SYSTEMS AND METHODS FOR THE MEASUREMENT OF SURFACES

摘要

The present invention discloses systems and methods for the measurement of surfaces. More particularly, the present invention discloses a portable, hand-held, non-contact surface measuring system comprising 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 present invention further discloses a method for the non-contact 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.
