1.) Is it necessary to apply always metric calibration?
No. To implement metric calibration is necessary only if we intend to gather metric measurments or register point clouds with Match 3D. If the 3D model is only going to be used in a comparative approach, metric calibration is not necessary.

2.) How do I get SAL3D?
A fully featured version of SAL3D can be downloaded from our web page, after registering in the downloads section. This version includes all the documentation in .pdf and .html when the installation has been completed. You can work with, or implement in your system this libraries during 90 days since the libraries are used for the first time.. To continue working with SAL3D a dongle has to be purchased directly from us or from one of our distributors.

3.) What is the best way to get started with SAL3D?
You can start by registering in the downloads area, and get the latest fully featured release of SAL3D. You have 90 days for evaluating all the tools, implement them in your inspection system, etc. Besides, you can go download SAL3D Quick Start Guide where a 3D shape analysis library example has been included.
Along with the tool libraries, SAL3D comes with some Range Maps, source code of example programs, and precompiled binaries of those programs.

4.) How do I get SAL3D documentation?
Documentation about SAL3D is available from the program menu when installed. A Quick Start Guide, and a complete SAL3D guide are available from the Support/Documentation section.

5.) Can I acquire only certain tools from SAL3D?
Yes, you might only need certain features, so you can buy the tools that are more convenient for you. SAL3D has been conceived as a flexible software, so more tools can be added afterwards if you require so.

6.) Does the license expires?
The license never expires when you have purchased a dongle. The package available online expires 30 days the libraries have been used for first time. The user can check the validity of the licences found using a web browser, looking at the URL: http://localhost:1947/

7.) What happens when the demo expires?
You will not be able to use SAL3D tools until you acquire a dongle key.

8.) What operating systems are supported by SAL3D?
Windows 2000 SP4, Windows XP SP2, or Windows Vista 32-bit
Versions for other Operating Systems like GNU/Linux are also available. Please forward your queries to

9.) If I use SAL3D in different inspection stages, Do I have to purchase as many licenses?
You need a license per each machine (PC) where SAL3D is running. This concedes no restrictions in the number of cameras to be combined in an inspection stage, or even the number of inspection stages along the production line (bewaring of the speed and simultaneity constrains)

10.) Do I need a 3D camera for running SAL3D in my application?
SAL3D is a library that resides in the PC and acquires the data from the frame grabber(see frame grabbers). Therefore, SAL3D is suitable for being used with any camera. Because SAL3D is a library oriented to 3D point cloud applications, it is desirable to use a 3D camera. In case a 3D camera is not available, it can be replaced by a 2D camera + software peak detector tool, for laser triangulation applications.

11.) I am using a 3D camera, does it means I get 3D information from the capture?
Most of the 3D cameras do not directly provide information in metric units. In order to get calibrated 3D clouds of points for gathering metric measurements, the system must be calibrated first in order to get metric information from the Range Map provided by the camera. For example with the Metric Calibration Tool (see info )
