Abstract

In this paper, the mathematical model of three-dimensional geometric transformation and multi-objective programming is established based on the changing law of the solar shadow, which is combined with geographical and geometric knowledge. Using the least square method and Matlab software, determine the possible location and date of the straight pole.
