Software Development Services Stellar Science primarily provides software development services under contract to government or commercial clients. However, this page describes some of the commercial products we offer, many of which were spin-offs from SBIR or other development contracts that allow for product commercialization. Escalator Plugins NITF Escalator J2K Escalator ECW Escalator Caliper - Image Based Mensuration Caliper is a software tool that allows users to extract 3D measurements from a series of 2D images. Caliper’s user-friendly interface helps users specify 2D image-to-image correspondences. The tool then uses Stellar Science’s proprietary shape from motion engine to calculate the 3D distances between each pair of user identified features. Please see the Air Force’s SBIR Innovation Writeup. 3D Web Viewing Given a real world object, Stellar Science can create a 3D model that can be incorporated into any webpage. We start by using a laser scanner to create a colored 3D mesh. We then export the mesh into a web format for display within our custom 3D web viewer applet. Our web viewing applet works on virtually every platform and browser combination and it does not require any special 3D browser plug-ins. Please check out our 3D Web Gallery for samples. Satellite Shape From Motion Working under an Air Force SBIR phase II contract, Stellar Science sought to apply the latest shape from motion (SFM) computer vision algorithms to the space situational awareness (SSA) domain. The goal of this research project was to compute the three-dimensional (3D) shape and orientation of a satellite from two-dimensional (2D) images of it. SSA imagery presents some unique challenges and advantages for solving the shape from motion problem. By combining a number of techniques from computer vision and computer graphics, Stellar Science demonstrated the feasibility of automatically constructing a satellite model from an uncalibrated sequence of space surveillance images. Our website presents one successful test case. The computational process involves 2D feature tracking and matching, linear factorization, non-linear optimization, outlier rejection, background-foreground segmentation, volumetric shape carving, alpha shape facetization, and hardware-accellerated multi-texture mapping. CAPCO Classification Manager CCM is a library for managing, marking, and merging U.S. Government and foreign government security classification strings. It supports the official Controlled Access Program Coordination Office (CAPCO) standard for document marking and includes collateral, FGI, SCI, SAR, and other marking types.
