Augmented Reality
"++ Reality"
Augmented reality technics superimpose, if possible in real-time, a virtual 2D or 3D object to the natural reality perception. The supplemental information enhance reliability of a difficult operation and accelerate a maintenance task.
Exploration of those technics began, for Bernard Peuchot, in 1994. Since then, those tools are constantly improved and optimized.
Spinal surgery
In LASMEA labs, with the strong interest and kind cooperation of Professor Alain Tanguy, Scoliosis surgery specialist, several technics are developed and tested improving operating field perception, precisely vertebrae position, as they are hidden behind muscular tissues at the beginning of the surgery.
Video below diplays all the development concepts, as well as the computer tools used then. (French speaking)
The following animation shows a vertebrae, a "physical mark" position, and the alpha-blending function, showing hidden parts of the vertebrae.
Underwater civil works
2013-14 : Augmented Reality tools definition, in order to help remote manipulations of an underwater excavator.
Civil works underwater machines are remotely operated from the surface. Embedded cameras are very often rendering really poor, when not unreadable images, caused by particules in suspension.
The full and precise 3D modelization of the excavator, then the real-time analysis of the camera images, allow the perfect superimposition in alpha-blending of the exact position of the tool in action.
