提出了一种基于摄像机的能量可视化系统。为了进行监控，单个摄像机以固定的间隔捕捉煤气表图像。该系统采用边缘检测和连接分量标记来提取气体计数器中的数字区域。燃气消耗量是根据数字的形状特征来估计的。该系统利用数字字符的端点数和孔洞数，计算方向直方图和绝对差和（SAD）。该系统根据所获取的形状特征，通过模糊推理对数字进行识别。当系统无法识别某些事故的油耗时，从时间严肃数据中插入油耗。结果表明，我们的方法在33块中分别估计了32和29个数字，分别用于正面和倾斜测量。对于一天内的连续监测，系统成功地估计了动态气体消耗变化并将其可视化。
This paper proposes an energy visualization system by a camera. For monitoring, a single camera captures gas meter image at fixed intervals. The system applies edge detection and the connected-component labeling to extract numeral regions in counters of a gas mater. Gas consumption is estimated based on shape characteristics of numerals. The system uses number of endpoints and holes in numerical character, and it calculates a direction histogram and sum of absolute difference (SAD). The system recognizes the numeral by fuzzy inference from the acquired shape characteristic. When the system failed to recognize gas consumption by some accidents, the consumption is interpolated from time-serious data. In the result, our method estimated 32 and 29 numerals in 33 pieces for front and slant measurement respectively. For a continual monitoring in a day, the system successfully estimated dynamic gas consumption change and visualized them.
