摘要： A calibration system (100) is provided including an aperture layer (104), a lens layer (106), an optical filter (109), a pixel layer (110) and a regulator. The aperture layer (104) defines a calibration aperture (125). The lens layer (106) includes a calibration lens (108) substantially axially aligned with the calibration aperture (125). The optical filter (109) is adjacent the lens layer (106) opposite the aperture layer (104). The pixel layer (110) is adjacent the optical filter (109) opposite the lens layer (106) and includes a calibration pixel (112) substantially axially aligned with the calibration lens (108). The calibration pixel (112) detects light power of an illumination source (103) that outputs a band of wavelengths of light as a function of a parameter. The regulator modifies the parameter of the illumination source (103) based on a light power detected by the calibration pixel (112). Fig. 1

摘要： A stereoscopic imager system, comprising: a sensor array comprising a first plurality of photosensors and a second plurality of photosensors spaced apart from the first plurality of photosensors by a gap, the first plurality of photosensors and the second plurality of photosensors being configured to detect ambient light in a scene; a moving component coupled to the sensor array and operable to move the sensor array between a first position and a second position within a full rotational image capturing cycle; and a system controller coupled to the sensor array and the moving component. The system controller can be configured to: move a field of view of a sensor array by instructing the moving component to capture a first image of an object in the scene with the first plurality of photosensors from a first perspective at the first position, and to capture a second image of the scene of the object in the scene with the second plurality of photosensors from a second perspective at the second position; and calculate, based on the first image and the second image, a distance to the object using an optical baseline defined by the gap.

摘要： A LIDAR system can automatically determine, based on analysis of data collected from the sensor channels during operation, whether fog is present. If fog is present, the LIDAR system can operate in a fog mode, and if fog is not present, the LIDAR system can operate in a clear-air mode. The two modes can differ from each other with respect to the emitter signals and/or the signal processing applied to the sensor data.

摘要： Systems and methods are provided for processing lidar data. The lidar data can be obtained in a particular manner that allows reconstruction of rectilinear images for which image processing can be applied from image to image. For instance, kernel-based image processing techniques can be used. Such processing techniques can use neighboring lidar and/or associated color pixels to adjust various values associated with the lidar signals. Such image processing of lidar and color pixels can be performed by dedicated circuitry, which may be on a same integrated circuit. Further, lidar pixels can be correlated to each other. For instance, classification techniques can identify lidar and/or associated color pixels as corresponding to the same object. The classification can be performed by an artificial intelligence (AI) coprocessor. Image processing techniques and classification techniques can be combined into a single system.

摘要： Methods and systems can augment 360 degree panoramic LIDAR results (e.g., from a spinning LIDAR system) with color obtained from color cameras. A color-pixel-lookup table can specify the correspondence between LIDAR pixels (depth/ranging pixels) and color pixels, which may be done at different viewing object distances. The operation of the color cameras can be triggered by the angular positions of the LIDAR system. For example, a color image of a particular camera can be captured when the LIDAR system is at a particular angular position, which can be predetermined based on properties of the cameras (e.g., shutter speed). Alternatively or in addition, a common internal clock can be used to assign timestamps to LIDAR and color pixels as they are captured. The corresponding color pixel(s), e.g., as determined using a color-pixel-lookup table, with the closest timestamp can be used for colorization.

摘要： A light ranging system can include a laser device and an imaging device having photosensors. The laser device illuminates a scene with laser pulse radiation that reflects off of objects in the scene. The reflections can vary greatly depending on the reflecting surface shape and reflectivity. The signal measured by photosensors can be filtered with a number of matched filter designed according to profiles of different reflected signals. A best matched filter can be identified, and hence information about the reflecting surface and accurate ranging information can be obtained. The laser pulse radiation can be emitted in coded pulses by allowing weights to different detection intervals. Other enhancements include staggering laser pulses and changing an operational status of photodetectors of a pixel sensor, as well as efficient signal processing using a sensor chip that includes processing circuits and photosensors.

摘要： Embodiments describe optical imagers that include one or more micro-optic components. Some imagers can be passive imagers that include a light detection system for receiving ambient light from a field. Some imagers can be active imagers that include a light emission system in addition to the light detection system. The light emission system can be configured to emit light into the field such that emitted light is reflected off surfaces of an object in the field and received by the light detection system. In some embodiments, the light detection system and/or the light emission system includes micro-optic components for improving operational performance.
