Identification encompasses a range of machine vision applications that involve reading printed characters and decoding 1D or 2D symbols on products. For traceability of production parts, verification of product lots or grading of print codes, DALSA’s Identification tools are designed for accurate results in the toughest of manufacturing environments.

2D matrix codes are widely used across many industries for part traceability and process control. The codes are popular for their small footprint, built-in error correction and large data capacity.
Teledyne DALSA 2D matrix algorithms provide decoding and grading of popular codes including ECC, QR, MicroQR, and PDF 417.
Date codes and lot codes printed on products provide critical expiration and traceability information. Products with unreadable codes become defective as consumers cannot verify product quality.
Character or symbol recognition is common in many manufacturing or production environments.
DALSA products include trainable Object Character Recognition (OCR) tools can handle the variation and diversity of most printing methods in use today.
OCR is based on pattern matching and so can be applied to a diverse range of verification applications outside of character reading. Often manufacturers will use OCR to build a library of parts that can later be identified and sorted.
1D barcodes are commonly used on products for traceability and sorting. Machine Vision verifies that the barcode matches the product that it is printed on.
DALSA's barcode product supports UPC, EAN, Code 39, Code 93, Code 128, Codabar, Interleaved 2 of 5, Pharmacode, BC412, Postnet, Planet, OneCode, RSS14 (Limited, Composite, Expanded).
