Method for judging terminal installation condition of road transport vehicle satellite positioning system

The invention discloses a method for judging the terminal installation condition of a road transport vehicle satellite positioning system. The method comprises the following steps: acquiring track data of vehicle satellite positioning; carrying out data abnormal point detection filtering and preprocessing; performing feature extraction and selection on the trajectory data; judging the use condition of the terminal in the window period endpoint range; judging the use condition of the terminal in the window period process range; and judging terminal installation situation. The trajectory data acquired by the terminal is used, the characteristics are extracted to describe the use condition of the terminal in the window period after the data is cleaned and filtered, and finally the installation condition of the road transport vehicle to the terminal is judged. The method can be applied to various applications related to driving behaviors, the reliability of data can be guaranteed on the premise that the installat
