摘要：

We will have the date and time and put it into the model of the relationship between the solar height angle and local time, to obtain the length of the shadow of the functional relationship between theoretical value and observed latitude. We divide the length of the shadow of two adjacent times to eliminate the length of the pole. We minimize the error between the theoretical and actual values of the ratio of the length of the adjacent shadow to the objective function, and then use the search method to determine the minimum error of the straight rod location and local time.
