Image Acquisition and Processing at the Swiss Light Source
نویسنده
چکیده
The integration of all devices under one coherent control system based on EPICS is an important consideration at the SLS. On the other hand, image acquisition and processing is a daily activity for devices in the accelerators, beamlines and experimental stations. Currently, we have developed two approaches, under EPICS, for image acquisition and processing. One is based on an analogue camera with a VME frame grabber connection, and the other is a Firewire (IEEE1394) CCD camera interfaced to a Linux PC. Both approaches allow to control the relevant camera parameters and to perform basic image processing. We report here on our approaches, applications, conclusions and future work.

Data acquisition software is an essential component of modern macromolecular crystallography (MX) beamlines, enabling efficient use of beam time at synchrotron facilities. Developed at the Paul Scherrer Institute, the DA+ data acquisition software is implemented at all three Swiss Light Source (SLS) MX beamlines. DA+ consists of distributed services and components written in Python and Java, wh...
متن کاملFeasibility of detecting and localizing radioactive source using image processing and computational geometry algorithms
We consider the problem of finding the localization of radioactive source by using data from a digital camera. In other words, the camera could help us to detect the direction of radioactive rays radiation. Therefore, the outcome could be used to command a robot to move toward the true direction to achieve the source. The process of camera data is performed by using image processing and computa...

The current methods of turfgrass evaluations are often based on human-based assessment methods. However, eliminating subjective errors from such evaluations is often impossible. This research compared the accuracy of human-based and digital image processing-based methods for quality assessment of turfgrasses. Four turfgrass plots were evaluated using the two mentioned methods. In the human-base...
