Driving route status recognition based on digital image technique

In order to monitor driver working states and vehicle traveling conditions at real time, the recognition property of driving routes relative to road traffic mark was analyzed by using the images taken from on-board CCD image sensor, the models of perspective projection and vehicle traveling routes recognition were established by image understanding and computer vision techniques, the vehicle's real three-dimensional positions relative to road traffic mark from the dots of planar images were computed.Computation result shows that vehicle's calculation traveling routes are coincident with reality, so that driver's some peccancy behaviors, such as driving along solid central-line, driving across solid central line and driving along converse roadway, can be decided correctly.
