Resection method for direct georeferencing in Terrestrial Laser Scanner
Journal of Mining and Earth Sciences, 2022 Recently, the direct georeferencing method has been increasingly used in Terrestrial Laser Scanner (TLS). This method has the benefit of saving time, but the low accuracy is a great difficulty to use. This paper proposed a possible approach for direct georeferencing with high accuracy using the resection method.
