Image Acquisition
Sapera LT SDK provides field proven functions and libraries for image acquisition from a wide variety of area and linescan color/monochrome cameras and our 3D laser Profiler. Sapera LT SDK support all major machine vision standard such as CameraLink, CameraLink HS, CoaXpress, USB3 Vision, and GigE Vision. Sapera LT features a highly optimized GigE Vision driver that incorporate Teledyne DALSA’s patented TurboDrive™ technology to augment the GigE image transfer speeds by a factor of x1.5 to x3. When coupled with supported hardware cameras, this breakthrough technology delivers additional bandwidth to imaging applications without additional programming steps or resource utilization.
The image acquisition libraries are designed for high performance vision applications in mind and offer sophisticated host image buffer and transfer management techniques. Sapera LT SDK and its re-distributable runtime components for application deployment are offered free of charge when used with Teledyne DALSA cameras and frame grabbers.

Below are demos & examples available with the Sapera LT SDK:
| Demo Type | Name | Description |
| GUI Based | ColorConversion Demo | This demo show color conversion functionalities including Bayer pattern, BiColor (linescan) and more. |
| GUI Based | GigECameraDemo | This demo shows how to acquire images from a Teledyne DALSA GigE Vision™ camera. The demo either loads a configuration file (previously generated by CamExpert) or uses the camera defaults |
| GUI Based | GrabDemo | This demo shows the basic acquisition functions included in Sapera LT ++. It allows you to acquire images either in continuous or in one-shot mode, while adjusting the acquisition parameters. |
| GUI Based | FlatFieldDemo | This demo shows how to use the flat field correction function included in Sapera LT ++. Flat Field Correction (FFC) includes Fixed Pattern Noise (FPN), Pixel Replacement, Photo Response Non-Uniformity (PRNU), and Shading Correction |
| GUI Based | MultiBoardSyncGrabDemo | This demo shows how to grab from two different frame grabbers simultaneously (SapAcquisition servers), place both images in a single buffer, and display it |
| GUI Based | IODemo | This demo shows the usage of General I/O functionality included in Sapera LT ++. It allows you to monitor the current state of the input and output pins and change their state between low and high polarity |
| GUI Based | GigEMetaDataDemo | This demo shows the metadata functionality supported by Teledyne DALSA GigE Vision™ cameras |
| GUI Based | SeqGrabDemo | This demo shows how to grab a sequence of images from a camera into memory and then display them. The program allows you to record several images and save AVI files, plus load those AVI files for playback |
| Console | CameraEvents | Shows how to list all the available events with the camera. Using the registering and unregistering callback mechanism, it shows also how to track when a specific T2IR event occurs. |

T2IR
Sapera LT features Teledyne DALSA’s Trigger-To-Image-Reliability framework. T2IR is a set of programmable functions within the Sapera libraries that supports the real-time traceability of the image acquisition and transfer process. Developers can build detection, monitoring, diagnostic and prevention capabilities directly into their application for seamless operations. T2IR combines hardware and software functions including visual indicators on the hardware, software libraries and stand-alone, non-intrusive utilities that can run transparently alongside the user applications without modifications.
Development Platforms and Tools
Sapera LT SDK image acquisition and control libraries are hardware independent and allow seamless interchangeability among Teledyne DALSA cameras and/or frame grabbers. Modular in nature, Sapera LT applications can be developed using Microsoft® C/C++, C# with Microsoft .NET™ framework & .NET™ platform. Sapera LT is supported on Microsoft Windows 10 and Windows 11 64-bit platforms.
