Camera Calibration Using Vanishing Points in Three Dimensions
Summary:
The subject of this thesis is to describe and explore the calibration method of
a camera with only our element a photo which has been pulled from the specific
camera. Once the calibration of cameras and computers are fully configured, you
apply a transformation to our original image. The aim of the transformation is
used as a means to check in practice the correct calibration of the camera. The
first major step toward achieving our goal is to find three vanishing points,
one for each of the three dimensions. The vanishing points from lines that are
parallel in the real world, but in our photograph these lines if extrapolated
to infinity intersect. Then it will be a complete description of how using the
vanishing points will be able to fully calibrate our camera. This is very
important because knowing the parameters of the camera then you will easily be
able to apply on the photo us any transformation. Then describe the
mathematical model of transformation that will be applied. In this thesis, the
chosen transformation is an imprint of a building facade. Finally illustrated
step by step the methods in practice and presents the results for different
images.
