LEITURA AUTOMÁTICA DE INSTRUMENTOS ANALÓGICOS DE MEDIÇÃO

Rynaldo Z. H. AlmeidaFlavius P. R. Martins

A computer vision system for automatic reading of analogical measurement devices isproposed. Such a system can be especially useful to the automation of calibration processes or othertests that require repetitive readings. The approach is based on the comparison between the slopes ofthe pointer and the display scale marks. Several automatic reading tests were carried out and theuncertainties obtained were equivalent to the human ones. The process success rate was around 99%.
