| description | The invention relates to a real-time recognition device and method for character wheels of a camera shooting type gas meter. The device comprises an image acquisition device, an image sensor and a mainboard, wherein the image acquisition device comprises a front shell, a rear shell, a front filter, a lens group, a voice coil motor and a fill-in light; a mainboard is arranged in the rear shell, thelens group is assembled on the voice coil motor, the object distance and the distance position of the lens group are adjusted by the voice coil motor under the control of a driving circuit, so that aphotographed object is imaged clearly, and a filter is arranged at the position, corresponding to the lens group, of the front shell. According to the product and the method, the position of the lastdigit of the character wheel of the gas meter can be automatically and rapidly recognized, the processes of manual alignment and sensitivity adjustment are reduced, and the device and the method haveextremely high environmenta |
