PTK_Alg_StereoPP_DisparityMergeSetParams()

void PTK_Alg_StereoPP_DisparityMergeSetParams	(	PTK_Alg_StereoPP_DisparityMerge_configParams *	cfg,
		PTK_Alg_StereoPP_DisparityMergeObj *	cntxt
	)

Initialize disparity merge parameters.

Parameters

[in]	cfg	configuration parameters for disparity merge
[in]	cntxt	hole filling algorithm context

Returns

PTK_Alg_StereoPP_DisparityMergeConfig()

int32_t PTK_Alg_StereoPP_DisparityMergeConfig	(	PTK_Alg_StereoPP_DisparityMerge_configParams *	cfg,
		PTK_Api_MemoryReq *	memReq
	)

Computes the memory requirements based on the given algorithm configuration parameters.

Parameters

[in]	cntxt	Algorithm configuration parameters.
[in]	memReq	Memory requirements as specified below entry [0]: Memory for internal context. Best allocated from the fastest memory. entry [1]: Memory for internal point cloud. Best allocated from the fastest memory. entry [2]: Memory for the output buffer. The output buffer is allocated by the Application so this entry is just to communicate the output buffer size. No need to pass the memory to the library in the init call PTK_Alg_SfmOgmapInit().

Returns

• PTK_ALG_RET_SUCCESS, if successful
• < error code, otherwise

PTK_Alg_StereoPP_DisparityMergeInit()

PTK_AlgHandle PTK_Alg_StereoPP_DisparityMergeInit	(	PTK_Alg_StereoPP_DisparityMerge_configParams *	cfg,
		const PTK_Api_MemoryRsp *	memRsp
	)

Initializes the library based on the given algorithm configuration parameters and allocated memory blocks.

Parameters

[in]	allParams	Algorithm configuration parameters.
[in]	memRsp	Memory blocks as specified below

Returns

• valid handle, if successful
• NULL, otherwise

PTK_Alg_StereoPP_DisparityMergeGetMem()

int32_t PTK_Alg_StereoPP_DisparityMergeGetMem	(	PTK_Alg_StereoPP_DisparityMergeObj *	cntxt,
		uint8_t *	memPtr
	)

Get memory size.

Parameters

[in,out]	cntxt	Algorithm handle.
[in]	memory	block pointer

Returns

• required memory size

PTK_Alg_StereoPP_mergeDisparity()

		int16_t *	disparityHighBuffer,
		int16_t *	outDisparityBuffer,
		int16_t	lowBufferStride,
		int16_t	highBufferStride
	)

Merge two disparity maps.

Parameters

[in]	cntxt	algorithm handle
[in]	disparityLowBuffer	input lower-resolution disparity buffer
[in]	disparityHighBuffer	input higher-resolution disparity buffer
[out]	outDisparityBuffer	output disparity buffer
[in]	lowBufferStride	stride of lower-resolution disparity buffer
[in]	highBufferStride	stride of higher-resolution disparity buffer

Returns

		int16_t	loWidth,
		int16_t	loStride,
		int16_t	loHeight,
		int16_t	hiWidth,
		int16_t	hiStride,
		int16_t	hiHeight,
		int8_t	loDispOnlyFlag
	)
