Adaptive quick response code generation and display method

An infrastructure node operable for performing a vehicle-merchant transaction with a moving vehicle, comprising:

• a stationary structure;
• a sensor suite mounted to or collocated with the stationary structure;
• a display screen;
• and
• a server in communication with a merchant back office and having a processor and a non-transitory computer readable storage medium (“memory”) on which is recorded instructions, wherein an execution of the instructions by the processor causes the server to:
• dynamically generate a customized 2D bar code for scanning by the moving vehicle having a vehicle-mounted camera;
• detect parameters of the vehicle-mounted camera via the sensor suite as the moving vehicle approaches the stationary structure, the parameters including a distance and approach angle of the vehicle-mounted camera relative to the stationary structure;
• dynamically reshape a baseline 2D bar code in response to the parameters, via the processor, to thereby generate a customized 2D bar code having a modified shape, size, and/or data capacity relative to the baseline 2D bar code;
• transmit a display control signal to the display screen to cause the display screen to display the customized 2D bar code as the moving vehicle approaches the stationary structure, thereby enabling the vehicle-mounted camera to scan the customized 2D bar code during the vehicle-merchant transaction.

A method for dynamically generating a customized 2D bar code for scanning by a moving vehicle during a vehicle-merchant transaction, the method comprising:

• detecting parameters of a vehicle-mounted camera of the vehicle, via a sensor suite of an infrastructure node in communication with a merchant back office as the moving vehicle approaches the infrastructure node, the sensor suite including an infrastructure camera and one or more of a radar sensor, a lidar sensor, or an ultra-wide band (UWB) sensor mounted to the infrastructure node, wherein the parameters include a distance and approach angle of the vehicle-mounted camera relative to the infrastructure node;
• dynamically reshaping a baseline 2D bar code in response to the parameters, via a processor of the infrastructure node, to thereby generate a customized 2D bar code having a modified shape, size, and/or data capacity relative to the baseline 2D bar code, including:
• performing a three-dimensional (3D) to two-dimensional (2D) projection via the processor of the infrastructure node to cause a 2D plane of the customized 2D bar code when displayed via the display screen to be perpendicular to a focal axis of the vehicle-mounted camera;
• and
• calculating a required data capacity and resolution of the customized 2D bar code based on the relative position of the moving vehicle and the infrastructure node;
• transmitting a display control signal to a display screen of the infrastructure node;
• and
• displaying the customized 2D bar code on the display screen in response to the display control signal as the moving vehicle approaches the infrastructure node to enable the vehicle-mounted camera to scan the customized 2D bar code during the vehicle-merchant transaction.
