Troika - BrailleCAM
BrailleCAM is a hand-held, portable camera specifically designed to measure and view Braille dots with unrivalled precision and clarity. The camera utilises a PC link in order to show 3D images of a dot using colour representation, allowing the user to view dot form and inspect for surface cracking. The system also provides the tools necessary for highly detailed measurement and recording of dot values. BrailleCAM can measure male and female embossing tools as well as final output.
When measuring finished product, the auto-focus feature of the camera automatically finds the top surface. It then takes a series of images, each with a different focus depth, down to the ground level of the substrate. Software removes all un-sharp parts of each image and combines the levels into a rendered 3D grid model. This can be analysed via the PC and rotated in any direction.
