Machine vision calibration system with marker

A system comprising:

• a marker comprising:
• a substrate;
• an array of graphical elements arranged in rows and columns on the substrate, wherein a number of columns is greater than a number of rows, and wherein color and placement in the array of the graphical elements encodes marker data;
• a first border with a first color on the substrate, the first border extending uninterrupted around a perimeter of the array;
• a visible light layer arranged over the array, wherein the visible light layer is transmissive of at least 50% of incident infrared light and less than 10% of incident visible light;
• and
• wherein the graphical elements interact with at least a portion of the incident infrared light.

A system comprising:

• a marker comprising:
• an array of graphical elements using color and placement, the color and the placement each being used for separately encoding marker data, the array of graphical elements being arranged in rows and columns on a substrate, wherein a number of columns is greater than a number of rows;
• a source graphic image blended with at least a portion of the graphical elements in the array;
• and
• a first border extending uninterrupted around a perimeter of the array of graphical elements.

A system comprising:

• a marker on a shelf, the marker comprising a two-dimensional matrix code;
• a camera within a facility;
• a memory, storing computer-executable instructions;
• and
• a hardware processor in communication with the camera and the memory, wherein the hardware processor is configured to execute the computer-executable instructions to:
• generate calibration data for the camera, wherein the calibration data is generated using image data obtained by the camera which depicts the marker and marker data encoded in the two-dimensional matrix code;
• and
• identify an object in the facility using the camera, after calibration of the camera has been performed.
