virtual void cv::rgbd::Odometry::checkParams ( ) const

protectedpure virtual

Implemented in cv::rgbd::FastICPOdometry, cv::rgbd::RgbdICPOdometry, cv::rgbd::ICPOdometry, and cv::rgbd::RgbdOdometry.

bool cv::rgbd::Odometry::compute	(	const Mat &	srcImage,
		const Mat &	srcDepth,
		const Mat &	srcMask,
		const Mat &	dstImage,
		const Mat &	dstDepth,
		const Mat &	dstMask,
		OutputArray	Rt,
		const Mat &	initRt = `Mat()`
	)		const

Method to compute a transformation from the source frame to the destination one. Some odometry algorithms do not used some data of frames (eg. ICP does not use images). In such case corresponding arguments can be set as empty Mat. The method returns true if all internal computions were possible (e.g. there were enough correspondences, system of equations has a solution, etc) and resulting transformation satisfies some test if it's provided by the Odometry inheritor implementation (e.g. thresholds for maximum translation and rotation).

Parameters

srcImage	Image data of the source frame (CV_8UC1)
srcDepth	Depth data of the source frame (CV_32FC1, in meters)
srcMask	Mask that sets which pixels have to be used from the source frame (CV_8UC1)
dstImage	Image data of the destination frame (CV_8UC1)
dstDepth	Depth data of the destination frame (CV_32FC1, in meters)
dstMask	Mask that sets which pixels have to be used from the destination frame (CV_8UC1)
Rt	Resulting transformation from the source frame to the destination one (rigid body motion): dst_p = Rt * src_p, where dst_p is a homogeneous point in the destination frame and src_p is homogeneous point in the source frame, Rt is 4x4 matrix of CV_64FC1 type.
initRt	Initial transformation from the source frame to the destination one (optional)

bool cv::rgbd::Odometry::compute	(	Ptr< OdometryFrame > &	srcFrame,
		Ptr< OdometryFrame > &	dstFrame,
		OutputArray	Rt,
		const Mat &	initRt = `Mat()`
	)		const

One more method to compute a transformation from the source frame to the destination one. It is designed to save on computing the frame data (image pyramids, normals, etc.).

		int	cacheType
	)		const

virtual

Python:
	retval	=	cv.rgbd_Odometry.prepareFrameCache(	frame, cacheType	)

Prepare a cache for the frame. The function checks the precomputed/passed data (throws the error if this data does not satisfy) and computes all remaining cache data needed for the frame. Returned size is a resolution of the prepared frame.
