| Abstract: | The principle of vehicle terminal combination positioning is introduced, and several methods for verifying the positioning accuracy of positioning of the terminal are proposed, including static positioning test, dynamic positioning test and general inspection. Experiments were carried out on the terminal to simulate the real scene. The experimental data of static state, occlusion environment, and road test were processed and compared with high-precision data to calculate the RMS “root mean square”of the terminal location (Root Mean Square). RMS), and matching the positioning data to the electronic map, showing good positioning and map matching results, based on theory,which conclude that the accuracy of terminal positioning meets the requirement of practical application. |
