Abstract
A monitor system of a vehicle includes an image-measured distance detector for detecting a distance data between a vehicle and a three-dimensional object based on information of an image in front of the vehicle, a laser-measured distance detector for detecting the distance data between the vehicle and the object by projecting a laser beam from the vehicle, and a three-dimensional object recognition device for recognizing the object based on the distance data detected by the image-measured distance detector and the distance data detected by the laser-measured distance detector. The three-dimensional object recognition device recognizes the object by coordinating the distance data and by making the distance data of a horizontal direction ineffective, when the two sets of distance data have a width within a present value and the difference between the distance values of the two sets of distance data is within a preset distance value.
