A device for generating a photometric stereo image and a color image of an object which is moved at a predetermined relative speed relative to the device. The device includes a lighting area and a lighting arrangement which is oriented to the lighting area. The lighting arrangement cyclically emits a lighting sequence in the lighting area. The lighting sequence has at least four lighting pulses each of which have a wavelength range and a lighting direction. At least three of the at least four lighting pulses have a different wavelength range, and at least two of the at least four lighting pulses have a different lighting direction and a same wavelength range.

A process includes receiving a target quality value, receiving a measured quality value, receiving a source quality value, and sending a source control instruction. The source control instruction is based at least in part on the target quality value, the measured quality value, and the source quality value. The target quality value, the measured quality value, the source quality value, and the source control instruction are communicated via the communication port. The measured quality value is generated by an inspection device configured to inspect a sample. The source quality value is associated with a quality level of a first group of samples. The target quality value indicates a desired quality value of an output group of samples. The source control instruction causes a source selecting device to select one of a plurality of groups of samples, each group having identified quality characteristics.

An apparatus is described that includes an integrated two-dimensional image capture and three-dimensional time-of-flight depth capture system. The three-dimensional time-of-flight depth capture system includes an illuminator to generate light. The illuminator includes arrays of light sources. Each of the arrays is dedicated to a particular different partition within a partitioned field of view of the illuminator.

In one embodiment, the apparatus comprises a calibration unit operable to perform a single view calibration process using a captured single view a target having a plurality of plane geometries having detectable features and being at a single orientation and to generate calibration parameters to calibrate one or more of the projector and multiple cameras using the single view of the target.

An illumination apparatus for reducing speckle effect in light reflected off an illumination target includes a laser; a linear diffuser positioned in an optical path between an illumination target and the laser to diffuse collimated laser light in a planar fan of diffused light that spreads in one dimension across at least a portion of the illumination target; and a beam deflector to direct the collimated laser light incident on the beam deflector to sweep across different locations on the linear diffuser within an exposure time for illumination of the illumination target by the diffused light. The different locations span a distance across the linear diffuser that provides sufficient uncorrelated speckle patterns, at an image sensor, in light reflected from an intersection of the planar fan of light with the illumination target to add incoherently when imaged by the image sensor within the exposure time.

A device for detecting the surroundings of a vehicle and a method for detecting the surroundings, and a vehicle designed to carry out said method comprise a camera module, a camera control apparatus, an analysis unit and an illumination device. The illumination device is formed by a matrix headlight of the vehicle and is designed such that it can project a light pattern into the surroundings. The projected light pattern is imaged in the detection region of the camera module and the 3D position of measurement points formed by the light pattern in the surroundings is determined by the analysis unit. However, the illumination device projects the light pattern only into regions of the surroundings in which the analysis unit has ascertained, based on image data, a value that is critical for 3D position determination.
