Measurement apparatus
First Claim
1. Measurement apparatus for measuring at least one parameter of an object or area, the measurement apparatus comprising one or more imaging and display devices for creating a three-dimensional map and displaying an image of said object or area, mapping apparatus for mapping a virtual shape onto said image and substantially matching said shape to said object or area, the measurement apparatus being adapted to determine from said image at least one parameter of said object or area, said parameter comprising at least one of a length, surface area or volume of said object or area.

Abstract
Measurement apparatus for measuring at least one of a length, surface area or volume of an object (or portion thereof) or area (22) (or portion thereof). The apparatus includes means for creating a three-dimensional map of an object or area to be measured and a touch-sensitive screen (16) for displaying the mapped image of the object or area. The user can select the area (22) of interest by drawing around it on the screen to create an outline of its shape and the apparatus then creates a virtual shape (20) which matches the outline and maps it onto the image. The user can alter the size, angle, pitch, etc. of the virtual shape (20) until it matches the area (22) exactly and the apparatus then determines the length, surface area and/or volume of the area (22), as required.

- 7. A method of measuring an object or area, the method comprising the steps of creating a three-dimensional map and displaying an image of an object or area to be measured, mapping a virtual shape onto said image, substantially matching said virtual shape to said object or area being measured, and determining at least one of a length, surface area or volume of said object or area.
- 11. Measurement apparatus comprising one or more image capture devices for capturing at least one image of said object or area, display apparatus for displaying in a two-dimensional image space an image of said object or area, the apparatus being arranged to create a three-dimensional map of said object or area from at least one image captured by said one or more image capture devices, the measurement apparatus further comprising shape matching apparatus for matching a shape to said image of said object or area as displayed in said two-dimensional image space, and calculation apparatus for determining from said displayed image at least one of a length, surface-area or volume of said object or area.
