Apparatus for compensating camera image and operating method thereof
First Claim
1. A camera image compensating apparatus for a vehicle, comprising:
- a detecting unit which detects a base line and a vehicle body contour line by analyzing an image signal which is created by a camera which uses a predetermined camera parameter;
a coordinate storing unit which stores a first reference image coordinate value and a second reference image coordinate value;
a first coordinate calculating unit which calculates a first base line image coordinate value with respect to the base line and calculates a first vehicle body contour line image coordinate value with respect to the vehicle body contour line;
a coordinate comparing unit which compares the first reference image coordinate value and the first base line image coordinate value to calculate a first comparison result and compares the second reference image coordinate value and the first vehicle body contour line image coordinate value to calculate a second comparison result;
a correcting unit which calculates angle change information of the camera based on the first and second comparison results, calculates correction information based on the angle change information, and corrects the camera parameter using the correction information; and
a second coordinate calculating unit which calculates a second base line image coordinate value with respect to the base line and calculates a second vehicle body contour line image coordinate value with respect to the vehicle body contour line by applying the corrected camera parameter to the image signal created by the camera.
