Embodiment
[0104] The inventor has carried out experiment with the inventive method and GPS positioning method, and experimental process is as follows:
[0105] The inventor conducted a test in a certain automobile proving ground. Using the above method, a gantry and a second camera were installed every 5km on the runway, and a gyroscope and an accelerometer were installed inside the vehicle to obtain the angular rate and acceleration, and installed on the outer section of the vehicle The first camera shoots the road surface, and the test is carried out using the above method. The final test results are as follows: Figure 6 shown. The line marked with a triangle is the trajectory obtained by this method, and the line marked with a circle is the actual trajectory of the vehicle. From Figure 6 It can be seen that the trajectory diagram of the triangle line and the circle line is almost completely consistent, which proves that the positioning effect is quite ideal, and the actual effect...
