A system and method for displaying a placement array of calibration locations, including capturing image data of a target object located in a workspace using an optical sensor communicatively coupled to a processor. Classification data is received from a database, based on the image data of on the target object within the view of the optical sensor. An origin point of the placement array of calibration locations based on the image data is determined. A plurality of calibration positions for the workspace in relation to the origin point is retrieved from the database, where the calibration locations are based on the classification data from the image data. The placement array of calibration locations is displayed on a display communicatively coupled to the processor in an augmented reality depiction of the workspace, where the placement array of calibration locations is oriented in the workspace based on the origin point. 1. A system for displaying a placement array of calibration locations , the system comprising:an optical sensor;a display communicatively coupled to the optical sensor;a processor;one or more memory modules communicatively coupled to the processor; and capture image data of a target object located in a workspace using the optical sensor communicatively coupled to the processor;', 'retrieve classification data from a database communicatively coupled to the processor, wherein the classification data is received from the image data;', 'determine an origin point of the placement array of calibration locations based on the image data;', 'retrieve a plurality of calibration positions of the placement array for the workspace in relation to the origin point from the database, wherein the calibration locations are based on the classification data; and', 'display, on the display communicatively coupled to the processor, the placement array of calibration locations in an augmented reality depiction of the workspace, wherein the placement array of calibration ...
