void cv::rgbd::depthTo3d	(	InputArray	depth,
		InputArray	K,
		OutputArray	points3d,
		InputArray	mask = `noArray()`
	)

Converts a depth image to an organized set of 3d points. The coordinate system is x pointing left, y down and z away from the camera

Parameters

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	the resulting 3d points. They are of depth the same as `depth` if it is CV_32F or CV_64F, and the depth of `K` if `depth` is of depth CV_U
mask	the mask of the points to consider (can be empty)

void cv::rgbd::depthTo3dSparse	(	InputArray	depth,
		InputArray	in_K,

bool cv::rgbd::isValidDepth ( const float & depth )

inline

Checks if the value is a valid depth. For CV_16U or CV_16S, the convention is to be invalid if it is a limit. For a float/double, we just check if it is a NaN

Parameters

depth the depth to check for validity

bool cv::rgbd::isValidDepth ( const double & depth )

inline

bool cv::rgbd::isValidDepth ( const short int & depth )

inline

bool cv::rgbd::isValidDepth ( const unsigned short int & depth )

bool cv::rgbd::isValidDepth ( const unsigned int & depth )

void cv::rgbd::registerDepth	(	InputArray	unregisteredCameraMatrix,
		InputArray	registeredCameraMatrix,
		InputArray	registeredDistCoeffs,
		InputArray	Rt,
		InputArray	unregisteredDepth,
		const Size &	outputImagePlaneSize,
		OutputArray	registeredDepth,
		bool	depthDilation = `false`
	)

Registers depth data to an external camera Registration is performed by creating a depth cloud, transforming the cloud by the rigid body transformation between the cameras, and then projecting the transformed points into the RGB camera.

uv_rgb = K_rgb * [R | t] * z * inv(K_ir) * uv_ir

Currently does not check for negative depth values.

Parameters

unregisteredCameraMatrix	the camera matrix of the depth camera
registeredCameraMatrix	the camera matrix of the external camera
registeredDistCoeffs	the distortion coefficients of the external camera
Rt	the rigid body transform between the cameras. Transforms points from depth camera frame to external camera frame.
unregisteredDepth	the input depth data
outputImagePlaneSize	the image plane dimensions of the external camera (width, height)
registeredDepth	the result of transforming the depth into the external camera
depthDilation	whether or not the depth is dilated to avoid holes and occlusion errors (optional)

void cv::rgbd::rescaleDepth	(	InputArray	in,
		int	depth,
		OutputArray	out
	)

If the input image is of type CV_16UC1 (like the Kinect one), the image is converted to floats, divided by 1000 to get a depth in meters, and the values 0 are converted to std::numeric_limits<float>::quiet_NaN() Otherwise, the image is simply converted to floats

Parameters

in	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), it is assumed in meters)
depth	the desired output depth (floats or double)
out	The rescaled float depth image

void cv::rgbd::warpFrame	(	const Mat &	image,
		const Mat &	depth,
		const Mat &	mask,
		const Mat &	Rt,
		const Mat &	cameraMatrix,
		const Mat &	distCoeff,
		OutputArray	warpedImage,
		OutputArray	warpedDepth = `noArray()`,
		OutputArray	warpedMask = `noArray()`
	)

Warp the image: compute 3d points from the depth, transform them using given transformation, then project color point cloud to an image plane. This function can be used to visualize results of the Odometry algorithm.

Parameters

image	The image (of CV_8UC1 or CV_8UC3 type)
depth	The depth (of type used in depthTo3d fuction)
mask	The mask of used pixels (of CV_8UC1), it can be empty
Rt	The transformation that will be applied to the 3d points computed from the depth
cameraMatrix	Camera matrix
distCoeff	Distortion coefficients
warpedImage	The warped image.
warpedDepth	The warped depth.
warpedMask	The warped mask.
