2D rectangular code symbol scanning device and 2D rectangular code symbol scanning method |
摘要 |
A two-dimensional rectangular code symbol scanning device inputs two-dimensional image data containing two-dimensional rectangular code symbol data and detects code data corresponding to the two-dimensional rectangular code symbol data. The device has a projective transformation calculator for correcting distortion of the two-dimensional rectangular code symbol data by performing projective transformation of the two-dimensional rectangular code symbol data.
