Abstract

The invention relates to a non-contact complex surface cone volume measurement system and method. The method includes the steps: firstly, providing three linear lasers to form a light sectioning plane and marking the contour of the section of a cone to be measured; secondly, providing a vertical lifter, moving the light sectioning plane relative to the cone to be measured; thirdly, providing a black and white camera for acquiring images and transmitting acquired image information to a computer for processing the image information to finally obtain the volume and a three-dimensional diagram of the cone to be measured. The measuring system and the method are simple and practicable, high in scanning speed and precision and low in requirement for the cone and environments and low in system cost.

Description

technical field [0001] The invention relates to a non-contact volume measurement system and method based on line-structured light scanning and image processing algorithms, which are applied to the non-contact measurement of the volume of cones on complex surfaces. Background technique [0002] Three-dimensional volume measurement technology plays an important role in many fields. In industrial production, scientific research and other departments, there are often complex surface cones like cones or pyramids that require fast and accurate volume measurement and reconstruction of three-dimensional images. Traditional methods of volume measurement include drainage method and three-coordinate measurement method. [0003] The most widely used method in traditional volume measurement is the drainage method, which uses the Archimedes principle, the buoyant force on an object immersed in a liquid is equal to the weight of the liquid displaced by the object, that is . In addition ...
