3D point cloud survey capture and assessment
The practice of surveying is essential in having both a successful planning stage and successful construction. In a modern fashion, surveying is used in the fields of mapping, communications, building and construction, legal boundary definitions, and transportation. Land surveying is a technique of accurately determining the three-dimensional position of points in space along with the distances and angles in-between them. To achieve a successful survey, it requires the elements of trigonometry, engineering, and mathematics working together to develop a reliable set of information pertaining to the actual condition of the area being analyzed. Automated drone technology is advancing and becoming more affordable by the day. A commercial drone when aided with an advanced camera sensor can yield very accurate results in a short amount of time. By flying the drone on a coordinated grid, one can program it to take sequenced photos while on the flight path. The flight path is set up to where there are overlapping areas with the photos taken. Using a specialty software, one can then take the georeferenced photos captured and convert them into a point cloud in the preferred BIM format. Analyzing the point cloud correctly will result in contour lines for the surveyed piece of land. This whole process yields the equivalent of a land survey via traditional methods in half the time and can be conducted with only one person being the Remote Pilot in Command.
