摘要： In a method for determining the absolute coordinates of an object (1), the object (1) is exposed to light (3) through a projection grid (2). The light (4) reflected by the object 1 is registered by a sensor (5). The image picked up by the sensor is evaluated. In order to improve such a method, the projection grid (2) comprises a first grid with a first grid vector (G1), and a second grid with a second grid vector (G2) which differs from said first grid vector. The sensor (5) is arranged at a distance (b) from the projection grid (2) such that the projections (bx, by), of the base vector (b) leading from the first and from the second grids to the sensor (5), onto the associated grid vectors (G1, G2) differ in size.

摘要： In a method for the 3D digitalization of an object with variable surface a plurality of camera pictures of partial surfaces of the object (4) are taken and put together for determining the 3D coordinates of the partial surface of the object (4). Camera pictures are taken of partial surfaces of the object (4), which overlap at their edges. For each camera picture the 3D coordinates of the associated partial surface of the object (4) are determined. The 3D coordinates of these partial surfaces of the object (4) are matched and put together by a matching method. Each camera picture is divided into subframes (1.1-1.9, 2.1-2.9, 3.1-3.9) which overlap at their edges and which overlap with the subframes of adjacent camera pictures. To the subframes (1.1-3.9), the associated 3D coordinates from the camera pictures are assigned. The 3D coordinates of the subframes (1.1-3.9) are matched and put together by a matching method. The method can iteratively be carried out several times.

摘要： In a method for 3D digitization of an object (1), a plurality of camera images of the object are recorded and assembled to determine the 3D coordinates of the object. To improve such method, pictures are taken from the object (1), from which 2D feature points (11, 12, 13; 21, 22, 23) of the object (1) are determined. The 3D coordinates of the 2D feature points are determined. The 2D point correspondences (32, 32, 22) between the 2D feature points of a picture and the 2D feature points of another picture are determined. Several of these 2D point correspondences are selected, and an associated 3D transformation is determined. The quality of this 3D transformation is determined with reference to the transformed 3D coordinates of the 2D feature points. Valid 3D feature points are determined therefrom. For assembling the camera images of the object (1), the 3D coordinates of the valid 3D feature points are used.

摘要： The invention serves for the contour measurement and/or deformation measurement of an object, particularly a tire or a structural component of a composite material. The object is irradiated with light, particularly structured light, that is emitted by a radiation source and consists, in particular, of coherent light or partially coherent light, especially laser light. The light reflected by the object is picked up by a camera with an imaging sensor. In order to improve the image quality, a first image is produced with a first adjustment of the camera and/or the radiation source which is adapted to a first image region (13). In addition, a second image is produced with a second adjustment of the camera and/or the radiation source which is adapted to a second image region (12). Both images are combined (FIG. 5).
