N2 - Important objects of natural environment, ecologic landscapes, as well as big engineering constructions, require geometrical monitoring to predict its structural health during their lifetime. That monitoring by geodetic devices, wireless networks or GPS technology is not always optimal; sometimes it is impossible as shown. The method based on geodetic measurements automation applying local optical scanners for monitoring in natural environment is proposed. It is based on the novel method of plane spatial angles precise measurement. It consider robust invariant AD-conversion angle-to-code for instant dynamic angle, signal energetic center search method, initial reference scale adjustment, and uncertainty decrease by mediant fractions formalism for result approximation. It is described system parts interaction for spatial angle encoding with beforehand set accuracy. Method is appropriable for uncertainty reduction limited only by reasonable ratio “uncertainty/operation velocity”. The operation range, accuracy, scanners operation velocity, and its adoptions on the objects were described. Presented experimental results confirms that in front of passive scanning aperture our system overcomes main recently known optical devices for 3D coordinates recognition in offset uncertainty.
