<p>An apparatus and method for determining and numerically displaying the volume of an item or any part of the item by passing a manually held sensor member freely movable over and along an item lying on a support surface. One or more sensors generate signal corresponding to the distance from the sensor member to points on the surface of the item. A movement detector arrangement generates signals corresponding to displacement of the sensor member along the item which may also include signals corresponding t the vertical movement of the sensor member above the support surface. These signals are processed in a signal processor to enable the calculation of cross sectional areas of each section of the item along the path of movement of the sensor member and to calculate the volume of a part or all of the item.</p> |
