Abstract

A portable, hand-held, non-contact surface measuring system comprises an image capturing element, at least four projectable reference elements positioned parallel to one another at known locations around the image capturing element, a processing unit, and a user interface. The invention further discloses a method for the noncontact surface measurement comprising projecting at least four references onto a target surface, capturing an image of the targeted surface and the projected references with the image transferring device, transferring the image to a processing unit, processing the image using triangulation-based computer vision techniques to correct for skew and to obtain surface measurement data, transferring the data to the user interface, modifying the data with the user interface. The systems and methods for the measurement of surfaces can be applied to the measurement of biological surfaces, such as skin, wounds, lesions, and ulcers.

Claims

1. A portable, hand-held, non-contact self-contained surface measuring system capable of providing quantitative measurements of a target object on a target surface, the system comprising:

an image capturing element for capturing an image of at least a portion of the target object;

at least four projectable reference elements for defining at least one characteristic of at least a portion the target object, the projectable reference elements comprising a divergent configuration of lasers;

a processing unit; and

a user interface for displaying the captured image.
