ptcloudfunctionOpenCV 5.0.0
import { depthTo3d } from '@banou/opencv-wasm'

Use after await initOpenCV(). See the initialization and named imports guide.

ARGUMENTSdepth, K, points3d, mask
FUNCTIONdepthTo3d
RETURN TYPEvoid
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Converts a depth image to 3d points. If the mask is empty then the resulting array has the same dimensions as depth, otherwise it is 1d vector containing mask-enabled values only. The coordinate system is x pointing left, y down and z away from the camera

depthTo3d(depth: Mat, K: Mat, points3d: Mat, mask: Mat): void;
2 available overloads
depthTo3d(depth: Mat, K: Mat, points3d: Mat): void;
depthTo3d(depth: Mat, K: Mat, points3d: Mat, mask: Mat): void;
depth

the depth image (if given as short int CV_U, it is assumed to be the depth in millimeters (as done with the Microsoft Kinect), otherwise, if given as CV_32F or CV_64F, it is assumed in meters)

K

The calibration matrix

points3d

Output destination, filled by the native operation. the resulting 3d points (point is represented by 4 channels value [x, y, z, 0]). They are of the same depth as depth if it is CV_32F or CV_64F, and the depth of K if depth is of depth CV_16U or CV_16S

mask

the mask of the points to consider (can be empty)
