Augmented reality for reflective particle tag alignment
| DWPI Title: Method for facilitating visual alignment of reflective particle tags, involves processing features by positioning three-dimensional model above digital representation of fiducial image placed on reflective particle tag |
| Abstract: A system and method for visual alignment of Reflective Particle Tags (RPT) includes creating a three-dimensional digital model of a reticle; processing a plurality of features based on the digital model; generating an Augmented Reality application; and deploying the Augmented Reality application on a camera platform. The augmented reality alignment system includes processors and memory devices having instructions that, when executed by the processors, cause the processors to perform operations of creating a three-dimensional digital model of a reticle; processing a plurality of features based on the digital model; generating an Augmented Reality application; and deploying the Augmented Reality application on a camera platform. A non-transitory, computer-readable medium comprising instructions that, cause the processors to create a model of a reticle; process features based on the model; generate an Augmented Reality application; and deploy the application on a camera. |
| Use: Method for facilitating visual alignment of reflective particle tags using augmented reality applications for a computer imaging unit e.g. smartphone and tablet computer. |
| Advantage: The method enables monitoring certain highly secured and restricted activities, e.g. transportation of nuclear fuel and its components across international borders, detecting undeclared activities related to national security and restricted activities, verifying integrity of equipment or items, reducing inspector burden, and maintaining a chain of custody between inspections. The method enables allowing accurate alignment of the RPT camera without physical contact by means of an augmented reality software application that allows the user to view a virtual bombsight comprised of two digital reticles. The method enables permitting precise alignment of all six-degrees of freedom so that photographic images may be repeatably taken by the RPT system. |
| Novelty: The method involves creating a three-dimensional (3D) digital model of a reticle. A set of features is processed based on the digital model. An augmented reality application is generated and deployed on a camera platform. The features are processed by positioning the 3D model above a digital representation of a fiducial image placed on a reflective particle tag (RPT). A misaligned image of the augmented reality application and an aligned image of the augmented reality application are viewed. A reference image representing fiducial is provided as a rectangular section of the RPT, where the fiducial bounded by a first line on an upper edge and a second line a lower edge, and the first line and the second line intersecting at a left edge of the fiducial and a right edge of the fiducial. |
