CALIBRATION APPARATUS FOR VEHICLE MOUNTED CAMERA
First Claim
1. An apparatus for calibrating a camera while a vehicle is moving, comprising:
- a rearward monitoring camera mounted in a vehicle to acquire image information;
a memory that stores a camera calibration program for computationally determining and calibrating mounting parameters of the camera while the vehicle is moving, using the image information acquired by the camera;
a gear position detector to detect gear positions of the vehicle and generates position signals according to the gear positions; and
a control unit that receives the image information, and when the gear position detector detects a position signal for other than a reverse gear position, that reads out and executes the camera calibration program stored in the memory.

9. A calibration apparatus for a vehicle mounted camera comprising:
-
a first camera for forward monitoring mounted in a vehicle; a second camera for rearward monitoring mounted in the vehicle; a memory that stores a moving camera calibration program for computationally determining and calibrating mounting parameters of the first camera according to image information acquired by the first camera and for computationally determining and calibrating mounting parameters of the second camera according to image information acquired by the second camera; a gear position detecting unit that detects the gear position of the vehicle and generates a position signal according to the gear position; and a control unit that receives the image information acquired by the second camera as input and reads out the moving camera calibration program stored in the memory to calibrate the second camera when the gear position detecting unit detects a position signal for a forward moving gear position; and receives the image information acquired by the first camera as input and reads out the calibration program stored in the memory to calibrate the first camera when the gear position detecting unit detects a position signal for the reverse gear position. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
