Detailed Description
template<typename PointT>
class pcl::TfQuadraticXYZComparison< PointT >
A comparison whether the (x,y,z) components of a given point satisfy (p'Ap + 2v'p + c [OP] 0).
Here [OP] stands for the defined pcl::ComparisonOps, i.e. for GT, GE, LT, LE or EQ; p = (x,y,z) is a point of the point cloud; A is 3x3 matrix; v is the 3x1 vector; c is a scalar.
One can also use TfQuadraticXYZComparison for simpler geometric shapes by defining the quadratic parts (i.e. the matrix A) to be zero. By combining different instances of TfQuadraticXYZComparison one can get more complex shapes. For example, to have a simple cylinder (along the x-axis) of specific length one needs three comparisons combined as AND condition:
- The cylinder: A = [0 0 0, 0 1 0, 0 0 1]; v = [0, 0, 0]; c = radius²; OP = LT (meaning "<")
- X-min limit: A = 0; v = [1, 0, 0]; c = x_min; OP = GT
- X-max ...

transformComparison() [1/2]
|
inline |
transform the coordinate system of the comparison.
If you think of the transformation to be a translation and rotation of the comparison in the same coordinate system, you have to provide the inverse transformation. This function does not change the original definition of the comparison. Thus, each call of this function will assume the original definition of the comparison as starting point for the transformation.
- Parameters
-
transform the transformation (rotation and translation) as an affine matrix.
