Function Documentation

PTK_Alg_FusedOgmapGetMapConfig()

void PTK_Alg_FusedOgmapGetMapConfig	(	const PTK_Alg_FusedOgmapParams *	cfgParams,
		PTK_MapConfig *	config
	)

Initializes the map configuration based on the given algorithm configuration parameters.

Parameters

[in]	cfgParams	Algorithm configuration parameters.
[out]	config	Map configuration

PTK_Alg_FusedOgmapConfig()

int32_t PTK_Alg_FusedOgmapConfig	(	const PTK_Alg_FusedOgmapParams *	cfgParams,
		PTK_Api_MemoryReq *	memReq
	)

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

Parameters

[in]	cfgParams	Algorithm configuration parameters.
[out]	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_FusedOgmapInit().

Returns

• PTK_ALG_RET_SUCCESS, if successful
• < error code, otherwise

PTK_Alg_FusedOgmapInit()

PTK_AlgHandle PTK_Alg_FusedOgmapInit	(	const PTK_Alg_FusedOgmapParams *	cfgParams,
		const PTK_Api_MemoryRsp *	memRsp
	)

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

Parameters

[in]	cfgParams	Algorithm configuration parameters. It is ecpected that the same configuration parameters passed in the PTK_Alg_FusedOgmapConfig() API are given. No check can be made to make sure these are the same. Failure to provide the same parameter set might result in an unexpected behavior (ex:- memory requirements could be different for different parameter set).
[in]	memRsp	Memory blocks as specified below entry [0]: Memory for internal context. entry [1]: Memory for internal point cloud.

Returns

• valid handle, if successful
• NULL, otherwise

PTK_Alg_FusedOgmapProcess()

int32_t PTK_Alg_FusedOgmapProcess	(	PTK_AlgHandle *	algHandle,
		PTK_Alg_FusedOgmapParams *	cfgParams,
		const PTK_Grid *	cameraGrid,
		const PTK_Grid *	radarGrid,
		const PTK_Grid *	lidarGrid,
		PTK_INS_Record *	insRec,
		const PTK_RigidTransform_d *	Md_ecef_w,
		PTK_Grid *	outGrid,
		PTK_Grid *	fusedDSGrid
	)

Processes the given point cloud and performs the Occupancy grid mapping.

Parameters

[in,out]	algHandle	Algorithm handle.
[in]	cfgParams	Configuration parameters.
[in]	cameraGrid	OGMAP grid from camera processing
[in]	radarGrid	OGMAP grid from radar processing
[in]	lidarGrid	OGMAP grid from lidar processing
[in]	insRec	INS record corresponding to the sensor maps.
[in]	insRec	INS record corresponding to the sensor maps.
[in]	Md_ecef_w	Transform from world to ECEF.
[out]	outGrid	Fused output OGMAP grid.
[out]	fusedDSGrid	Output Dempster-Shafer grid.

Returns

• PTK_ALG_RET_SUCCESS, if successful
• < error code, otherwise

PTK_Alg_FusedOgmapDeInit()

void PTK_Alg_FusedOgmapDeInit

(

PTK_AlgHandle

algHandle

)

De-initializes the algorithm context.

Parameters
