Abstract
Systems, devices, and methods for automatic data collection. An automatic data collection system includes an image capture subsystem and a processor subsystem. The automatic data collection system is operable to decode machine-readable symbols in a machine-readable symbol reading mode, and to automatically switch from a machine-readable symbol reading mode to an optical character recognition mode in response to information encoded in a machine-readable symbol. In some embodiments, the automatic data collection system is further operable to perform optical character recognition on human-readable symbols in a human-readable symbol reading mode.
Claims23
A method of operating an automatic data collection device, the method comprising:
- reading a machine-readable symbol;
- determining a location of a first number of human-readable symbols from information encoded in the machine-readable symbol;
- determining a location of a second number of human-readable symbols from information encoded in the machine-readable symbol, the second number of human-readable symbols spaced from the first number of human-readable symbols;
- reading the first number of human-readable symbols;
- reading the second number of human-readable symbols;
- and
- verifying information contained in the first number of human-readable symbols based at least in part on information contained in the second number of human-readable symbols.
An automatic data collection system, comprising:
- an image subsystem operable to capture images;
- and
- a processor subsystem configured to decode a machine-readable symbol acquired by the image subsystem, determine a first location of a first number of human-readable symbols from information encoded in the machine-readable symbol, determine a second location of a second number of human-readable symbols from information encoded in the machine-readable symbol, the second number of human-readable symbols spaced from the first number of human-readable symbols, read the first number of human-readable symbols at the first location, read the second number of human-readable symbols at the second location, and verify information read from the first number of human-readable symbols based at least in part on information read from the second number of human-readable symbols.
A method of automatic data collection from objects bearing a machine-readable symbol, a first number of human-readable symbols, and a second number of human-readable symbols spaced from the first number of human-readable symbols, the method comprising:
- automatically reading the first number of human-readable symbols;
- automatically reading the second number of human-readable symbols;
- and
- verifying information read from the first number of human-readable symbols based at least in part on information read from the second number of human-readable symbols;
- automatically reading the machine-readable symbol before automatically reading the first and the second number of human-readable symbols;
- determining a location of the first number of human-readable symbols from information encoded in the machine-readable symbol;
- and
- determining a location of the second number of human-readable symbols from information encoded in the machine-readable symbol.
An automatic data collection system, comprising:
- an image capture subsystem operable to capture images;
- and
- a processor subsystem configured to read a first number of human-readable symbols, read a second number of human-readable symbols, and verify information read from the first number of human-readable symbols based at least in part on information read from the second number of human-readable symbols;
- wherein the processor subsystem is further configured to read a machine-readable symbol before reading the first and the second number of human-readable symbols, and determine a location of the first number of human-readable symbols from information encoded in the machine-readable symbols;
- and
- wherein the processor subsystem is further configured to determine a location of the second number of human-readable symbols from information encoded in the machine-readable symbol.
