27.1	14	AIS is a video photo recognition sensor, the sensor can be used in electricity meters, gas meters, water meters, pressure gauges and other types of meters. Accurately identify the number of the current dial or upload the picture of the current dial for comparison, which can replace people to go to the door to read the meter, and is more accurate and energy-saving than the meter. The first thing to do is to fix the AIS sensor, the end direction needs to be aligned with the object that needs to be identified, you can check whether the object all appears in the lens range through the upper computer, and then calibrate, Chapter 2 will explain the calibration method of different tables.

Based on the format of the digital wheel dial, we can obtain each coordinate point of the current use dial. The (x,y) coordinate on the image is located at the bottom left corner.

54.2	262	2: Fill in the number of number wheel on their dial,eight;
50.2	263
54.2	264	3: Select the number of short Pointers (currently we don't use short Pointers, the "digit wheelu" option defaults to 0);
