Abstract
Embodiments of a system and method for sorting and delivering articles in a processing facility based on image data are described. Image processing results such as rotation notation information may be included in or with an image to facilitate downstream processing such as when the routing information cannot be extracted from the image using an unattended system and the image is passed to an attended image processing system. The rotation notation information may be used to dynamically adjust the image before presenting the image via the attended image processing system.
Claims14
A computer-implemented method comprising:
- under control of one or more processors,
- receiving an image of an item from item processing equipment, the item processing equipment comprising one or more mechanical devices configured to physically move the item in a distribution network;
- receiving a first optical character recognition (OCR) result for the received image, the first OCR result comprising text identified in the image, the first OCR result further comprising a confidence value indicating a degree of certainty of the text identified in the image;
- determining that the first OCR result is sufficient to make a further processing decision based at least in part on the confidence value;
- generating a second processing equipment control message based at least in part on the first OCR result;
- and
- transmitting the second processing equipment control message to the one or more mechanical devices of the item processing equipment, wherein the second processing equipment control message comprises one or more configuration parameters configured to adjust the one or more mechanical devices such that at least one of the one or more mechanical devices is adjusted to route the item to an intended location in the distribution network based on the identified text obtained by the first OCR result.
A computer-implemented system comprising:
- a memory storing instructions;
- and
- one or more image processing servers configured to execute the instructions to:
- receive an image of an item from item processing equipment, the item processing equipment comprising one or more mechanical devices configured to physically move the item in a distribution network;
- receive a first optical character recognition (OCR) result for the received image, the first OCR result comprising text identified in the image, the first OCR result further comprising a confidence value indicating a degree of certainty of the text identified in the image;
- determine that the first OCR result is sufficient to make a further processing decision based at least in part on the confidence value;
- generate a second processing equipment control message based at least in part on the first OCR result;
- and
- transmit the second processing equipment control message to the one or more mechanical devices of the item processing equipment, wherein the second processing equipment control message comprises one or more configuration parameters configured to adjust the one or more mechanical devices such that at least one of the one or more mechanical devices is adjusted to route the item to an intended location in the distribution network based on the identified text obtained by the first OCR result.
