Members

Member	Description
imp_conf	Stitching table structure parameter. The stitching table data must be constructed based on the hi_stiching_ipm_table structure. It is compatible with earlier versions.
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 must be constructed based on the hi_roundview_stitching_lut_type1 structure. This type is more hardware-affinity and has better performance.
stitch_table_type	Stitching table type. The options are as follows: 0: hi_stiching_ipm_table type. The structure of stitching tables of the hi_stiching_ipm_table type is open to users. You can call hi_mpi_vpc_set_roundview_stitching_param to set the parameters of a stitching table of the hi_stiching_ipm_table type. However, DVPP will convert the stitching table into a table of the hi_roundview_stitching_lut_type1 type, which may affect the performance. 1: hi_roundview_stitching_lut_type1 type. The structure of stitching tables of the hi_roundview_stitching_lut_type1 type is open to users. You can call hi_mpi_vpc_set_roundview_stitching_param to set the parameters of a stitching table of the hi_roundview_stitching_lut_type1 type.
mini_order	Whether the stitching table is of the compact type. 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.
