§ compute() [1/2]

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
Python:
retval, Rt=cv.rgbd_Odometry.compute(srcImage, srcDepth, srcMask, dstImage, dstDepth, dstMask[, Rt[, initRt]])
retval, Rt=cv.rgbd_Odometry.compute2(srcFrame, dstFrame[, Rt[, initRt]])

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
srcImageImage data of the source frame (CV_8UC1)
srcDepthDepth data of the source frame (CV_32FC1, in meters)
srcMaskMask that sets which pixels have to be used from the source frame (CV_8UC1)
dstImageImage data of the destination frame (CV_8UC1)
dstDepthDepth data of the destination frame (CV_32FC1, in meters)
dstMaskMask that sets which pixels have to be used from the destination frame (CV_8UC1)
RtResulting 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.
initRtInitial transformation from the source frame to the destination one (optional)

§ compute() [2/2]

bool cv::rgbd::Odometry::compute ( Ptr< OdometryFrame > &  srcFrame,
Ptr< OdometryFrame > &  dstFrame,
OutputArray  Rt,
const Mat initRt = Mat() 
) const
Python:
retval, Rt=cv.rgbd_Odometry.compute(srcImage, srcDepth, srcMask, dstImage, dstDepth, dstMask[, Rt[, initRt]])
retval, Rt=cv.rgbd_Odometry.compute2(srcFrame, dstFrame[, Rt[, initRt]])

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.

Parameters
frameThe odometry which will process the frame.
cacheTypeThe cache type: CACHE_SRC, CACHE_DST or CACHE_ALL.

Reimplemented in cv::rgbd::RgbdICPOdometry, cv::rgbd::ICPOdometry, and cv::rgbd::RgbdOdometry.
