System and method of calibrating health of off-platter detector using integrated weigh platter

An imaging system comprising:

• an imaging assembly within a housing and configured to capture image data of an environment appearing in a field of view (FOV);
• a weigh platter configured to measure a weight of an object placed on the weigh platter and having a surface extending in a first transverse plane;
• a light emission assembly having one or more light sources each configured to emit a light beam along the surface of the weigh platter to impinge upon a respective reflector positioned distally from the light emission assembly;
• and
• a controller configured to (i) identify a zero weight condition for the weigh platter indicating absence of an object on the weigh platter and (ii) determine a health condition of each of the one or more light sources from a measured intensity of a reflection beam detected from the respective reflector,
• wherein the light emission assembly and the respective reflector form a portion of an off-platter detection assembly configured to detect an off-platter condition associated with the imaging system
• wherein the controller is further configured to determine the health condition of each light source by:
• measuring the intensity of the reflection beam detected from the respective reflector;
• comparing the intensity to a reference intensity predetermined for the light source;
• and
• in response to the comparison, determining the health condition of the light source,
• wherein the health condition of the light source is one of a healthy intensity light source condition, an acceptable intensity light source condition, and an unhealthy intensity light source condition,
• wherein the controller is configured to enter a recalibration mode in response to the controller determining the health condition of any of the one or more light sources is at the acceptable intensity light source condition or at the unhealthy intensity light source condition for longer than a degradation window of time, wherein the recalibration mode is for determining new intensity ranges corresponding to one or more of the healthy intensity light source condition, the acceptable intensity light source condition, and the unhealthy intensity light source condition, and
• wherein the recalibration mode is a manual recalibration mode indicated by a visual indication on the imaging system and configured to allow a user to manually set the new intensity ranges, or an automatic recalibration mode in which the controller is configured to set the new intensity ranges.
