Abstract: Image-assisted total stations (IATSs) have extensive application prospects in astronomic surveys, deformation monitoring, precision engineering surveying, and topographic mapping. During image processing of data, the angle ...

Abstract: Precise determination of the astronomical azimuth using the local hour angle (LHA) of Polaris is only applicable in northern middle latitudes. Therefore, to achieve fast and precise astronomical orientation in any part of ...

Abstract: Astronomic positioning and orientation can be used to obtain the astronomic longitude and latitude of a station and the astronomic azimuth of a ground target by observing stars. The results of the positioning and orientation ...

Abstract: Utilizing charge-coupled device (CCD) imaging technology in astronomical surveying and positioning facilitates high-precision measurements without manual observation. This eliminates the influence of the traditional celestial ...
