Identify Parts
In some vision inspection applications, you identify an object by reading barcodes or text printed on the object. This palette groups visual inspection steps whose purposes are to read 1D and 2D barcodes and read text on an object using optical character recognition (OCR).
| Step Name | Description |
|---|---|
| Read/Verify Text | Identifies an object based on text printed on the object. You can also use this step to perform optical character verification by comparing the characters of the string read in the image to reference characters. Refer to Read/verify Text Concepts for related information. |
| Classify Objects | Identifies an unknown sample by comparing its shape to classes of known samples. Refer to Classify Objects Concepts for related information. |
| Read 1D Barcode | Identifies an object based on the values encoded into its 1D barcode. You can compare the decoded data to a reference string or check whether the data contains a specific pattern. Refer to Read 1D Barcode Concepts for related information. |
| Read Data Matrix Code | Identifies an object based on the values encoded into its Data Matrix code. You can compare the decoded data to a reference string or check whether the data contains a specific pattern. Refer to Read Data Matrix Code Concepts for related information. |
| Read QR Code | Identifies an object based on the values encoded onto its QR or micro-QR code. You can compare the decoded data to a reference string or check whether the data contains a specific pattern. |
| Read PDF417 Code | Identifies an object based on the values encoded into its PDF417 code. You can compare the decoded data to a reference string or check whether the data contains a specific pattern. Refer to Read PDF417 Code Concepts for related information. |
