Sistema de localización y asistencia a la navegación para invidentes mediante visión artificial


Oferta Tecnológica
Un grupo de investigación español está desarrollando un sistema de navegación y asistencia a la navegación para guiar a invidentes mediante el uso de información acústica en entornos estructurados cerrados y al aire libre. El grupo de investigación utiliza la fusión entre un sensor GPS (sistema de posicionamiento global) y visión artificial. Se trata del primer sistema en todo el mundo que utiliza mapas visuales obtenidos de una cámara en estéreo para asistencia a la navegación de invidentes utilizando información visual. Otras aplicaciones comerciales incluyen realidad aumentada, videojuegos o robots humanoides, entre otras. Se buscan empresas especializadas en diseñar sistemas de asistencia a la movilidad para invidentes con el fin de establecer acuerdos de licencia o comercialización con asistencia técnica.


Location system and navigation assistance for blind people using artificial vision.
A Spanish research group is developing an assistance navigation system for blind people to guide them, using acoustic information, in structured indoor environments and outdoor environments as well. The group use the merger between a GPS (Global Positioning System) sensor and artificial vision. They are interested in reaching license, or commercial agreements with technical assistance with companies dedicated to the designing of mobility assistance systems for blind people.

Navigation assistance to blind people is nowadays not sufficiently robust and simple and it cannot obtain an accurate location of the user in a known or unknown environment, both indoors and outdoors location. Also actual systems do not use visual information. The main objective of this navigational system for blind people tis to solve this problem.

In this way the system will indicate the path that a person must follow to get to a destination, using acoustic information obtained by a voice synthesizer, similar to how the current GPS navigators do it. To this end, a method of locating and learning will be used, inspired in how human beings use visual capacity.

The location and environment mapping are two dependent processes that are calculated while the user navigates through it. The techniques are called SLAM (Simultaneous Localization and Mapping) and in recent years they have extended their application in the field of robotics and other emerging fields such as locating for blind people or surgery minimally invasive.

As a result of the great advances in research on object recognition using artificial vision, computers are able to recognize places such as monuments, or identify different objects in an image, such as faces or people, just by analyzing a single image. More and more, computers can develop similar tasks to the human vision.

The system has the following main features:

- System based on artificial vision: A stereo vision system will be used for mapping the environment. However, once it has obtained a 3D map of the environment, the location can be performed using a single camera in black and white, with the associated reduction of the costs. In addition to these cameras, the user carries in a backpack a small processor and the cables for the connection. The information of the current location or the route to follow is sent to the user through headphones. It is planned to merge the vision system with a GPS sensor that can be use in outdoor environments.

- Mapping phase: During the phase of mapping the blind user, with or without any expert, or only the expert himself, will make a particular route, mapping certain parts of a city or a building. Once an optimized 3D map is obtained, this map can be used by users to locate themselves on it.

- Location phase: During the location phase, the user, using only one camera (which might even be any mobile phone camera) can walk through an environment, while his/her current location on the map is provided on real time.

- Simultaneous localization and mapped phase: It can happen that in certain circumstances users walk through areas not previously registered on the map. In such cases, a relative location can be provide to the user and add this new information extending the mapping environment.

- Navigation phase: In this phase, you can plan some routes to be taken by the user, during which the system reports the actions to take.

- Perception phase: During the phase of perception, some artificial vision applications can be performed, such as detecting obstacles like pedestrians, trees, walls ... or other applications that may be of interest to the community of blind users.

The group is looking to reach license agreement, or commercial agreements with technical assistance. They are looking for companies dedicated to the designing of mobility assistance systems for blind people.
Advantages and Innovations:

It is the first system worldwide that presents the use of visual maps obtained by a stereo camera for navigation assistance to blind people, using visual information


The system has also commercial uses in a variety of fields such as: assistance to blind navigation, augmented reality, video games, humanoid robots, etc

Stage of Development:
Under development/lab tested
Patents granted
CommeR Statunts Regarding IPR Status:
National patent.

Partner sought

Type and Role of Partner Sought:
The group is looking for license agreements, but it is also open to achieve commercial agreements with companies dedicated to the designing of systems to assist navigation of blind users, augmented reality, video games or humanoid robots.
