2/26/2004 - CSEM SA. has chosen WinDriver, the driver development tool from Jungo Software Technologies, Inc., to develop a USB driver for its optical time-of-flight range 3D camera. The new camera integrates groundbreaking technology developed by CSEM, and by using WinDriver, the driver development process was significantly shortened.
At the project's outset, CSEM had intended to develop a WDM driver for the Windows environment by making use of the DDK provided by Microsoft. With little experience in the development of drivers for Windows, it took CSEM some time to appreciate the complexity of the task and they began looking for alternative approaches.
"After searching for some time, we discovered how WinDriver could ease USB driver development," said Graham K. Lang, software developer at CSEM. "By using WinDriver, we were very quickly able to establish that the firmware already developed on the device side was performing correctly, and as a result, we were able to automatically generate a console program to communicate with the camera."
The next stage was straightforward - CSEM replaced the C functions and assembly language previously used for communication with the camera with function calls extracted from the source code generated by WinDriver.
"WinDriver's stability and ease of use allows our customers to quickly and easily develop high-performance, powerful and portable device drivers," said Ophir Herbst, General Manager of Jungo's Software Tools Division. "CSEM's success adds to the thousands of applications built with WinDriver all over the world, and demonstrates Jungo's commitment to building market-leading tools that solve our customers' driver development difficulties."
About TOF Cameras
Optical time-of-flight range cameras work with a modulated visible infrared light source. The emitted light pulses are reflected by the objects in a scene, traveling back to the camera, where their precise time of arrival is measured locally in each "smart" pixel of a custom image sensor. In contrast with conventional cameras, time-of-flight range cameras are able not only to determine the local brightness in a scene but also the complete distance map of the camera's environment. The distance resolution is limited by the amount of available reflected light and the timing precision of the camera's electronics. Thanks to the continuing advances of solid-state technology, the measurement precision today reaches the millimeter range.
