Virtual Instruments for Remote Experiments Visualization
نویسندگان
چکیده
Virtual instruments for remote experiments visualization implemented with LabVIEW graphical software tool are presented. First solution uses low cost web cameras with universal serial bus (USB) interface and NI-IMAQ for USB Cameras driver. Images from any USB imaging device with DirectShow support can be acquired with these free software driver. Images acquired within server application are lossy compressed with Joint Photographic Experts Group (JPEG) standard and sent over the Internet by using the National Instruments (NI) DataSocket technology. Client application displays received and decompressed image to the remote experiment user. Second solution uses digital cameras complying with IIDC specification and NI-IMAQ for IEEE 1394 Cameras driver. Compressed images are sent over the Internet by using LabVIEW shared variable.

متن کاملProcess Visualization with Levels of Detail
In this paper we demonstrate how we applied information visualization techniques to process monitoring. Virtual instruments are enhanced using history encoding – instruments are capable of displaying current value and the value from the near past. Multi-instruments are capable of displaying several data sources simultaneously. Levels of detail for virtual instruments are introduced where the sc...
