Function Documentation

◆ dwPointCloudRangeImageCreator_bindInput()

DW_API_PUBLIC dwStatus dwPointCloudRangeImageCreator_bindInput	(	const dwPointCloud *	pointCloud,
		dwPointCloudRangeImageCreatorHandle_t	obj
	)

Binds input point cloud to range image creator.

Parameters

[in]	pointCloud	Pointer to input buffer
[in]	obj	Handle to range image creator

Returns: DW_SUCCESS
DW_INVALID_HANDLE If neither of given handle is valid
DW_INVALID_ARGUMENT If point cloud input is nullptr

◆ dwPointCloudRangeImageCreator_bindOutput()

DW_API_PUBLIC dwStatus dwPointCloudRangeImageCreator_bindOutput	(	dwImageHandle_t	image,
		dwPointCloudRangeImageCreatorHandle_t	obj
	)

Binds output range image to range image creator.

Parameters

[in]	image	Handle to output range image
[in]	obj	Handle to range image creator

Returns: DW_SUCCESS
DW_INVALID_HANDLE If neither of given handle is valid
DW_INVALID_ARGUMENT If image is nullptr, image properties are not correct or memory type of input/output is inconsistent.

◆ dwPointCloudRangeImageCreator_bindOutputPointCloud()

DW_API_PUBLIC dwStatus dwPointCloudRangeImageCreator_bindOutputPointCloud	(	dwPointCloud *	pointCloud,
		dwPointCloudRangeImageCreatorHandle_t	obj
	)

Binds output point cloud to range image creator.

Parameters

[in]	pointCloud	Pointer to output point cloud. If null provided, any currently bound point cloud will be unbound
[in]	obj	Handle to range image creator

Returns: DW_SUCCESS
DW_INVALID_HANDLE If given handle is not valid
DW_INVALID_ARGUMENT If memory type or size of input/output is inconsistent.

Note: Output point cloud is optional. It may be used in couple with DW_POINT_CLOUD_IMAGE_TYPE_DISTANCE or DW_POINT_CLOUD_IMAGE_TYPE_INTENSITY image to organize points of input point cloud. Makes sense for unorganized input only.

◆ dwPointCloudRangeImageCreator_getCUDAStream()

DW_API_PUBLIC dwStatus dwPointCloudRangeImageCreator_getCUDAStream	(	cudaStream_t *	stream,
		dwConstPointCloudRangeImageCreatorHandle_t	obj
	)

Gets CUDA stream of range image creator.

Parameters

[out]	stream	Pointer to CUDA stream handle
[in]	obj	Handle to range image creator

Returns: DW_SUCCESS
DW_INVALID_ARGUMENT if given stream pointer is invalid
DW_INVALID_HANDLE If given handle is valid

◆ dwPointCloudRangeImageCreator_getDefaultParams()

DW_API_PUBLIC dwStatus dwPointCloudRangeImageCreator_getDefaultParams ( dwPointCloudRangeImageCreatorParams * params )

Gets default range image creator parameters.

Parameters

[out] params Pointer to range image creator parameters

Returns: DW_SUCCESS
DW_INVALID_ARGUMENT if given param pointer is invalid

◆ dwPointCloudRangeImageCreator_getImageProperties()

DW_API_PUBLIC dwStatus dwPointCloudRangeImageCreator_getImageProperties	(	dwImageProperties *	imageProperties,
		dwConstPointCloudRangeImageCreatorHandle_t	obj
	)

Get properties of an image to bind as an output.

Parameters

Returns: DW_SUCCESS
DW_INVALID_HANDLE If given handle is valid
DW_INVALID_ARGUMENT If imageProperties in null

◆ dwPointCloudRangeImageCreator_initialize()

DW_API_PUBLIC dwStatus dwPointCloudRangeImageCreator_initialize	(	dwPointCloudRangeImageCreatorHandle_t *	obj,
		const dwPointCloudRangeImageCreatorParams *	params,
		dwContextHandle_t	ctx
	)

Initializes range image creator.

Parameters

[out]	obj	Pointer to range image creator handle
[in]	params	Pointer to range image creator parameters
[in]	ctx	Handle to the context

Returns: DW_SUCCESS
DW_INVALID_ARGUMENT If given parameter pointer is invalid
DW_INVALID_HANDLE If given handle is valid

◆ dwPointCloudRangeImageCreator_process()

DW_API_PUBLIC dwStatus dwPointCloudRangeImageCreator_process ( dwPointCloudRangeImageCreatorHandle_t obj )

Organizes input point cloud and projects on the spherical coordinate to form a range image.

If bound point cloud is already organized, the data is simply copied into output range image.

Parameters

[in] obj Handle to range image creator

Returns: DW_SUCCESS
DW_INVALID_HANDLE If given handle is not valid
DW_CALL_NOT_ALLOWED If no input/output buffer is bound

◆ dwPointCloudRangeImageCreator_release()

DW_API_PUBLIC dwStatus dwPointCloudRangeImageCreator_release ( dwPointCloudRangeImageCreatorHandle_t obj )

		dwPointCloudRangeImageCreatorHandle_t	obj
	)

Sets CUDA stream of range image creator.

Parameters
