Abstract
A traveling environment recognition apparatus includes a camera, a first traveling environment recognition unit, a second traveling environment recognition unit, and an imaging mode switching unit. The first traveling environment recognition unit calculates the movement amount of a vehicle on the basis of an optical flow in an image captured by the camera. The second traveling environment recognition unit calculates a vehicle position in the real space on the basis of positioning signals received from positioning satellites. The imaging mode switching unit drives the camera in a first imaging mode when positioning accuracy based on the positioning signals is high, while the imaging mode switching unit drives in a second imaging mode when the positioning accuracy is low. When the camera is driven in the second imaging mode, the second traveling environment recognition unit estimates the vehicle position on a road map based on the movement amount.
