Functions

Obtains surround-view stitching parameters, including table stitching and gain compensation parameters.

Before calling this API, call the hi_mpi_vpc_set_roundview_stitching_param API to set the surround-view stitching parameters. Otherwise, an error is returned.

If mini_order is set to 1 (indicating the miniaturized type) by calling the hi_mpi_vpc_set_roundview_stitching_param API, the surround-view stitching parameters cannot be obtained by calling this API.

Prototype

hi_s32 hi_mpi_vpc_get_roundview_stitching_param(hi_vpc_chn chn, hi_roundview_stitching_param *stitch_param)

Parameters

Parameter	Input/Output	Description
chn	Input	Channel ID for image processing.
stitch_param	Input/Output	Surround-view stitching parameters. The float-type parameter value in imp_param.ipm_table_address of the command output has a floating-point precision difference (not greater than 0.01) from the input parameter.
