Inventory integrity system

A system, comprising:

• one or more processors communicatively to a point-of-sale (POS) system, the one or more processors configured to:
• detect a security exception for an item during a POS transaction, the security exception indicating a discrepancy between a weight or dimension of the item, as measured by a measurement apparatus, and first characteristic information stored in an item catalog;
• initiate a measurement procedure to resolve the security exception, the measurement procedure including a requirement for an individual to place the item on the measurement apparatus comprising at least one of a scale or a dimension analyzer;
• cause, as part of the measurement procedure, the measurement apparatus to obtain measured characteristic information for the item and causing one or more imaging devices positioned to monitor the measurement apparatus to capture image data representing performance of the measurement procedure by the individual, the image data including physical interaction by the individual with the item and the measurement apparatus;
• receive image data captured by one or more imaging devices monitoring the measurement apparatus;
• process the image data using a machine-learned model trained on labeled image data representing correct and incorrect measurement procedures, to extract one or more behavioral features indicative of compliance with an expected measurement protocol, the one or more behavioral features comprising at least one of a body orientation facing the measurement apparatus, a gesture placing the item onto the measurement apparatus, or a physical proximity of the individual to the measurement apparatus during the measurement procedure;
• generate, based on the one or more behavioral features, a confidence score representing a likelihood that the measurement procedure was performed correctly;
• determine, based on the confidence score, a procedural validity status for the measurement procedure, wherein the procedural validity status is valid when the confidence score satisfies a predefined threshold;
• and
• update the first characteristic information in the item catalog using the measured characteristic information obtained by the measurement apparatus during the measurement procedure, responsive to the procedural validity status being valid.

Non-transitory computer-readable media storing computer executable instructions that when executed by one or more processors cause the one or more processors to:

• detect a security exception for an item during a POS transaction, the security exception indicating a discrepancy between a weight or dimension of the item, as measured by a measurement apparatus, and first characteristic information stored in an item catalog;
• initiate a measurement procedure to resolve the security exception, the measurement procedure including a requirement for an individual to place the item on the measurement apparatus comprising at least one of a scale or a dimension analyzer;
• cause, as part of the measurement procedure, the measurement apparatus to obtain measured characteristic information for the item and causing one or more imaging devices positioned to monitor the measurement apparatus to capture image data representing performance of the measurement procedure by the individual, the image data including physical interaction by the individual with the item and the measurement apparatus;
• receive the image data captured by the one or more imaging devices monitoring the measurement apparatus;
• process the image data using a machine-learned model trained on labeled image data representing correct and incorrect measurement procedures, to extract one or more behavioral features indicative of compliance with an expected measurement protocol, the one or more behavioral features comprising at least one of a body orientation facing the measurement apparatus, a gesture placing the item onto the measurement apparatus, or a physical proximity of the individual to the measurement apparatus during the measurement procedure;
• generate, based on the one or more behavioral features, a confidence score representing a likelihood that the measurement procedure was performed correctly;
• determine, based on the confidence score, a procedural validity status for the measurement procedure, wherein the procedural validity status is valid when the confidence score satisfies a predefined threshold;
