The invention pertains to a photogrammetric process for three-dimensional tracking of moving objects (1) whose location and bearing as a function of time is recorded from different directions in a time-pulse manner by a plurality of cameras (3, 4) whose simultaneously recorded images are evaluated by means of multi-image triangulation for position and bearing taking of the object as a function of time. The invention provides in addition that as the images are recorded the object (1) is synchronously illuminated (2), thus in particular significantly reducing ambient light influences as well as other interferences.
L'invention concerne un procédé photogrammétrique pour la poursuite tridimensionnelle d'objets en mouvement (1) dont la position et l'azimut en fonction du temps sont enregistrés, depuis différentes directions et par impulsions de temps, par une pluralité de caméras (3, 4) dont les images enregistrées simultanément sont évaluées par triangulation multi-image en vue de relever la position et l'azimut de l'objet en fonction du temps. Selon l'invention, à mesure que les images sont enregistrées, l'objet (1) est éclairé de manière synchrone (2), ce qui réduit considérablement notamment les influences lumineuses ambiantes ainsi que d'autres interférences.
