Water meter reading area detection method based on computer vision

The invention relates to a water meter reading area detection method based on computer vision, which belongs to the technical field of image processing and mode recognition, and comprises the following steps: carrying out image preprocessing operation on a complete water meter image, and carrying out angle correction on an inclined water meter image; segmenting a reading area in the complete water meter image by using a difference algorithm; dividing grids in the reading area to detect a target; recognizing the grid of each target number, comparing an obtained recognition frame with a real frame, adjusting a recognition model, and performing reading detection on the segmented reading area through the adjusted recognition model to obtain the water meter reading. 本发明涉及一种基于计算机视觉的水表读数区域检测方法，属于图像处理和模式识别技术领域，对完整的水表图像进行图像预处理操作，对倾斜的水表图像进行角度校正；利用差分算法算法将完整水表图像中的读数区域分割出来；在读数区域中划分网格，用来检测目标；对每个目标数字的网格进行识别，将得到的识别框与真实框进行对比，调整识别模型，通过调整后的识别模型对分割后的读数区域进行读数检测，得到水表读数。
