<p><P>PROBLEM TO BE SOLVED: To detect a vehicle traveling in the periphery of a self vehicle and efficiently calculate a collision time till the detected vehicle collides with the self vehicle. <P>SOLUTION: When a vehicle pattern is detected from a set of images (Yes in Step S204), a vehicle detection device calculates a collision time till the vehicle collides with a self vehicle on the basis of a partial image as the vehicle pattern. On the other hand, when no vehicle pattern is detected from the set of images (No in Step S204), the vehicle detection device calculates optical flows provided by respective feature points of the set of images. The collision time till the vehicle collides with the self vehicle is calculated based on the optical flows. The collision time can be thus highly efficiently calculated in a short time according to the peripheral environment. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
