Aiming at the problems of print and recognition technology of three-dimensional barcode,color space options suitable for the needs of actual product package and print are studied.Based on three-dimensional barcode image,a fixed color adaptive threshold Canny edge detection algorithm is presented.Data Matrix three-dimensional barcode is used as an example to divide the barcode image from the collected images through image pretreatment and location.Then,recognition algorithm is studied based on the fixed color three-dimensional barcode image segment.Finally,the feasibility of the method is validated by practical application.
