I-SiTE’s new generation software I-SiTE Studio2.1 was released at the AURISA conference in South Australia in November. I-SiTE Studio is the essential link between today’s laser scanners and delivery of the useful results required by surveyors, engineers and investigators. It allows one to apply laser scanning technology to a diversity of industries, from mining to forensic science.
New to this release is the support for a wide range of other data formats. This means that you can work with a variety of laser scanners, using any data to its full effect, and even combining data from different sources. Data from the Optech ILRIS scanner can be imported seamlessly. Other input, such as from Callidus and Cyrax scanners, survey point text files, Optech CMS data and conventional CAD data or surface files can be imported and manipulated in I-SiTE Studio2.1.
I-SiTE Studio2.1 provides total field control, acquisition and downstream processing software for several Riegl laser scanners, including the LMS-Z210, LMS-Z360 and LMS-Z420. Colour data is displayed automatically along with the coordinated point data collected by these scanners.
Superior survey location tools integrate with your existing survey station libraries and a range of scan coordination techniques to ensure data is always accurately located, both with other scans and with real world coordinates. As well as proven field tools for locating scan data into local coordinate systems, I-SiTE Studio2.1 includes improved multiple scan registration. Automatic matching of scan data sets collected from different positions gives complete 3D coverage and seamless data registration in seconds. CAD or survey data can also be used as a base for registration, allowing users to easily match scans into existing plans or surveys.
Large point data sets can be efficiently interrogated, modeled and manipulated on a desktop PC or field laptop. Selected spatial data can be extracted from the point cloud as individual points, or as best fit planes through entire sections of the scan. Manipulation using advanced CAD and modelling tools creates easily exported CAD wireframe or string files, or solid surfaces.
Complex 3D surfaces can be generated from scan data. Surfaces can be fit to subsets of scan data and extended to meet other surfaces. Once surfaces required for detail are scanned, I-SiTE Studio2.1 builds a complete solid model. Modelling aids include mirroring of surfaces, fitting geometric shapes such as planes, circles and lines, and extrusion.
CAD linework can be generated by different methods. Traditional CAD tools allow the user to snap to a variety of data characteristics to create lines and polygons. Automatic edge detection tools can quickly produce a 3D line drawing from the registered raw scans in more detail than ever before possible. Standard shapes can be fitted and extruded along the scan data to build up models of geometric structures or buildings. Models and survey data can be annotated with 3D text. Building and structure elevations and footprints are produced as a bonus.
Contour generation tools allow users to create, name and colour major and minor contours for mapping and other applications. Calculation of surface cut/fill and solid volumes enables rapid analysis of stockpiles and excavations. It has been shown that the I-SiTE method of measuring stockpiles in 3D represents a time saving in the order of 10 to 1.
I-SiTE Studio2.1 will improve the efficiency of surveyors and engineers using laser scanning in any work environment.
