hi_mpi_vpc_get_remap_lut

The Atlas 200/300/500 Inference Product does not support this API.

The Atlas Training Series Product does not support this API.

Description

Based on the remap table (such as affine, perspective, and fisheye) input, the common Bilinear algorithm (similar to the computation process of the OpenCV algorithm) is used to obtain the pixel position remap table used by the system. This API is synchronous.

Prototype

hi_s32 hi_mpi_vpc_get_remap_lut(hi_map_param *map_param, hi_remap_lut *remap_lut)

Parameters

Parameter	Input/Output	Description
map_param	Input	Original map information of a user.
remap_lut	Input/Output	Pixel position remapping LUT. In the hi_remap_lut structure: When lut is used as an input, you must allocate memory in advance. The memory size lut_size can be obtained by calling hi_mpi_vpc_get_lut_mem_size. When lut is used as an output, you can obtain the affine transformation LUT information from the memory after this API is successfully called.

Returns

0: success
Other values: failure (VPC Return Codes)
