Members

Member	Description
imp_conf	Structure parameter of the concatenation table. The concatenation table data needs to be constructed based on the hi_stiching_ipm_table structure, which is compatible with the earlier version.
gain_conf	Gain compensation parameters. If gain compensation is not required, set the gain_type member in this data structure to GAIN_NONE.
lut_conf	Stitching table structure parameter. The stitching table data needs to be constructed based on the hi_roundview_stitching_lut_type1 structure. This type is more hardware-friendly and has better performance.
stitch_table_type	Stitching table type. Value range: 0: indicates the combination table of the hi_stiching_ipm_table type. The hi_stiching_ipm_table-type stitching table structure is open to users. You can call the hi_mpi_vpc_set_roundview_stitching_param API to set the parameters of the hi_stiching_ipm_table-type stitching table. However, the DVPP converts the hi_stiching_ipm_table-type stitching table into the hi_roundview_stitching_lut_type1-type stitching table. The conversion operation may affect the performance. 1: indicates the combination table of the hi_roundview_stitching_lut_type1 type. The hi_roundview_stitching_lut_type1 stitching table structure is open to users. You can call the hi_mpi_vpc_set_roundview_stitching_param API to set the parameters of the hi_roundview_stitching_lut_type1 stitching table.
mini_order	Whether the stitching table is of the compact type. On the 0: non-compact type. No sampling is performed. 1: compact type.
chassis_conf	Transparent chassis configuration.
reserved	Reserved. To ensure compatibility in later versions, use the memset structure for resetting and initialization. Do not explicitly access the reserved field in the code.
