| description | The invention provides an automatic number recognition method and system for an LED display. The automatic number recognition method comprises the following steps: data transmitted into the LED display by a laser ranging module is transformed into a dot matrix image in a default specification; the narrowest row containing all data is selected as a recognition area from the dot matrix image according to the display position of the dot matrix image in the LED display, and each column of the recognition area is transformed into an integer; black pixel points in the recognition area are transformed into 1, and blank areas in the recognition area are transformed into 0; columns with all 0 in the recognition area are taken as partition columns, the recognition area is partitioned into single data, and the single data is in a type of number or decimal point; the recognition area is traversed according to default recognition rules, and the value of single data after partition is determined. According to the automatic |
