Signature¶

def sdynpy.fileio.sdynpy_vic.camera_matrix_from_vic_parameters(intrinsics, extrinsics=None)

Computes K and RT Camera matrices from information in the project.xml file

This function takes VIC3D Camera Calibration information and makes a camera intrinsic and extrinsic matrix. This can be extracted from the project.xml file inside the unzipped Z3D project file.

Parameters¶

• intrinsics : iterable A list of parameters that define the camera intrinsic properties. They are ordered cx, cy, fx, fy, s

• extrinsics : iterable A list of parameters that define the camera extrinsic properties. They are ordered rx, ry, rz, tx, ty, tz

Returns¶

• K : ndarray A 3 x 3 upper triangular array consisting of the camera intrinisc parameters.

• RT : ndarray A 3 x 4 array where the first three columns are an orthogonal matrix denoting a rotation matrix, and the last column is a translation.
