surface in the sunlight), the possibilities of distinguishing between them are limited. The paper presents a method of vehicle tracking with simultaneous acquisition of video frames with different exposure parameters. Aside from changing a single camera exposure it is also possible to use a double-camera variant, especially for distant objects, for which the shift on both images acquired simultaneously is negligible. The proposed method uses a modified Track-Before-Detect technique with additional data fusion in order to obtain the High Definition Range images used for the tracking of vehicles represented on the images as the objects with varying brightness and size.
