An apparatus for determining a spatial position and orientation of a tracked measuring device includes a light detection and ranging (LIDAR) unit having at least one measurement channel configured to generate at least one measurement signal, and a control and evaluation unit including a reception unit configured to receive data from the tracked measuring device in wireless fashion, the LIDAR unit being configured to generate a LIDAR signal for the at least one measurement signal and to transfer said LIDAR signal to the control and evaluation unit, the apparatus having a synchronization channel integrated at least in part into the measurement channel of the LIDAR unit and configured to determine a synchronization information item, and the control and evaluation unit being configured to temporally synchronize the data of the tracked measuring device and the LIDAR signal by taking into account the at least one synchronization information item.

Method and apparatus for determining at least one spatial position and orientation of at least one tracked measuring device

An apparatus for determining at least one spatial position and orientation of at least one object with at least three retroreflectors is provided. The apparatus has at least one LIDAR unit with at least three measurement channels. The LIDAR unit has at least one illumination device, which is configured to produce at least one frequency modulated input light beam. The LIDAR unit has at least one first beam splitter, wherein the first beam splitter is configured to divide the input light beam among the measurement channels in parallel and/or in sequence. The measurement channels are each configured to produce at least one measurement signal. The LIDAR unit is configured to produce at least one LIDAR signal for the measurement signals. The apparatus has at least one evaluation unit, which is configured to determine the spatial position and orientation of the object from the LIDAR signal.

An apparatus for adjusting a beam path for tracking an object includes an illumination unit to generate an illumination light beam, an optical unit with a beam expander optical unit and a beam deflection unit, the beam expander optical unit being configured to divergently expand the illumination light beam and the beam deflection unit being configured to deflect the illumination light beam spatially about two different axes of rotation, a detector unit to capture a light beam reflected by the object in response to an illumination by the illumination light beam and to generate a measurement signal, an evaluation and control unit to evaluate the measurement signal and configured to determine a manipulated variable for setting an effective focal length of the beam expander optical unit and/or for setting a spatial alignment of the beam deflection unit based on the information item in respect of the illumination of the object.

Method for adjusting a beam path for tracking an object

In a method for detecting the deformation of objects (), a sequence of pictures of the object () is taken with a measurement method during the deformation of the object (). From the pictures, phase images are determined. To improve such method, there is formed the difference between the current phase image or the respective current phase image and the phase image of an initial state. This difference or these differences is/are evaluated and/or displayed on a visual display unit and/or stored.

Method and apparatus for detecting the deformation of objects

A procedure serves for the testing of tires by means of a testing system. The testing system includes a memory in which geometric data () of the tire () are stored, and at least one probe () for testing the tire () surface. To improve on such a device, the probe or probes () are positioned with due consideration for the geometric data (-) of the tire () for the testing of the tire () surface (FIG.).

Procedure and device for testing tires

A process serves to record the deformation of objects (). In order to facilitate reliable evaluation even in the case of relatively large deformations, during the deformation of the object () a sequence or series of images of the object is recorded with a measuring process. The differential between two sequential images is formed. These differentials are integrated (FIG.).

Process and apparatus for recording the deformation of objects

The present invention relates to an inspection apparatus for tires having a positioning device for the tire to be inspected and a laser inspection device. In accordance with the invention, the inspection device comprises several measuring heads, in particular laser measuring heads in order to reduce the inspection time. In accordance with one aspect of the invention, several observation units and associated lighting sources are integrated in each measuring head.
