碩士 === 國立交通大學 === 網路工程研究所 === 105 === The purpose of this thesis is to apply the method that can automatically correct the car camera by using reference image. The method includes : extract image by correcting reference image . Identify multiple first and second characteristic image in reference image, and get the coordinates that is first perspective and secondperspective, and analysis the relationship between them . According to the relationship , transform the input image to output image. In today , have a lot of technology to support car security , in general , these car secure support system (multi view camera system , front crash alarm system , back secure support system , side blind alarm system …) should have a car camera , use the camera to get the car outside image, before the car sale , the camera installed in car should be correct first . At present , traditional man-machine car camera correct method should depends on manual adjustment , ensure the image characteristic image can fit the default condition by using the man-machine operate to adjust to the right position. And the system compute the camera extrinsic parameters and intrinsic parameters to transform the coordinates. This thesis apply the method that automatically correct car camera by using reference image.
