摘要： A system and method for acquiring a machine-readable symbol are disclosed. Briefly described, one embodiment comprises receiving at least one scan line of a codeword row, determining a number of codewords of the codeword row, and collapsing an initialization symbol matrix into a partially-collapsed machine-readable symbol matrix based upon the determined number of codewords. Once the number of rows in the machine-readable symbol are determined, the partially collapsed machine-readable symbol matrix is further collapsed to the determined number of codeword rows.

摘要： Systems and methods of determining the volume and dimensions of a three-dimensional object using a dimensioning system are provided. The dimensioning system can include an image sensor, a non-transitory, machine-readable, storage, and a processor. The dimensioning system can select and fit a three-dimensional packaging wireframe model about each three-dimensional object located within a first point of view of the image sensor. Calibration is performed to calibrate between image sensors of the dimensioning system and those of the imaging system. Calibration may occur pre-run time, in a calibration mode or period. Calibration may occur during a routine. Calibration may be automatically triggered on detection of a coupling between the dimensioning and the imaging systems.

摘要： A system and method for identifying erasures in a 2D symbol is disclosed. One embodiment of a method for marking a codeword as an erasure in a Quick Response code (QR code) captured by a bar code reader includes, identifying the scrambling mask used for encoding the data in the QR code. A location of the codeword in the QR code corresponds with a portion of the scrambling mask. The codeword comprises multiple codeword bits and the portion of the scrambling mask comprises multiple mask bits. The method further includes, generating an unscrambled codeword by performing a logical operation between each of the multiple codeword bits and each of the multiple mask bits, generating a reference matrix by applying the scrambling mask to a uniform matrix, and/or comparing the unscrambled codeword with the reference matrix to determine whether the codeword is the erasure.
