The approach that gathers forestry diameter by camera image is introduced in detail and the error-in-measure models algorithm is successfully applied to the parameters resolving. While the inner parameters and outer parameters decomposing maneuver that is fit to forestry fieldwork is provided. The algorithm and maneuver in this paper are illustrated finally. Results prove:1) The way that reconstructing forestry diameter from camera images is available; 2) It's a good algorithm that parameters are resolved by error-in-measure models algorithm; 3) Decomposing camera inner parameters and outer parameters not only decreases the heavy forestry field work but also ensures the 3D reconstructing precision; 4) Considering the camera focus length independently, the flexibility of practical operation is improved.
