Axis-Angle Rotation(Rodrigues Rotation) It is used as a 3d rotation method that can improve the disadvantages of Euler Angle. 3D rotation is more flexible than Euler Angle. : the axis of rotation, orange line- : a point to rotate- 𝜃 : an angle to rotate- : the final point of rotation- : a point of the world space- : the center of a rotating plane" data-ke-type="html">HTML 삽입미리보기할 수 없는 소스 - ..

Image Homographies Adjust the angle.Here are several consecutive images taken. Attach these images in order.Images are put together alternately. This is because the angle of the picture is different. Use Homography to adjust the angle. It requires 3 conditions. 1. The subject should be plane. 2. If it's not a plane, at least it should be close to a plane.Because even if it's not actually a plane..

The tree(3D) ←→ Camera(2D) The tree : The point we're seeing with our eyes, 3D point which has world coordinateCamera : When we take the tree, it transforms to 2DWhen we take the picture of the tree, the camera influenced by the Camera intrinsic parameters-lens, the distance between the lens and the image sensor, the angle between the lens and the image sensor, etc. Therefore, when finding the p..

Transformation matrix Rotation and parallel translation only in 3D Transformations(not like a 2D Transformations).A matrix that rotates points (X, Y, Z) in a 3D space by θ radians based on the X, Y, and Z axes. HTML 삽입미리보기할 수 없는 소스 HTML 삽입미리보기할 수 없는 소스- 3D Transformation matrix(Rigid Transformation)  HTML 삽입미리보기할 수 없는 소스- Convert to homogeneous coordinate system HTML 삽입미리보기할 수 없는 소스 https://dark..

2D Transformations A method used to model the matching relationship between two images directly on a 2D plane.Rigid Transformation(Euclidean transformation) Only change its position and orientation while maintaining its shape and size.In other words, it is a transformation that only allows rotation and translation.Translation  HTML 삽입미리보기할 수 없는 소스- Degree of Freedom(DOF) : t1, t2Shearing If you ..
