Tools for Changing Camera Parameters

46 Basler aviator Camera Link

4.1.2 The pylon Viewer

The Basler pylon Viewer is a standalone application that lets you view and change the camera’s

parameter settings via a GUI based interface. Using the pylon Viewer software is a very convenient

way to get your camera up and running quickly when you are doing your initial camera evaluation

or doing a camera design-in for a new project.

Note that with Camera Link cameras such as the aviator, the viewer can not display the images

captured by the camera. Most frame grabbers include software that will display the captured

images, so you can use the pylon viewer to view or change the camera’s parameters and the frame

grabber software to view the captured images.

The pylon Viewer is included in Basler’s pylon Driver Package. Currently, the aviator uses version

2.2 of the pylon package, which is a beta version of the package. To obtain the beta version free of

charge, contact Basler technical support (the contact numbers appear in the front pages of this

document).

For more information about using the viewer, see the Aviator Installation and Setup Guide

(AW000832xx000). You can download the guide from the Basler website:

4.2 The Basler Binary Protocol Library

Basler aviator cameras have blocks of mapped memory space known as registers. By reading

values from the registers, you can determine basic information about the camera and information

about the camera’s current settings. By writing values to the registers, you can control how the

camera’s features will operate.

If you use the Basler pylon software described in the previous section, the camera’s register

structure is hidden. With pylon, a series of function calls allows you to change camera parameter

settings without the need to know anything about the register that underlies each parameter.

If you desire, you can also change the camera parameter settings by directly accessing the

camera’s register structure. The Basler Binary Protocol Library (BBPL) provides functions that allow

you to read data from or write data to the camera’s registers. The BBPL is an extension of the

clALLSerial/clSerial API defined in Appendix B of the Camera Link Standard version 1.1 or higher.

The BBPL adds convenience functions to this API that allow you to read from and write to the

registers in Basler Camera Link cameras. The read and write requests are transmitted to the

camera via a serial link between the camera and the frame grabber; the serial link is part of the

standard Camera Link interface.

Sample code showing how to use the BBPL along with supporting documentation can be

downloaded from the Basler website: www.baslerweb.com/beitraege/beitrag_en_80604.html.

When using the BBPL to change parameter values, you will need to know the details of the

camera’s register structure. For details of the register structure, refer to the document called Aviator
