Method for tuning an imaging assembly via a focus triggering marker

A method for setting a focus parameter of a variable focus imaging assembly, the method comprising:

• capturing, by an imaging sensor of the variable focus assembly, a first image of a focus triggering marker positioned at a first distance within a field of view of the imaging sensor;
• identifying, by a processor of the variable focusing imaging assembly, the focus triggering marker in the first image;
• responsive to identifying the focus triggering marker in the first image, entering the variable focusing imaging assembly into a configuration mode;
• monitoring, by the imaging assembly and after entering the configuration mode, the field of view to identify a removal of the focus triggering marker from the field of view of the imaging sensor;
• determining, by a processor, that the focus triggering marker has been removed from the field of view of the imaging sensor;
• executing, subsequent to removal of the focus triggering marker, a focusing operation to focus the imaging assembly including determining a focus value based on one or more images captured in the configuration mode and after the focus triggering marker has been removed from the field of view of the imaging sensor;
• setting, via a controller configured to control a focal distance of a tunable optical element of the imaging assembly, the focal distance of the tunable optical element according to the focus value;
• and
• capturing, by the imaging sensor, one or more images with the focal distance of the tunable optical element set to the focus value.

A focus parameter tuning variable focus imaging system comprising:

• a tunable optical element;
• a controller in communication with the tunable optical element, the controller configured to control a focal distance of the tunable optical element;
• an imaging sensor configured to capture images of a field of view of the imaging sensor;
• and
• a processor and computer-readable media storage having machine readable instructions stored thereon that, when the machine readable instructions are executed, cause the imaging system to:
• capture, by the imaging sensor, a first image of a focus triggering marker positioned at a first distance within a field of view of the imaging sensor;
• identify, by the processor, the focus triggering marker in the first image;
• enter, upon identification of the focus triggering element, the variable focusing imaging assembly into a configuration mode and providing a time delay;
• execute, subsequent to the passing of the time delay, a focusing operation to focus the imaging assembly including determining a focus value based on one or more images captured in the configuration mode and after the time delay;
• set, via the controller, the focal distance of the tunable optical element according to the focus value;
• and
• capture, by the imaging sensor, one or more images with the focal distance of the tunable optical element set to the focus value.
