Embodiment Construction
[0069] The present invention will be further described below in conjunction with the accompanying drawings.
[0070] Such as figure 1 Shown is the schematic diagram of the method of the present invention.
[0071] First establish the horizontal ellipsoidal model and on this basis establish the horizontal ellipsoidal coordinate system e′, the horizontal geographic latitude and longitude and the horizontal geographic coordinate system g′, and then establish the horizontal wandering coordinate system T based on the horizontal geographic coordinate system g′, the specific position relationship like figure 2 shown; image 3 The relationship between the angles involved in the present invention is given, X T Axis, Y T The axes are the two axes in the lateral movement coordinate system T, X b Axis, Y b The axes are respectively the horizontal axis (pointing to the right) and the vertical axis (pointing to the front) of the body coordinate system b, X g′ Axis, Y g′ The axes ar...
