Abstract: One example of a method for processing a raw image of a time-of-flight (ToF) camera includes determining a phase-related value within a tracking region of the raw image and using calibration data to determine a distance corresponding to the phase-related value. One example furthermore includes a situation-dependent production of calibration data. One example shows how location tracking of an object, in particular with respect to its distance, is provided by the method. Further examples show an image processing apparatus of a ToF camera, a ToF camera, and a computer program product.

Abstract: An apparatus comprises an input interface for receiving a color image of at least an object and a low resolution depth image of at least the object. The apparatus further comprises an image processing module configured to produce data for generating a three-dimensional color image based on a first color pixel image data of a first color pixel and a first derived depth pixel image data of a first derived depth pixel. The image processing module is configured to calculate the first derived depth pixel image data based on a measured depth pixel image data of a measured depth pixel and a weighting factor. The weighting factor is based on a color edge magnitude summation value of a path between the first color pixel and the reference color pixel. The apparatus further comprises an output interface for providing the generated three-dimensional color image.

Abstract: A scanning system includes a transmitter, a scanning structure, and a controller. The transmitter is configured to transmit a frequency modulated continuous wave (FMCW) light beam that includes a plurality of frequency ramps including up-chirps and down-chirps that are matched into up-down chirp pairs. The scanning structure is configured to oscillate about a scanning axis such that a deflection angle of the scanning structure continuously varies over time in an angular range between two maximum deflection angles. The controller is configured to segment the angular range into a plurality of sub-angular ranges and assign each up-down chirp pair to a different sub-angular range of the plurality of sub-angular ranges. Each up-down chirp pair includes an up-chirp transmitted in an assigned sub-angular range during a first scanning movement of the scanning structure and a down-chirp transmitted in the assigned sub-angular range during a second scanning movement of the scanning structure.

Abstract: A light detection and ranging (LIDAR) system is provided. The LIDAR system comprises at least two lasers configured to emit aligned beams of light and a mirror configured to deflect the beams of light emitted by the lasers. The mirror is supported to be pivotable with respect to an axis of the mirror so as to allow the beams of light to scan a field of view of the LIDAR system. The LIDAR system further comprises a driver configured to drive the mirror into oscillations and a controller. The controller is configured to control at least one laser so as to selectively change a size of the field of view and/or to control the driver so as to selectively change the size of the field of view.

Abstract: An oscillator control system includes an oscillator structure configured to oscillate about first and second rotation axes according to a Lissajous pattern, wherein an oscillation about the second rotation axis imparts a cross-coupling error onto an oscillation about the first rotation axis, and wherein the cross-coupling error changes in accordance with a Lissajous position within the Lissajous pattern; and a driver circuit that includes a phase-locked loop (PLL) configured to regulate a driving signal that drives the oscillation about the first rotation axis. The PLL is configured to generate a PLL signal based on a phase error of the oscillation about the first rotation axis. The PLL includes a compensation circuit configured to receive the PLL signal and the Lissajous position within the Lissajous pattern, apply a compensation value to the PLL signal to generate a compensated PLL signal used for generating the driving signal based on the Lissajous position.
