Accuracy of Computer Vision Hough Line Transform for Water Level Measurement

Abstract Floods are natural disasters that often occur in countries with high rainfall, such as Indonesia. due to sudden changes water level; therefore, the dam cannot withstand increase causing overflow into riverbank area. As a result of this issue, system was created can be used provide information about river levels. This relies on computer vision program camera monitor level through image processing. Image processing allows process surface detected at ditch’s edge. The edge detection is detector using Hough line transform, which generates indicate level. height by differs from actual surface. minimum and maximum error reading for both methods recorded experiment 0,8 % 16,67 %, respectively
