Abstract: Aspects of the present disclosure involve example systems and methods for remote sensing of objects. In one example, a system includes a light source, a camera, a light radar (lidar) system, a region of interest identification circuit, and a range refining circuit. The region of interest identification circuit identifies a region of interest corresponding to an object and a first range of distance to the region of interest using the camera and the light source. The range refining circuit probes the region of interest to refine the first range to a second range of distance to the region of interest using the lidar system, the second range having a lower uncertainty than the first range.

Abstract: Aspects of the present disclosure involve example systems and methods for remote sensing of objects. In one example, a system includes a light source, a camera, a light source timing circuit, an exposure window timing circuit, and a range determination circuit. The light source timing circuit is to generate light pulses using the light source. The exposure window timing circuit generates multiple exposure windows for the light pulses for the camera, each of the multiple exposure windows representing a corresponding first range of distance from the camera. The range determination circuit processes an indication of an amount of light captured at the camera during an opening of each of the multiple exposure windows for one of the light pulses to determine a presence of an object within a second range of distance from the camera, the second range having a lower uncertainty than the first range.

Abstract: A system includes a memory storing computer-readable instructions and a processor to execute the instructions to perform operations including generating multiple exposure windows for light pulses for a camera, the multiple exposure windows having a sequence comprising a first exposure window having an opening for a duration of time and each other exposure window of the multiple exposure windows having an opening for the duration of time except for a closing for a subset of the duration of time corresponding to a distance from one of a light source and the camera, wherein none of the closings of the multiple exposure windows overlaps another closing of the multiple exposure windows and determining a difference between an indication of an amount of light captured at the camera during the first exposure window and each other exposure window of the multiple exposure windows.
