Abstract: The disclosed LiDAR systems and methods are for object detection. The LiDAR system for object detection comprising: i) a receiver configured to receive a light signal reflected from an object; ii) a digital converter configured to convert the received light signal into a digital signal; iii) a pre-processor configured to pre-process the digital signal based on median filtering and to generate a pre-processed signal corresponding to the digital signal; and iv) a processor configured to analyze the pre-processed signal based on a threshold technique to detect a presence of the object.

Abstract: A detection and communication system, a control apparatus, and a detection system are disclosed, and may be applied to fields such as augmented reality AR, virtual reality VR, or vehicle-road synergy. The detection and communication system includes: N radars, configured to: separately search for a target, and separately align with the target, where N is an integer greater than 1, K radars that are in the N radars and that align with the target are configured to communicate with the target, N-K radars other than the K radars are configured to track and point the target, and K is a positive integer less than N. The N radars separately align with the target, to help improve precision of alignment between the radar and the target. In addition, some of the N radars may communicate with the target.

Abstract: There is provided a method and device for time-of-flight (TOF) ranging. The method includes generating, by each photon detector in a photon detector array, a quantized current pulse each time a predefined number of photons is detected. The method further includes summing, by a current adder, the quantized current pulses from all photon detectors to create an analog signal pulse. The method further includes providing, by a peak detector, a digital pulse for each instance where an intensity of the analog signal pulse is greater than signal peaks already measured after the last emitted pulsed laser shot. The method further includes measuring and recording, by a time-to-digital converter (TDC), a TOF each time the digital pulse is provided. The method further includes providing, by a TOF output, a single TDC result indicative of a TOF associated with the analog signal pulse having a highest intensity. The device includes a photon detector, current adder, analog peak detector and a time-of-flight digital converter, wherein each component is configured to perform the respective aspect of the method.
