Orientation-based hashing for fast item orientation sensing

A system configured to adjust item orientation, the system comprising:

• a memory configured to store an item-feature hash table, wherein the item-feature hash table is configured to relate feature-hash values to item orientation parameters;
• and
• a processor operatively coupled to the memory and configured to perform or control performance of:
• collect multiple orientations associated with an item;
• determine feature-hash value based on the collected multiple orientations associated with the item, wherein the multiple orientations include a vertical position of the item, a horizontal position of the item, or a tilted position of the item, with respect to a coordinate axis;
• determine item orientation parameters associated with the feature-hash values from the item-feature hash table;
• and
• adjust, based on the determined item orientation parameters, at least one of the multiple orientations associated with the item.

A system configured to determine item orientation, the system comprising:

• a memory configured to store an item-feature hash table, wherein the item-feature hash table is configured to relate feature-hash values to item orientation parameters;
• and
• a processor operatively coupled to the memory and configured to perform or control performance of:
• determine a feature-hash value based on at least one feature associated with an item;
• determine, from the item-feature hash table, an item orientation parameter associated with the feature-hash value, wherein the item orientation parameters, which are similar, are grouped into nearby hash buckets within the item-feature hash table;
• and
• determine an actuation signal based on the item orientation parameter associated with the feature-hash value.

A system configured to determine an item orientation, the system comprising:

• a memory configured to store an item-feature hash table, wherein the item-feature hash table is configured to relate feature-hash values to item orientation parameters;
• an imager device operatively coupled to the memory and configured to determine at least one feature associated with an orientation of an item;
• and
• a processor operatively coupled to the memory and the imager device, and configured to perform or control performance of:
• determine a feature-hash value based on the at least one feature associated with the orientation of the item;
• determine an orientation signal by use of the feature-hash value as a key for the item-feature hash table;
• provide the orientation signal to an actuator;
• and
• adjust, via the actuator and based on the determined orientation signal, the orientation of the item.

A method to adjust item orientation, the method comprising:

• determining, by an imager device, at least one feature associated with an orientation of an item;
• determining, by an orientation controller operatively coupled to the imager device, a hash value based on the at least one feature;
• determining, by the orientation controller, an orientation signal by use of the hash value as a key for an item-feature hash table, wherein the item-feature hash table is configured to relate feature-hash values to item orientation parameters, and wherein the item-feature hash table is generated based on locality-sensitive hashing and/or parameter sketching;
• providing, by the orientation controller, the orientation signal to an actuator;
• and
• adjusting, by the actuator based on the orientation signal, the orientation of the item, wherein the adjustment of the orientation of the item facilitates the item being fitted into an output chute of a system that is configured for at least one of a distribution, packaging, and inspection of the item.
