Detailed Description

This module approximates the depicted geometry of a depth image.

Author: Jonas Lukasczyk jl@jl.nosp@m.uk.d.nosp@m.e

Date: 1.7.2018

This module approximates the depicted geometry of a depth image solely based on the depth values and the corresponding camera parameter.

Member Function Documentation

◆ execute()

template<class dataType, class idType>

int ttk::DepthImageBasedGeometryApproximation::execute	(	float *	pointCoordinates,
		double *	triangleDistortions,
		idType *	connectivityList,
		idType *	offsetArray,
		const dataType *	depthValues,
		const double *	camPos,
		const double *	camDir,
		const double *	camUp,
		const double *	camNearFar,
		const double *	camHeight,
		const double *	resolution ) const

This function computes for an input depth image and its corresponding camera parameters the original 3D position of each pixel and then connects neighbouring pixels via triangles. The function also returns a scalar array (triangleDistortions) that records the distortion of each triangle that can later be used to filter the resulting geometry.
