The present invention relates to a speed bump sensor using stereo vision, comprising: a vision module including a position sensing module installed on a vehicle and providing information of a road on which the vehicle drives, a first camera shooting an object on the road and obtaining a first image information, a second camera shooting the object on the road at a different angle with the first camera and obtaining a second image information, and a distance measurement unit measuring the distance (r) with the object based on the first image information and the second image information; a controller deciding types of the road from the road information, and deciding whether a speed bump is existed in the first image information and the second image information if the road is a backside road; and a power/braking module reducing the speed of the vehicle based on the distance (r) with the object measured in the distance measurement unit if the road is the backside road, and the speed bump is existed on the road, wherein the distance (r) with the object measured in the distance measurement unit is calculated by math formula 1. |
