hi_fisheye_attr

HI_FALSE: no
HI_TRUE: yes. This option takes effect only when the VPSS group ID is within the range [256, 268).

Description

Defines the configuration related to the fisheye attribute (XY mode).

Members

Member	Description
lmf_en	Whether to use the user-defined LMF parameter of the fisheye lens The options are as follows: HI_FALSE: no HI_TRUE: yes. This option takes effect only when the VPSS group ID is within the range [256, 268).
bg_color_en	Whether to attach the background color to the output image. This member can only be set to HI_FALSE. The options are as follows: HI_FALSE: disabled. HI_TRUE: enabled.
bg_color	Background color, in RGB888 format. Value range: [0, 0xFFFFFF].
hor_offset	Horizontal offset of the lens center point relative to the sensor center point. Value range: [–511, 511], in pixels. The lens center point must be a valid pixel in the image.
ver_offset	Vertical offset of the lens center point relative to the sensor center point. Value range: [–511, 511], in pixels. The lens center point must be a valid pixel in the image.
trapezoid_coef	Trapezoid correction coefficient. This member is used to correct the pitch angle in wall mount mode. Value range: [0, 32].
fan_strength	Fan correction strength coefficient, valid only in the 180° mode. Value range: [–760, 760].
mount_mode	Mount mode of the fisheye lens
rgn_num	Number of correction regions of an image. A maximum of four regions are supported.
fisheye_rgn_attr	Attribute configuration for each correction region.
