1. A driver assistance apparatus comprising:
- a stereo camera to acquire stereo images; and
a processor in communication with the stereo camera, the processor configured to perform calibration based on first regions of the stereo images, the first regions comprising one of vehicle structure objects or objects of structures external to a vehicle in a calibration mode and to detect a distance to an object ahead of the vehicle based on second regions not comprising one of the vehicle structure objects or the objects of structures external to a vehicle in a normal operational mode.

Abstract
A driver assistance apparatus and a vehicle including the same are disclosed. The driver assistance apparatus includes a stereo camera and a processor to perform a calibration based on first regions that include objects for vehicle structures or external to the vehicle in stereo images acquired by the stereo camera in a calibration mode and to detect a distance to an object ahead of the vehicle based on second regions not including the objects for the vehicle structures in the stereo images acquired by the stereo camera in a normal mode. Consequently, it is possible to accurately perform distance detection based on images photographed by the stereo camera.

12. A vehicle comprising:
-
a steering drive unit to drive a steering apparatus; a brake drive unit to drive a brake apparatus; a power source drive unit to drive a power source; a suspension drive unit to drive a suspension apparatus; a stereo camera to acquire stereo images; and a processor in communication with the stereo camera, the processor configured to perform calibration based on first regions of the stereo images, the first regions comprising one of vehicle structure objects or objects of structures external to a vehicle in a calibration mode and to detect a distance to an object ahead of the vehicle based on second regions not comprising one of the vehicle structure objects or the objects of structures external to a vehicle in a normal operational mode; and a controller to generate a control signal to control at least one of the steering drive unit, the brake drive unit, the power source drive unit, and the suspension drive unit based on the detected distance to the object ahead of the vehicle. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
