ABSTRACT:
The invention concerns a device for three-dimensional photogrammetric capture of an object with time resolution, comprising a first auxiliary assembly set on the object to be captured, a second auxiliary assembly and a single camera. The first auxiliary assembly is mobile relative to the second auxiliary assembly. The camera is placed, relative to the first and second auxiliary assemblies, so as to capture a relative movement between said two auxiliary assemblies and hence the position of the object according to a single perspective. The inventive method is characterised in that it comprises the following steps: preparing a first auxiliary assembly set on the object to be captured; preparing a second auxiliary assembly, relatively to which the object can move; and capturing, according to a single perspective, the relative position of the object, on the basis of the initial position of the first and second assemblies.
