First, I can estimate LAI at several viewing zenith angles by the equation of Nilson 1971,utilizing digital photos taken from different angles . of course, it needs some assumption. Second, I would like to calculate the final LAI as the output value through above, however, I don't konw how to do this. Please someone help me .
Dear Li Linyuan,
Estimating LAI from multi-directional measurements in the canopy is the standard approach if the LAI-2000 instrument produced by Licor. Here is a brochure about that device:

You may also want to study the various publications of Dr. Inge Jonckheere, who is a specialist on this matter:

I hope this helps. Cheers, Michel.
