Positioning the scanner correctly leads tocapturing all required scan data in the most efficient manner possible.There are several factors to consider when selecting scanner positions,including:• Number of scanner positions• Distance from the object or area of interest• Line of sight• Angle to the object of interest• Bisecting• Target arrangementsThe primary concern when selecting scanner positions is capturing theobject of interest.NMmbMM Mf LMMMMMM MMLMMMMMLEach project will differ in the project requirements and constraints, andthe number of scanner positions will depend on these factors, as well ason site and environmental conditions. With careful planning, you canminimize the number of scanner positions needed to adequately capturethe object or area of interest.The most important factor to consider when determining the number ofscanner positions is overlapping scan areas. Each scan area must overlapwith one or more other scan areas to ensure successful registration.DMLMMMMM fMMm MhM ObMMMM MM AMMM Mf IMMMMMLMThe maximum allowable distance between the scanner and the objectof interest depends on the desired level of detail, time constraints, siteconditions, and other factors.Slides 102-104Slide 105Slides 106-107
