SCANNING OBSTACLE SENSOR FOR THE VISUALLY IMPAIRED
Various arrangements for avoiding obstacles for a visually-impaired pedestrian are presented. An m by n matrix of distance measurements may be created using a scanning time of flight (ToF) sensor component for various different directions. The m by n matrix of distance measurements and the m by n di...

| description | Various arrangements for avoiding obstacles for a visually-impaired pedestrian are presented. An m by n matrix of distance measurements may be created using a scanning time of flight (ToF) sensor component for various different directions. The m by n matrix of distance measurements and the m by n direction matrix may be analyzed to identify a first obstacle having a vertical height that differs by at least a predefined threshold measurement from a neighboring second region. Based on identifying the first obstacle, an indication of the first obstacle and an indication of the distance to the first obstacle determined using the m by n matrix of distance indications may be output.
L'invention concerne divers agencements permettant à un piéton malvoyant d'éviter des obstacles. Une matrice m par n de mesures de distance peut être créée à l'aide d'une composante de capteur de temps de vol (ToF) à balayage pour diverses directions différentes. La matrice m par n de mesures de distance et la matrice de direction m par n peuvent être analysées pour identifier un premier obstacle ayant une hauteur verticale qui diffère, selon au moins une mesure seuil prédéfinie, par rapport à une seconde région voisine. En fonction de l'identification du premier obstacle, une indication du premier obstacle et une indication de la distance par rapport au premier obstacle déterminée à l'aide de la matrice m par n d'indications de distance peuvent être délivrées. |
