Abstract
An image pick-up means mounted in the motor vehicle picks up a side direction of a driver's own vehicle. An approaching object detecting means detects an approaching degree of an approaching object which approaches his own vehicle from a side direction road crossing his own vehicle on the basis of two images picked up at two timings apart by a prescribed interval by the image pick-up means. A danger decision means decides a danger on the basis of the approaching degree. In such a configuration, a side-monitoring apparatus for a motor vehicle can accurately know the danger of collision with the object approaching from the side direction road.
Claims9
A side-monitoring apparatus for a motor vehicle comprising:
- image pick-up means mounted in the motor vehicle for picking up an image in a side direction of the vehicle;
- approaching object detecting means for detecting approaching degree of an approaching object which approaches a driver's own vehicle from a side direction road crossing the driver's own vehicle on the basis of two image picked up at two timings apart by a prescribed interval by said image pick-up means, wherein an optical flow for each object in the two images is determined and optical flows having a backward direction are eliminated;
- and
- danger decision means for deciding a danger on the basis of said approaching degree and the location and magnitude of the optical flows, wherein said approaching degree is changed based upon movement of the object in the two images in the two timings and movement of the driver'own vehicle.
