Description

lmf_coef

LMF parameter of the fisheye lens.

#define HI_FISHEYE_LMF_COEF_NUM                128

The LMF parameters must be converted based on the parameters recommended by the lens vendor before being configured (the correct LMF parameters comply with the rule of lmf_coef[i+1] ≥lmf_coef[i]+5&& lmf_coef [i + 1] <= lmf_coef [i] + 31 && lmf_coef [57] <1024< lmf_coef [85] &&lmf_coef[0] = 0). If the configured parameters do not comply with the rule, an error is reported. If the configured parameters are incorrect, exceptions such as bus errors may occur. If there is no parameter provided by the lens vendor, you are advised to disable the LMF function.
