camera.utils — CV Utility Functions¶
The camera.utils module provides convenience methods for
normalization and look vector math operations.
New in version 0.1.0.
- autocnet.camera.utils.crossform(a)[source]¶
Convert a three element vector into a 3 x 3 skew matrix as per Hartley and Zisserman pg. 581
- autocnet.camera.utils.normalize(a)[source]¶
Normalize a set of coordinates such that the origin is translated to the center and then scaled isotropically such that the average distance from the origin is $sqrt{2}$.
- Parameters
a (arraylike) – (n,2) array of x,y or (n,3) homogeneous coordinates
- Returns
normalizer – (3,3) transformation matrix
- Return type
ndarray
