ICam

The ICam Photogrammetry systems are high-accuracy portable CMM’s. They can be used to determine the 3D coordinates of targets, of points materialized with adapters as well as of features. The system is extremely portable, i.e. the measurement system comes to the work piece. The ease of use, flexibility, speed, and accuracy unsurpassed. Even very large objects like ships and bridges can be measured.

The system consists of a camera, coded and un-coded targets, scale bars and for certain applications various adapters. For the measurement the points of interest are targeted. Adapters are placed in holes and other reference locations such as edges. Finally coded targets are attached and the scale bars are placed. Then a set of images is acquired with the digital camera. These are typically transferred to a computer for processing. The software will detect the coded and non-coded targets, compute the orientation of all the images, label the non-coded targets, compute precise 3D coordinates together with the calibration of the camera, and perform the scaling as well as transformation into the coordinate system of the part. The coordinate system can be defined in a number of ways, either using a 3-2-1 alignment, reference values for the targets or adapters, or geometric primitive elements. The data can be used for an inspection and comparison to CAD, deformation or movement analysis, and crash test investigation. It is a perfect tool for part placement repeatability studies. High accuracy target networks can be provided for scanning systems.
