<p>An optical recognition method comprises: performing optical scanning on a first optical scanning region; when a first identifier is scanned, performing optical scanning on a second optical scanning region in a preset range behind the first identifier; or when a second identifier is scanned, stopping optical scanning on the second optical scanning region, the first identifier is disposed before the second optical scanning region, and the second identifier is disposed behind the second optical scanning region. By using the recognition method, fast recognition can be performed, and load of a scanning device can be reduced.</p> |
