Method of searching three-dimensional images [Express]



This invention relates to a method where finding three dimensional images is dependent on image data such as color, shape or size rather than on key words, as key words often inadequately define images and are prone to human error during the information input stage. In addition, errors in keywords result in misfiling of images.

Technology transfer

This technology is available for licensing. There is an opportunity for this invention to be developed for particular applications and for demonstration of the final product through a collaborative research project. The business opportunity may be referred to by its NRC ID: 10717

Market applications

Applications for this technology are extensive for all sectors, especially in those manufacturing sectors where locating specific components quickly is essential. The advantage of the invention is that keyword indexing of images is not necessary in order to search and retrieve images from a database of images.

How it works

A three-dimensional search model of an object is provided, determining substantially rotationally and translationally invariant values, using a processor, searching for models in a database associated with similar values with predetermined limits. Directional information is determined by orthogonal tensors of inertia in uniform mass distribution.


  • Applicable to objects of various shapes, sizes and weight
  • Significantly improves input information and search times
  • Reduction of human error
  • Allows to search for objects in any view
