7. What is HexSight HexSight is a comprehensive library of machine vision tools available as ActiveX controls C DLL libraries or a NET DLL assembly At the heart of HexSight the unique and powerful Locator tool provides accurate and robust object recognition through geometric object location The Locator finds the contours of parts in the image and quickly identifies each part s position and orientation This information can be sent to a robot or machine controller to guide part handling In addition HexSight provides integrated calibration and a complete set of inspection tools HexSight tools can be model based to leverage the Locator s results by automatically transposing tools on parts regardless of their scale or rotation HexSight Quick Start Guide Location Transform Configuration Fest 2nd Edge Scor Polarity Dak toi light to Either Score Thresh System Requirements To run HexSight on your computer the Hardware Requirements following hardware and software are f e Processor Pentium II or higher required e Hard Drive space From 15 MB to 200 Software Requirements MB depending on selected components e Operating system Windows XP with Service Pack 3 Windows Vista x86 or x64 or Windows 7 x86 or x64 e Display Minimum resolution 1024 x 768 pixels Colors 65 536 e Memory RAM 128 MB e Visual Studio NET 2003 or higher or other Activ
