Abstract: Various technologies described herein pertain to mitigating motion misalignment of a time-of-flight sensor system and/or generating transverse velocity estimate data utilizing the time-of-flight sensor system. A stream of frames outputted by a sensor of the time-of-flight sensor system is received. A pair of non-adjacent frames in the stream of frames is identified. Computed optical flow data is calculated based on the pair of non-adjacent frames in the stream of frames. Estimated optical flow data for at least one differing frame can be generated based on the computed optical flow data, and the at least one differing frame can be realigned based on the estimated optical flow data. Moreover, transverse velocity estimate data for an object can be generated based on the computed optical flow data.

Abstract: Aspects of disclosed technology provide solutions for reducing interference between optical sensors and in particular, for eliminating crosstalk interference between proximally positioned Light Detection and Ranging (LiDAR) sensors (e.g., flash LiDAR sensors or full-field LiDAR sensors). A process of the disclosed technology can include steps for determining a center modulation frequency for a first Light Detection and Ranging (LiDAR) sensor, scheduling a first capture sequence for the first LiDAR sensor to occur at a first time, determining a center modulation frequency for a second LiDAR sensor, and scheduling a second capture sequence for the second LiDAR sensor to occur at a second time. Systems and machine-readable media are also provided.

Abstract: Aspects of the disclosed technology provide solutions for enabling vehicle-to-vehicle communications and in particular, for providing optical communication capabilities using Light Detection and Ranging (LiDAR) sensors. In some aspects, the disclosed technology encompasses solutions for utilizing LiDAR sensors to engage in Vehicle-to-Everything (V2X) communications. A LiDAR sensor of the disclosed technology can include a processing unit, an image-sensor coupled to the processing unit, and a first array of photodetectors coupled to the processing unit, wherein the first array of photodetectors is disposed in an optical field of the optical lens and coupled to a top-edge of the image sensor, and wherein an integration rate for light signals received by the first array of photodetectors is faster than an integration rate for light signals received by the image-sensor.
