A calibration device includes: a coordinate calculator that calculates coordinates of a plurality of rigid body-based points on a vehicle-based coordinate system from measurement values of respective distances between two points constituted by a combination of one of a plurality of vehicle-based points and one of the plurality of rigid body-based points, the plurality of vehicle-based points having known coordinates on the vehicle-based coordinate system and the plurality of rigid body-based points having known coordinates on a rigid body-based coordinate system; and a parameter calculator that calculates a relative attitude and a relative position of an origin as calibration parameters from a correspondence relationship between positions of image coordinates of the plurality of rigid body-based points within a captured image and the coordinates of the plurality of rigid body-based points on the vehicle-based coordinate system.

Calibration device and calibration method

A vehicular image processing system and a vehicular image processing apparatus are provided which combine an image from a photographing device for detection of an object forward of a vehicle and an image from a photographing device for parking assistance, thereby enabling detection, in a synthesized image, of an obstacle of which the entirety cannot be captured by each photographing device since the object is located in a region where detection is difficult in the conventional art, for example, the object is located at a short distance from the own-vehicle.
