Introduction

SAL3D is a development suite comprising a set of easy to use tools for the development of powerful applications oriented based on the processing and analysis of organized 3D data or Clouds of Points.

These tools are characterized by the speed, accuracy, and reliability that comes only from extensive experience in the field of 3D. SAL3D is offered to OEM's, system integrators, and volume end users demanding maximum flexibility and customization capabilities for their 3D machine vision system.

SAL3D allows both existing and new 3D vision algorithms to be incorporated in any SAL3D application. Tools can be integrated as DLL's easing developers access to third party components usable side by side with SAL3D's tools resulting in the rapid development of complex processing tasks.

SAL3D library can be used under Windows 2000, Windows XP, or newer on 32-bits or 64-bits. For other platforms, please, contact support@aqsense.com.

Warning:

There are two different installers, one for 32-bits operating systems and another for 64-bits systems. Make sure you use the corresponding installer

Some of SAL3D's features are:

• Easy to use C++ classes usable with most commercially available C++ compilers.
• Hardware acquisition independence through the use of frame grabber drivers.
• Open architecture suitable for extending SAL3D's algorithms with custom and third party components.
• Examples to help developers speed up in using SAL3D's tools.
• Extensive on-line documentation of all libraries.
