◆ operator()() [1/2]

bool pcl::gpu::KinfuTracker::operator()	(	const DepthMap &	depth,
		const View &	colors )

Processes next frame (both depth and color integration).

Please call initColorIntegration before invpoking this.

◆ setCameraMovementThreshold()

void pcl::gpu::KinfuTracker::setCameraMovementThreshold ( float threshold = 0.001f )

Sets integration threshold.

TSDF volume is integrated iff a camera movement metric exceedes the threshold value. The metric represents the following: M = (rodrigues(Rotation).norm() + alpha*translation.norm())/2, where alpha = 1.f (hardcoded constant)

Parameters

[in] threshold a value to compare with the metric. Suitable values are ~0.001

Sets truncation threshold for depth image for ICP step only! This helps to filter measurements that are outside tsdf volume.

Pass zero to disable the truncation.

Parameters

[in] max_icp_distance Maximal distance, higher values are reset to zero (means no measurement).

◆ setIcpCorespFilteringParams()

◆ setInitalCameraPose()

void pcl::gpu::KinfuTracker::setInitalCameraPose ( const Eigen::Affine3f & pose )

Sets initial camera pose relative to volume coordinate space.

Parameters

[in] pose Initial camera pose

◆ volume() [1/2]
