Automatic digital pressure gauge calibration is challenging due to various unconstrained conditions. Although existing CNN-RNN based methods have been almost perfect on scene text recognition. they fail to perform well on digital pressure gauge calibration that requires to be extremely computation-efficient and accurate.
