VISUAL POSITIONING SYSTEM AND METHOD BASED ON HIGH REFLECTIVE INFRARED IDENTIFICATION
A visual positioning system based on highly infrared-reflective identification, including a plurality of identification points (102), an infrared photographing device (101) and an image processing unit (103). The plurality of identification points (102) is passive identification points made of a highly infrared-reflective material and are arranged at equal intervals in a plane to be positioned; the infrared photographing device (101) is used for shooting a reflective image of the identification points (102); and the image processing unit (103) obtains a relative position and relative attitude variation by acquiring and analyzing information about an image shot by an infrared camera (101a). Also provided is a visual positioning method based on highly infrared-reflective identification. The visual positioning system and method have the advantages of simple structure, no need of power supply, low costs, no delay and high positioning precision.

METHOD AND APPARATUS FOR INCREASING MEASUREMENT ACCURACY USING A CAMERA ENABLED PORTABLE COMPUTING DEVICE
A system, method, and apparatus for measuring a workspace is provided. The method includes capturing a workspace that is virtually represented on a user interface display of a computing apparatus that image-captured the workspace. The user inputs, via the user interface, a value of a known measurement of a length represented in the virtual workspace. Through the user interface, along the virtual workspace, the user identifies virtual end boundary points of the length associated with the known measurement. The user then defines a defined space within the virtual workspace by placing additional virtual boundary points. The system calibrates from the inputted value and the virtual end boundary points of the known measurement all the remaining measurements of the surface area, which can be used to render a map display and calculate surface area, volume, or any other geometric aspects of the defined space.
