After the various consultants have poured over the shared copy of the point cloud, adjustments, additions and suggestions can be collaborated within the cloud.
The density of a point cloud is dependent on the quantity and quality of the photos taken, but also on the followed protocol of the shooting(7). Each point cloud is calculated by matching several photographs (in the case of photogrammetry survey) so as it corresponds to a point of the surface of the surveyed object. Number of Generated Tiles 1 / Number of 3D Densified Points 9441467 / Average Density (per m 3) 437.92Ī Point Cloud is the set of three-dimensional distributed points which result from a laser or photogrammetry scan.DSM and Orthomosaic Resolution 1 x GSD (1.86 ).Output Coordinate System WGS 84 / UTM zone 10N (egm96).Geolocation Orientational Variance RMS Omega 0.868 Phi 1.039 Kappa 2.454 (Geolocation RMS error of the orientation angles given by the difference between the initial and computed image orientation angles.).Average Ground Sampling Distance (GSD) 1.86 cm / 0.73 in.The total time aloft to collect all of this the aerial data was less than fifteen minutes.(6)
Each completed project generates a report that in conjunction with a survey team produces amazing accuracy and imagery.
The listed partial sampling of facts below are taken directly from the generated quality report within Pix4D for this dam. The final image above has included: DSM and Orthro images over a Google Earth map that is geolocated.
