Hardware system for identifying grab-and-go transactions in a cashierless store

A system for identifying a transaction with one or more items available for purchase and stored in a pod, the pod comprising at least one shelf having a width from a left side to a right side and having a plurality of items storable thereon up to height A arranged along a depth D of the at least one shelf from a front of the at least one shelf towards a rear of the at least one shelf, the system comprising:

• at least one camera positioned within the pod to take photos of items on the at least one shelf, wherein the at least one camera is inclined with respect to the at least one shelf an inclination of an angle θ sufficient to allow the at least one camera to see items on or towards the rear of the at least one shelf without being completely occluded by items towards the front of the at least one shelf;
• a jig connected to the at least one camera, the jig comprising a mechanism for adjusting the angle of inclination the at least one camera;
• and
• a computing device communicatively connected to receive data representing one or more photos taken by the at least one camera, the computing device configured to recognize one or more physical interactions with a given item on the at least one shelf based on the data, identify a transaction associated with the one or more physical interactions, determine an adjusted angle θ of inclination to cover the depth D for items up to the height A while preventing occlusions, and control the mechanism to adjust the inclination of the at least one camera to the adjusted angle θ.
