The Water Level Automatic Measurement Technology Based on Image Processing

Abstract:

Design a real-time hydrological monitoring system. Using the ARM processor and video server combination of methods, realize the characteristic features of the next place machine extraction, and then through the GPRS connect PC . Also have the power supply, low power consumption, anti-interference characteristics. The system use Wince programming, to obtain the binary image, using morphological algorithm to remove useless characteristic features, then carries on the edge refinement, use the hough transform to extract the straight line equation of water level and the bank line to compute, can get out the distance between the two in the image, according to the actual coordinate can get the actual distance. The experimental results show that the system has a real time and efficiency, effectiveness, and other characteristics, get a good recognition effect.
