Distance measurement apparatus for vehicle |
摘要 |
The distance to a target object is measured by capturing the image in front of the driving vehicle using an image sensor, identifying a target object such as a vehicle ahead to which the distance is to be measured, and projecting a laser beam onto the target object. The distance to the target object is measured by angular surveying, using an image sensor for capturing an image as a laser light detection unit.
