Description:
3D Space Coordinate Transformations
This folder contains 3 files (m-functions) :
- t2x.m Transformation Matrix to Generalized Position Vector.
- x2t.m Generalized Position Vector to Transformation Matrix.
- m2m.m Mass/Inertia Tensor transformation with coordinate change.
In the Generalized Position Vector the orientation can be expressed with:
- unit quaternion,
- Euler angles xyz (roll, pitch, and yaw),
- Euler angles zyz (rotation, precession, and mutation),
- unit vector and rotation angle,
- Denavitt-Hartemberg parameters.
Conversion between the above orientation systems can be easily achieved.
The three files work independently on each other, but since they work
on the same objects it is somewhat useful to keep them in the same folder. -

Description: 刚性位置变化计算，输入物体在空间坐标系中的坐标，以及旋转向量和平移向量，计算其在摄像机坐标系中的坐标。- [Y,dYdom,dYdT] = rigid_motion(X,om,T)
Computes the rigid motion transformation Y = R*X+T, where R = rodrigues(om).
INPUT: X: 3D structure in the world coordinate frame (3xN matrix for N points)
(om,T): Rigid motion parameters between world coordinate frame and camera reference frame
om: rotation vector (3x1 vector) T: translation vector (3x1 vector)
OUTPUT: Y: 3D coordinates of the structure points in the camera reference frame (3xN matrix for N points)
dYdom: Derivative of Y with respect to om ((3N)x3 matrix)
dYdT: Derivative of Y with respect to T ((3N)x3 matrix)
Definitions:
Let P be a point in 3D of coordinates X in the world reference frame (stored in the matrix X)
The coordinate vector of P in the camera reference frame is: Y = R*X+ T
where R is the rotation matrix corresponding to the rotation vector om: R = rodrigues(om)

Description: 图像处理 并行处理 matlab Since images can be represented by 2D or 3D matrices and the MATLAB processing engine
relies on matrix representation of all entities, MATLAB is particularly suitable for implemen‐
tation and testing of image processing workflows. The Image Processing Toolbox
™
(IPT)
includes all the necessary tools for general-purpose image processing incorporating more than
300 functions which have been optimised to offer good accuracy and high speed of processing.
Moreover, the built-in Parallel Computing Toolbox
™
(PCT) has recently been expanded and
now supports graphics processing unit (GPU) acceleration for some functions of the IPT.
However, for many image processing applications we still need to write our own code, either
in MATLAB or, in the case of GPU-accelerated applications requiring specific control over
GPU resources, in CUDA (Nvidia Corporation, Santa Clara, CA, USA).-the first part is dedicated to some essential tools of the IPT that can be used in
image analysis and assessment as well as in extraction of useful information for further
processing and assessment. These include retrieving information about digital images, image
adjustment and processing as well as feature extraction and video handling. The second part
is dedicated to GPU acceleration of image processing techniques either by using the built-in
PCT functions or through writing our own functions. Each section is accompanied by MAT‐
LAB example code. Platform: |
