Abstract
A digital measurement system and method for optical applications including a mobile client device having a digital camera and an audio port, and a laser measurement device having a laser. The laser measurement device connected to the mobile client device and electrically connected to the audio port of the mobile client device. The mobile client device is configured to activate the laser at the same time as the digital camera is activated, and capture an image of a patient. The mobile client device is configured to access a measurement module to calculate position of wear measurements based on a location of a laser mark in the captured image.
Claims22
A method for obtaining digital measurements, comprising:
- sending, by a mobile client device, an audio signal to activate a laser;
- capturing, by said mobile client device, an image of a patient wearing a selected frame at the same time as said laser is activated;
- and
- accessing, by said mobile client device, a measurement module configured to determine a position of wear measurement of said patient wearing said selected frame based on a location of a mark made by said laser in said captured image.
A method for obtaining digital measurements, comprising:
- activating at least one laser that is operatively coupled to a processor;
- capturing, by a camera that is operatively coupled to said at least one laser, an image of a patient wearing a selected frame and one or more laser marks that are generated on the wearer when said at least one laser is activated;
- and
- calculating, by a processor, at least one position of wear measurement of a lens relative to the physical features of the patient based on said captured image and said one or more laser marks in the image.
A method for obtaining digital measurements associated with a wearer wearing a selected eyeglass frame, comprising:
- providing a first and second laser that is operatively coupled to a handheld computing device having a camera;
- activating, by said handheld computing device, said first and second lasers so that a first and a second laser mark is projected onto the wearer;
- capturing, using said handheld computing device, an image of the wearer wearing the selected eyeglass frame and said first and second laser marks;
- and
- calculating, by said handheld computing device, at least one of a monocular pupil distance, a binocular pupil distance, a vertex distance, and a pantoscopic tilt at least partially based on a physical distance between said first and second lasers and a measured distance of said first and said second laser marks in said captured image.
