Title
(DE) VERFAHREN ZUR BESTIMMUNG DER AUSRICHTUNG EINES AUSRICHTUNGSINDIKATORS
(EN) METHOD FOR DETERMINING THE ORIENTATION OF AN ORIENTATION INDICATOR
(FR) PROCEDE POUR DETERMINER L'ORIENTATION D'UN INDICATEUR D'ORIENTATION
Abstract
(DE) Zum Zweck der Ermittlung der Ausrichtung eines Ausrichtungsindikators werden von einem Abstandsmessensor und einem Bildsensor in einem Messgerät (1) ein Abstand von wenigstens einem und ein Bild von wenigstens drei reflektiven Bereichen auf dem Ausrichtungsindikator erfasst. Die Abstandsmessung und Bilderfassung erfolgt vermittels einer gerichteten Emission eines kollimierten ersten Strahlenbündels (2) und eines divergenten zweiten Strahlenbündels (3) mit unterschiedlicher Wellenlänge und/oder Polarisation in Richtung des Ausrichtungsindikators und einer gleichzeitigen Erfassung des reflektierten und/oder gestreuten ersten und zweiten Strahlenbündels (2',3'). Die reflektiven Bereiche auf dem Ausrichtungsindikator sind so ausgebildet und angeordnet, dass sie an einem Zielpunkt positionierbar sind, sowie in detektierbarer geometrischer Beziehung zueinander stehen und vermittels der Bilderfassung gleichzeitig aufgelöst werden können. Anhand der Ausrichtungsbestimmung können unter anderem Abstände zu - auch nicht direkt einsehbaren - Zielpunkten genau bestimmt werden.
(EN) According to the invention, a separation from at least one and an image of at least three reflective regions on the orientation indicator are recorded by a separation measurement sensor and an image sensor in a measuring device (1), for the purpose of determining the orientation of an orientation indicator. The separation measurement and image recording are achieved by means of a directed emission of a collimated first beam (2) and a divergent second beam (3) with differing wavelengths and/or polarisation in the direction of the orientation indicator and a simultaneous recording of the reflected and/or scattered first and second beams (2',3'). The reflective regions on the orientation indicator are embodied and arranged such as to be positioned at a target point with a detectable geometric relationship to each other and to be simultaneously resolved by the image recorder. By means of the orientation determination, amongst other things, separations from target points, even not directly visible, can be precisely determined.
(FR) Selon l'invention, une distance par rapport à au moins une zone de réflexion ainsi qu'une image d'au moins trois zones de réflexion sont détectées sur un indicateur d'orientation par un capteur de mesure de distance et un capteur d'images dans un appareil de mesure (1) afin de déterminer l'orientation de l'indicateur d'orientation. La mesure de distance et la détection d'images s'effectuent par émission orientée d'un premier faisceau de rayons (2) collimaté et d'un deuxième faisceau de rayons (3) divergent présentant une longueur d'onde et/ou une polarisation différentes en direction de l'indicateur d'orientation et par détection simultanée du premier et du deuxième faisceau de rayons (2', 3) réfléchi et/ou dispersé. Les zones de réflexion sur l'indicateur d'orientation sont formées et disposées de façon à pouvoir être positionnées en un point cible, à se trouver dans une relation géométrique détectable et à pouvoir être simultanément restituées au moyen de la détection d'images. Il est possible entre autres de déterminer avec précision des distances par rapport à des points cible, même si ceux-ci ne sont pas directement visibles, au moyen de la détermination d'orientation.
