Trigger-to-Image Reliability ensures highly reliable acquisition control throughout the image capture and processing sequence, from the time that a trigger is fi red (part in place), to the time the image is transferred to the host computer for processing, to the time a decision is made to accept or reject the part. This level of dependability is accomplished by integrating various image acquisition control functions - including trigger inputs, strobe outputs, camera control signals and external I/O - onto on-board hardware and using software API functions for command and control. CamExpert offers live image display, camera signal status and powerful image analysis functions to ease system setup, calibration and diagnostics. RAPID DEVELOPMENT USING .NET AND APPLICATION WIZARD Support for .NET platform within Sapera Essential, permits rapid application development using Microsoft Visual Basic, C#, or C++ programming languages. Sapera Essential .NET supports image acquisition, control, display, image processing, calibration, color, barcode, blob analysis and area and shape based search functions. Sapera Essential includes a Microsoft Visual Studio 6.0 compatible application wizard to kick start the development process and shortens the learning curve. The Sapera Essential wizard supports both area and line scan cameras and generates code that conforms to DALSA’s Trigger-to-Image Reliability framework to control and monitor the image acquisition and transfer process. The Sapera Essential wizard allows operators to quickly create an image application project using various Sapera Essential components. CALIBRATION Calibration tool provides functions to compensate for geometrical distortions caused by camera lens, camera positioning or any other kind of arbitrary image distortion. COLOR TOOL The color tool is composed of a series of classes for color processing and analysis on a variety of color formats such as RGB, YUV, HSV and LAB. The tool provides comprehensive functionality in many applications like food, wood, automotive and electronics, offering color calibration and correction, color identifi cation and classifi cation, basic image processing, pattern matching and color space conversions. ™ BLOB ANALYSIS Blob Analysis allows for the separating (segmenting) of objects in a scene from the background and then computes a series of geometric and grayscale features. Blob analysis is ideal for defect detection in the electronic and semiconductor industries.Tool features: ? Supports 1-bit, 8-bit, 16-bit, binary or grayscale input images? Different levels of input (grayscale image, binarized or labeled image)? Calculation of over 50 spatial and grayscale blob features CAMEXPERT CAMERA CONFIGURATION UTILITY Sapera comes bundled with CamExpert; an enhanced proprietary camera confi guration utility. This Windows- based program provides an interactive environment to create new or modify existing confi guration fi les for area and line scan applications. Features include:Key Features? Enhanced Graphical User Interface with camera centric parameters? Live grab and display window for online parameter fi ne tuning? Sophisticated waveform display improves understanding of signal inter-relationships OCR TOOLS The OCR tool is a set of intuitive classes intended to ensure the industry’s most reliable OCR functionality. The tool offers a high degree of freedom in font selection and is particularly effective in applications with problematic character degradation and poor illumination. Two complementary algorithms offer developers maximum fl exibility in a wide range of applications such as document imaging, semiconductor, automotive and pharmaceuticals. Fine tune search parameter to achieve maximum throughput without compromising accuracy and repeatability. Geometric Search BARCODE The barcode tool is a set of functions used to decode 1-D and 2-D barcodes and provide support for a variety of standard codes commonly used in the industry. Designed to operate on degraded and poorly illuminated images, the image-based barcode tool performs signifi cantly faster than a laser-based scanner and gives you the fl exibility to operate in tandem with other tools such as Search. Sapera Essential barcode tool uses sub-pixel accuracy for symbology detection and decoding and can output decoded strings in Asian native languages or as Unicode characters. SEARCH (PATTERN FINDING) TOOL Area-based? Algorithm based on normalized cross-correlation (NCC)? Extremely fast when no scaling is involved? Tolerant to extreme noise ? Position accuracy up to 1/25th pixel Edge-based? Algorithm based on object contours? Rotation and contrast independent ? Position accuracy up to 1/50th pixel ? Angle accuracy up to 1/80th degree ? Locates up to 5 instances of target in the target image Barcode SAPERA FUNCTIONALITY Sapera Essential provides support for a variety of standard codes commonly used in the industry. IMAGE PROCESSING AND ANALYSIS LIBRARIES Sapera Essential includes a suite of highly optimized basic image processing functions categorized in several groups including:? Filters? Geometry ? Measurement ? Morphology ? Point-to-Point ? Transforms ? Miscellaneous features (including sub-pixel edge crossing on a pat, contour following and frame averaging - true and recursive)
