摘要： A sensor system that obtains and processes time-of-flight data (TOF) is provided. A TOF sensor obtains raw data describing various surfaces. A processor applies an averaging filter to the raw data to smooth the raw data for increasing signal-to-noise ratio (SNR) of flat surfaces represented in the raw data, performs a depth compute process on the raw data, as filtered, to generate distance data, generates a point cloud based on the distance data, and identifies the Z-planes in the point cloud.

摘要： A LiDAR system (400) includes a light source (410) to generate light pulses, a mechanical scanner (402), a detector (414) including an array of discrete detector channels to convert light input into electrical signals, a lens (412) that focuses both light pulses generated at the light source onto the mechanical scanner and returning light (432) reflected from the mechanical scanner for reception in sequence by the detector channels, a first analog to digital converter, ADC (454), connected to each of the detector channels in the array and to convert the electrical signals from the detector channels into digital data signals, and a signal processor (456) coupled to the ADC to receive the digital data signals therefrom and to generate images of targets in a field of view of the LiDAR system from the digital data signals. The LiDAR system counteracts the effect of angle offset on detection induced by the rotating scanning mirror. Moreover, the lens transforms the reflection angle offset into a positional offset on the detector face. This positional offset becomes larger as the range to a target increases and cannot be tolerated. A fast-scanning mechanical LiDAR system may use a switch architecture to reduce the required number of ADC channels while overcoming angle lag. For example, if two laser pulses are emitted such that returning light may overlap on the detector due to the angle lag, two pairs of ADC channels may be used to detect returning light on two pairs of adjacent receive channels simultaneously.

摘要： Example embodiments relate to using cleaning protocols to monitor defects associated with light detection and ranging (lidar) devices. An example embodiment includes a method. The method includes applying, using a cleaning device, a cleaning protocol to one or more optical components of a light detection and ranging (lidar) device. The method also includes emitting, from a light emitter of the lidar device, one or more light signals. Additionally, the method includes detecting, by a light detector of the lidar device, reflections of the one or more light signals. Further, the method includes determining, by a controller of the lidar device based on the detected reflections of the one or more light signals, that one or more defects are present within the one or more optical components or within the cleaning device.

摘要： An electronic device includes a light detection and ranging (LiDAR) system including an Rx sensor including autofocus pixels distributed among image pixels for sensing image information. The LiDAR system also includes a Tx light source configured to output a pulse laser. A processor calculates a distance between the LiDAR system and a subject using the autofocus pixels included in the Rx sensor and drives the Tx light source based on the distance. The processor adaptively determines the transmission power of the Tx light source based on the distance to the subject, and controls the Tx light source to output a pulse laser according to the transmission power.
