Generating measurement data using image data

A computer system comprising:

• one or more computer processors;
• one or more computer readable storage media;
• and
• program instructions stored on the computer readable storage media for execution by at least one of the one or more processors, the program instructions comprising:
• program instructions to receive image data from a computing device;
• program instructions to identify an object included in the received image data;
• program instructions to determine a value that corresponds to the identified object included in the received image data;
• program instructions to determine whether the determined value corresponds to a defined action;
• the identified object including a machine-readable printed code, the identified object being part of a label, and the label including a fixed background pattern with a printed code;
• program instructions to overlay the label with a foreground transparent sliding mask with a shifted printed code, wherein the relative position of the sliding mask on the fixed pattern is governed by a lengthwise variation associated with measured data;
• and
• program instructions to position the fixed pattern of the printed code and the sliding mask resulting in a pattern/mask superposition exhibiting a single valid code for the value associated to the measured data.

An apparatus comprising:

• a background label, the background label depicting a first set of objects, wherein the background label is anchored to a fixed position;
• a foreground label overlaying the background label, the foreground label depicting a second set of objects, wherein the second set of objects matches the first set of objects, and wherein spacing between respective objects of the second set of objects is shifted relative to spacing between respective objects of the first set of objects, corresponding to defined measurement values associated with the foreground label and the background label;
• and
• a measurement device coupled to the foreground label, the measurement device being moveable in a first direction corresponding to observed measurement data, such that positioning of the measurement device results in a pattern/mask superposition exhibiting a single valid code for a value associated to the observed measured data.
