Embodiment Construction
[0040] The above and other technical features and advantages of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them.
[0041] Such as figure 1 As shown, a UWB base station coordinate automatic calibration method based on optimization theory includes the following steps:
[0042] S100: Layout the minimum UWB system, place the base stations A0, A1, A2 and tag T0 in the corresponding positions, see figure 2 ;
[0043] S200: Set point A0 as the origin of coordinates, and use the direction from point A0 to point A1 as the X-axis to establish a rectangular coordinate system;
[0044] S300: Read the initial coordinates of each point in the minimum UWB system, and at the same time, calculate the distance between any two points in the minimum UWB system;
[0045] S400: Substituting all distance values into...
