Statistical Methods in Surveying by Trilateration
Trilateration techniques use distance measurements to survey the spatial coordinates of unknown positions In practice distances are measured with error and statistical methods can quantify the uncertainty in the estimate of the unknown location Three methods for estimating the three dimensional position of a point via trilateration are presented a linear least squares estimator an iteratively r...
متن کاملSynchronised Data Acquisition for Sensor Data Fusion in Aerial Surveying
An existing facility for data acquisition in aerial surveys is presented. It contains a laser radar, an infrared camera and a video camera. The system supports synchronisation of sensor data, even when the sensor does not inherently offer that feature. This allows data from different sensors to be merged and processed together. The necessary temporal referencing is achieved by specialised hardw...
متن کاملLow Cost Surveying Using an Unmanned Aerial Vehicle
Traditional manned airborne surveys are usually expensive and the resolution of the acquired images is often limited. The main advantage of Unmanned Aerial Vehicle (UAV) system acting as a photogrammetric sensor platform over more traditional manned airborne system is the high flexibility that allows image acquisition from unconventional viewpoints, the low cost in comparison with classical aer...
متن کاملUnmanned Aerial Vehicle Instrumentation for Rapid Aerial Photo System
This research will proposed a new kind of relatively low cost autonomous UAV that will enable farmers to make just in time mosaics of aerial photo of their crop. These mosaics of aerial photo should be able to be produced with relatively low cost and within the 24 hours of acquisition constraint. The autonomous UAV will be equipped with payload management system specifically developed for rapid...
