An optical remote meter reading system for a handheld device includes an imaging device, such as a CCD or CMOS device, coupled to a processor or DSP, to perform image analysis, optical character recognition (OCR), or both. An operator may point the handheld device at a meter, where the imaging device obtains a digital image of the meter. The processor or DSP then identifies an orientation of the meter and determines appropriate positions of pointers or dials, or numerical reading of digits from a digital readout. Various other components can be added to the handheld device, such as a light source (e.g., laser), and so forth.
