  • Publication number: 20250020455
    Abstract: A depth sensor device for measuring a depth map of an object comprises a projector unit configured to illuminate different locations of the object during different time periods with an illumination pattern, a receiver unit comprising a plurality of pixels, the receiver unit being configured to detect on each pixel intensities of light reflected from the object while it is illuminated with the illumination pattern, and to generate an event at one of the pixels if the intensity detected at the pixel changes by more than a predetermined threshold, and a control unit configured to generate for each of the different time periods a total number of detected events and pixel information indicating for each event the pixel that detected the event, and to calculate from the pixel information and the total number a position of the image of the illumination pattern on the pixels with sub-pixel accuracy.

  • Patent number: 11463637
    Abstract: According to the present invention there is provided a vision sensor comprising, an array of pixels comprising rows and columns of pixels, wherein each pixel in the array comprises, a photosensor which is configured to output a current proportional to the intensity of light which is incident on the photosensor; a current source which is configured such that it can output a current which has a constant current level which is equal to the current level of the current output by the photosensor at a selected first instant in time, and can maintain that constant current level even if the level of the current output from the photosensor changes after said selected first instant in time; an integrator which is configured to integrate the difference between the level of current output by the current source and the level of current output by the photosensor, after the selected first instant in time; wherein the vision sensor further comprises a counter which can measure time, wherein the counter is configured such tha

  • Patent number: 10262207
    Abstract: The present invention relates to a method for tracking a position of at least one keypoint in an image of an object moving relative to an optical sensor, wherein light reflected from the object (12) is detected so as to generate an image of the object, and wherein a position of at least one keypoint (Kj) in said image is detected and updated using temporal contrast events (Ev) of the optical sensor. The invention also relates to a corresponding computer program and device.
