Member	Description
src_pic_width	Width of the input image. The widths of the four input images must be the same.
src_pic_height	Height of the input image. The heights of the four input images must be the same.
dest_pic_width	Width of the output image.
dest_pic_height	Height of the output image.
lut_table_len	Memory size of the LUT table.
lut	Indicates the address of the LUT table. The memory size may be large. If the malloc interface in the C standard library is directly used to allocate memory, the memory will be fragmented and the number of huge pages will be reduced. As a result, the input/output memory of each DVPP function cannot be allocated by using the hi_mpi_dvpp_malloc interface. Therefore, you are advised to use the hi_mpi_dvpp_malloc API to allocate memory for storing LUTs.
mask_len	Reserved The value is fixed at 0.
mask	Reserved Currently, the value is fixed to NULL.
blend_table_len	Memory size of the blend table. Surround-view stitching: The value of blend_table_len is = dest_pic_height * dest_pic_width. Surround-view stitching + transparent chassis: The value of blend_table_len is = dest_pic_height * dest_pic_width * (1+1/4+1/16+1/64+1/256+1/1024). There are six blend tables in total. Each table is obtained after the previous one is downsampled by the Gaussian pyramid. The width and height of each table are half of those of the previous one.
blend_table	Blend table address.
reserved	Reserved The value is fixed at 0.
