アナログ機器検針システム及び方法
Document Type and Number:
Japanese Patent JP7025962
Kind Code:
B2
Abstract:
To prevent human errors such as reading errors of visual measurement and errors in checking while reducing a labor of reading an analog device.SOLUTION: A device identification code 40 including device identification information and a position detection pattern 41 of an analog device 100 is formed in a vicinity of a scale board in advance, an image captured by the analog device is converted to 2-value image data by 2-value processing to fit the scale of the analog device 100 and the device identification code 40, and relative coordinates of each pixel of black data in a portion corresponding to the scale region of the 2-value image data are acquired. The relative coordinates of each pixel of the acquired black data are statistically processed to specify a position indicated by the indicator unit 101 within the scale region, and the measured value obtained by numerical representation of the analog value indicated by the instruction unit 101 is obtained.SELECTED DRAWING: Figure 1
