Halytech as released a special microSpider Industrial based solution that provides all the standard microSpider logging and reporting capabilities PLUS video capture and transmission for server-based analysis of river flows and volumes.
The microSpider manages all the video camera power, operation and storage functions plus the transmission of captured video to a central server. Transmitted footage is then centrally processed to calculate flow rates and volumes in channels and rivers.
Video is captured and transmitted controlled by the hydroSpider based on; a time schedule and/or on exception events such as high rainfall, changes in level or other events based on any measured parameter.
Power consumption is kept to a minimum as the camera is only powered as required. IR camera capabilities even allow for operation of the solution at night time.
The back-end software, not provided by Halytech, uses novel video analysis techniques which can calculate flow rates using water surface image analysis and calculate river discharge. KU-STIV (Kobe University Space-Time Image Velocimetry) is one example of image analysis software that could be used
