Detailed Description

CUDA-accelerated point cloud processing.

Constructor & Destructor Documentation

~cudaPointCloud()

cudaPointCloud::~cudaPointCloud

(

)

Destructor.

cudaPointCloud()

cudaPointCloud::cudaPointCloud ( )

protected

Member Function Documentation

__attribute__()

struct cudaPointCloud::Vertex cudaPointCloud::__attribute__

(

(packed)

)

allocBufferGL()

bool cudaPointCloud::allocBufferGL ( )

protected

allocDepthResize()

bool cudaPointCloud::allocDepthResize ( size_t  size )

protected

Clear()

void cudaPointCloud::Clear

(

)

Clear the points, but keep the memory allocated.

Create()

static cudaPointCloud* cudaPointCloud::Create ( )

static

Create.

Extract() [1/2]

bool cudaPointCloud::Extract	(	float *	depth,
		float4 *	rgba,
		uint32_t	width,
		uint32_t	height
	)

Extract point cloud from depth map and optional RGBA image.

Extract() [2/2]

bool cudaPointCloud::Extract	(	float *	depth,
		uint32_t	depth_width,
		uint32_t	depth_height,
		float4 *	rgba,
		uint32_t	color_width,
		uint32_t	color_height
	)

Extract point cloud from depth map and optional RGBA image.

Free()

void cudaPointCloud::Free

(

)

Free the memory being used to store the point cloud.

GetData() [1/2]

Vertex* cudaPointCloud::GetData ( ) const

inline

Retrieve memory pointer to point cloud data.

GetData() [2/2]

Vertex* cudaPointCloud::GetData ( size_t  index ) const

inline

Retrieve memory pointer to a specific point.

GetMaxPoints()

uint32_t cudaPointCloud::GetMaxPoints ( ) const

inline

Retrieve the max number of points in memory.

GetMaxSize()

size_t cudaPointCloud::GetMaxSize ( ) const

inline

Retrieve the maximum size in bytes of the point cloud.

GetNumPoints()

uint32_t cudaPointCloud::GetNumPoints ( ) const

inline

Retrieve the number of points being used.

GetSize()

size_t cudaPointCloud::GetSize ( ) const

inline

Retrieve the size in bytes currently being used.

HasRGB()

bool cudaPointCloud::HasRGB ( ) const

inline

Does the point cloud have RGB data?

Render()

bool cudaPointCloud::Render

(

)

Render the point cloud with OpenGL.

Reserve()

bool cudaPointCloud::Reserve

(

uint32_t

maxPoints

)

Allocate and reserve memory for the max number of points.

Note

Memory is reserved automatically by Extract(), but if you know in advance the maximum number of points it is good practice to call Reserve() ahead of time.

Save()

bool cudaPointCloud::Save

(

const char *

filename

)

Save point cloud to PCD file.

SetCalibration() [1/3]

bool cudaPointCloud::SetCalibration

(

const char *

filename

)

Set the intrinsic camera calibration.

SetCalibration() [2/3]

void cudaPointCloud::SetCalibration

(

const float

K[3][3]

)

Set the intrinsic camera calibration.

SetCalibration() [3/3]

void cudaPointCloud::SetCalibration	(	const float2 &	focalLength,
		const float2 &	principalPoint
	)

Set the intrinsic camera calibration.
