Image Type Water Meter Character Recognition Based on Embedded DSP
This addresses the need for efficient and automated meter reading in utility management, but it is incremental as it applies existing projection methods to a specific domain.
The paper tackled the problem of automating water meter reading by developing a method that combines DSP processors with image processing algorithms to recognize characters from images captured at a fixed angle, achieving accurate recognition and replacing manual reading to improve efficiency.
In the paper, we combined DSP processor with image processing algorithm and studied the method of water meter character recognition. We collected water meter image through camera at a fixed angle, and the projection method is used to recognize those digital images. The experiment results show that the method can recognize the meter characters accurately and artificial meter reading is replaced by automatic digital recognition, which improves working efficiency.
