  • Patent number: 11391843
    Abstract: The current disclosure describes a stereo imaging system that is configured to use Time-of-Flight (“Tof”) techniques to aid in stereoscopic image processing. One process disclosed uses ToF to aid in identifying the same elements (e.g., pixel clusters) in stereo image pairs by narrowing down search areas for matching. Another process uses ToF to aid in identifying the same elements in stereo image pairs where there a small amount texture making it difficult to find a match.

  • Publication number: 20220069542
    Abstract: Illuminator modules having improved safety features are described. In some implementations, light to be emitted from a module is produced by a light source, and light reflected by an optical component disposed over the light source is detected by a photodetectors. A distribution of the reflected light detected by the photodetectors is monitored, and an optical output power of the light source is regulated if it is determined, based on the monitored distribution of light, that an unsafe level of light may be emitted from the module.

  • Publication number: 20220003865
    Abstract: An apparatus includes a time-of-flight (TOF) sensor system that has an illuminator operable to emit pulses of light toward an object outside the apparatus. The illuminator is operable in a first mode in which the illuminator emits pulses having a first width and a second mode in which the illuminator emits pulses having a second width longer than the first width. The TOF sensor system further includes a photodetector operable to detect light produced by the illuminator and reflected by the object back toward the apparatus. An electronic control device is operable to control emission of light by the illuminator and is operable to estimate a distance to the object based on a time elapsed between an emission of one or more of the pulses by the illuminator and detection of the reflected light by the photodetector.

  • Publication number: 20210270946
    Abstract: In an example implementation, a first light measurement is obtained using a photodetector of a sensor module. The first light measurement corresponds, at least in part, to ambient light in an environment of the sensor module. Modulated light is generated using a light source of the sensor module, and a second light measurement is obtained using the photodetector of the sensor module. The second light measurement corresponds, at least in part, to modulated light reflected from an object toward the photodetector. A distance between the sensor module and the object is estimated, using an electronic control device, based on the first measurement, the second light measurement, and the modulated light.

  • Publication number: 20210156976
    Abstract: A method of using an optical TOF module to determine distance to an object. The method includes acquiring signals in the TOF module indicative of distance to the object, using a first algorithm to provide an output indicative of the distance to the object based on the acquired signals, using at least one second different algorithm to provide an output indicative of the distance to the object based on the acquired signals, and combining the outputs of the first and at least one second algorithms to obtain an improved estimate of the distance to the object. In some implementations, each of the first and at least one second algorithms further provides an output representing a respective confidence level indicative of how accurately distance to the object has been extracted by the particular algorithm.

  • Patent number: 10663691
    Abstract: The present disclosure describes imaging techniques and devices having improved autofocus capabilities. The imaging techniques can include actively illuminating a scene and determining distances over the entire scene and so that a respective distance to each object or point in the scene can be determined. Thus, distances to all objects in a scene (within a particular range) at any given instant can be stored. A preview of the image can be displayed so as to allow a user to select a region of the scene of interest. In response to the user's selection, the imager's optical assembly can be adjusted automatically, for example, to a position that corresponds to optimal image capture of objects at the particular distance of the selected region of the scene.

  • Patent number: 10578739
    Abstract: An optoelectronic module operable to acquire distance data and spectral data includes an array of demodulation pixels and an array of spectral filters. The demodulation pixels can possess an intrinsic wavelength-dependent sensitivity, wherein the intrinsic wavelength-dependent sensitivity can be offset by an intensity balancing micro-lens array in some cases. In some cases, the intrinsic wavelength-dependent sensitivity can be offset by a combined filter array, while in other cases the intrinsic wavelength-dependent sensitivity can be offset by an intensity balancing filter array. Still in other cases, the demodulation pixels can be operable in such as to offset the intrinsic wavelength-dependent sensitivity.
