摘要
针对基于视频的数字式仪表数据采集中仪表类型的多样性和示值判读的复杂性,设计了一套完整的仪表示值自动判读算法,采用多种自适应算法进行了表盘图像预处理和刻度提取与分割,并采用协同模式识别算法进行表盘刻度的识别,较好地保证了算法的自动化程度和结果的准确性。实验表明,该算法自动化程度高,判读准确。具有较强的实用性。
Aiming at the diversity of apparatus kinds and the complexity of recognition in the digital apparatus data collection based on video,an auto-recognition arithme- tic is studied.Some auto-adaptive arithmetic are intro- duced to image pre-processing and extraction and seg- mentation of the scale value,the cognition network is applied to recognize the scale number.These arithmetic assure the automation and precise of this method.Ex- periment results indicate that this arithmetic has great practicability.
