The first version of OrthoGraph was released in 2004 for PDA devices. An iPad version of the application was released in 2011. [1] [2]In 2013, a cooperation agreement was established between OrthoGraph and Leica, so that several Leica laser distance meters were supported by OrthoGraph's application.
Measurement of distance is accomplished with a modulated infrared carrier signal, generated by a small solid-state emitter within the instrument's optical path, and reflected by a prism reflector or the object under survey. The modulation pattern in the returning signal is read and interpreted by the computer in the total station.
While the initial release of IMAGINE Photogrammetry (called "Leica Photogrammetry Suite 8.7") was in late 2003, it was a combination of new technology as well as software previously developed by ERDAS (which was acquired by Leica Geosystems in 2003). The product evolution is as follows: 1991 - "Digital Ortho" in ERDAS 7.5; 1993 - OrthoMAX
The brand Leica, better known for Leica Cameras, was formed on 2 April 1990 after the merger of several companies.In 2005, the company was acquired by Hexagon AB.Leica was listed on the Swiss stock exchange until the 7 August 2006 which saw the cancellation of all publicly held registered shares in Leica Geosystems Holdings Ltd and delisting of all listed registered shares of a par value of ...
Typical distance measurements were between mountain tops. The tellurometer design yields high accuracy distance measurements over geodetic distances, but it is also useful for second order survey work, especially in areas where the terrain is rough and/or the temperatures extreme.
Time of flight of a light pulse reflecting off a target. A time-of-flight camera (ToF camera), also known as time-of-flight sensor (ToF sensor), is a range imaging camera system for measuring distances between the camera and the subject for each point of the image based on time-of-flight, the round trip time of an artificial light signal, as provided by a laser or an LED.
CloudCompare is a 3D point cloud processing software (such as those obtained with a laser scanner).It can also handle triangular meshes and calibrated images. Originally created during a collaboration between Telecom ParisTech and the R&D division of EDF, the CloudCompare project began in 2003 with the PhD of Daniel Girardeau-Montaut on Change detection on 3D geometric data.

David Hall founded Velodyne in 1983 as an audio company specializing in subwoofer technology. [9] [10]Velodyne's experience with laser distance measurement started in 2005, when David Hall and his brother Bruce (then president of Velodyne) entered a vehicle in a driverless car race called DARPA Grand Challenge sponsored by the Defense Advanced Research Projects Agency (DARPA).
