摘要： A method for calibrating a set of laser profilometers, comprising the steps of: providing (41) at least two profilometers (11-14); providing (42) a calibration standard (20) having at least six reference points (21-26); scanning (43) the calibration standard (20) with the profilometers (11-14) such that at least six of the same reference points (21-26) are visible on scans made by at least two of the profilometers (11-14); detecting (44) the position of the reference points (21-26) in the three axes (X, Y, Z) for each profilometer (11-14) on its corresponding scan, and defining their positions relative to the specified profilometer (11-14) in the local coordinate system of the particular profilometer; sorting (45) the scanned reference points (21-26) by assigning a label to each point in such a way that each scan comprises the same labels for the same reference point (21-26); and calculating (46) a transformation matrix for the coordinates of the reference points of each profilometer in order to transform these coordinates from the local coordinate system of each profilometer to the external coordinate system.

摘要： The present invention relates to an enhanced image calibration and monitoring apparatus and method for calibrating and monitoring an imaging of a camera of a vehicle. A predetermined light pattern is emitted by a lighting unit, for instance a headlight of a vehicle. The headlight of the vehicle may be configured as a digital light processing projector or a liquid crystal display projector. The emitted light pattern is projected at least partly in the field of view of a camera. After capturing the emitted light pattern by this camera, the image data provided by the camera are analysed in order to determine calibration or monitoring parameters of the camera. In this way, an automated calibration and monitoring of an optical system may be obtained. By using the headlights of the vehicle for emitting the light pattern, no further light sources are required. Hence, the costs for such a calibration and monitoring can be reduced.

摘要： The invention relates to a method and an assembly for generating optical split images. The invention permits the three-dimensional, layered optical scanning of spatially extended objects (10) and is used in microscopy, but is not limited to this field. In said method, periodically distributed exposures (3) are projected in one spatial direction into a plane (9) and fluorescent and/or luminescent light that is reflected and/or scattered and/or emitted by the sample (10) is reproduced on a local-resolution detector (11). According to the invention, a calibration step is first carried out, in which step the local phase and/or the local period of the distributed exposures are determined for each location on the detector (11). In the sample detection mode, two distributed exposures are projected into or onto the sample (10) to calculate each split image and the resultant intensity distributions are reproduced on the detector (11). The method steps for projecting and detecting two exposure light distributions are repeated as often as desired, in particular for different focal positions of the sample (10) and/or different exposure wavelengths and the intensity distributions are used to calculate at least one optical split image from the captured intensity distributions with the aid of the local phase and/or local period.

摘要： A method for optically determining a physical attribute of a moving object, such as the height h of the carbons (14) of a pantograph head (10). This method incorporates a method for optically establishing a mathematical spatial relationship between one or more cameras (26) and one or more fanned lasers (24) each capable of projecting a laser beam along a laser plane (28). The method comprises: establishing an orientation and location of each camera (26) with respect to a co-ordinate system; establishing an orientation of each laser plane (28) within the co-ordinate system; and deriving a transformation function for calculating the three dimensional position of points within the plane (28) of each respective laser beam from a pixel location within a pixelated image created by each of the cameras.
