  • Publication number: 20210248780
    Abstract: A method of calibrating intrinsic parameters associated with a camera includes positioning a camera to receive collimated light from a rotatable collimator, wherein the collimated light is provided to the camera via a target having a central target aperture and a plurality of peripheral target apertures located on a periphery of the target. The method further includes rotating the collimator along a first axis extending through an entrance pupil location of the camera and recording spot positions associated with collimated light provided through one or more target apertures of the target at each first axis interval and determining a distortion profile associated with the camera based on the recorded spot positions measured at the plurality of first axis intervals.

  • Patent number: 11089197
    Abstract: A camera includes a phased metalens positioned between an objective lens and an imager of the camera. The phased metalens is configured to adjust a focus plane of an image in a field of view of the camera in response to changes in an operating temperature of the camera. The phased metalens adjusts the focus plane for multiple frequencies or wavelengths light such that all light wave-fronts exiting the phased metalens arrive at the imager at a same time.

  • Patent number: 11089188
    Abstract: The techniques of this disclosure relate to a system for adjusting a focus of an image. A system includes a phased metalens configured to adjust a focus of an image detected by an imaging substrate of an image sensor. The phased metalens is further configured to adjust a property of light that reaches the imaging substrate based on a change in a flatness of the imaging substrate. The property of the light that reaches the imaging substrate includes a phase of all the light that reaches the imaging substrate at a same time. The phased metalens accomplishes this by achieving near-diffraction-limited focusing over the incoming light wavelengths using precisely defined nanoscale subwavelength resolution structures.

  • Publication number: 20210225152
    Abstract: A method of detecting occupants within a vehicle includes receiving camera data, thermal data and radar data with respect to the vehicle. The received data is stored to at least a first buffer and a second buffer, wherein the first buffer has a length associated with a first duration of time and the second buffer has a length associated with a second duration of time greater than the first duration of time.

  • Patent number: 10754035
    Abstract: A ground-classifier system that classifies ground-cover proximate to an automated vehicle includes a lidar, a camera, and a controller. The lidar that detects a point-cloud of a field-of-view. The camera that renders an image of the field-of-view. The controller is configured to define a lidar-grid that segregates the point-cloud into an array of patches, and define a camera-grid that segregates the image into an array of cells. The point-cloud and the image are aligned such that a patch is aligned with a cell. A patch is determined to be ground when the height is less than a height-threshold. The controller is configured to determine a lidar-characteristic of cloud-points within the patch, determine a camera-characteristic of pixels within the cell, and determine a classification of the patch when the patch is determined to be ground, wherein the classification of the patch is determined based on the lidar-characteristic and the camera-characteristic.

  • Publication number: 20200191926
    Abstract: A lidar unit includes a housing, a laser, a detector, a window, and a target. The housing is configured to define an opening. The laser and the detector are disposed within the housing. The laser is operable to direct (e.g. scan, steer) a beam of light through the opening toward a field-of-view. The detector is operable to detect a reflection of the beam by an object in the field-of-view. The window is disposed within the opening of the housing, and interposed between the object and the arrangement. The beam is projected by the laser and detected by the detector through the window. The target is disposed on the window. The target is configured to reflect the beam towards the detector. Operation of the laser is determined based on the reflection of the beam by the target towards the detector.

  • Publication number: 20200094677
    Abstract: An illustrative example object detection system includes a sensor having a field of view. The sensor is configured to emit radiation and to detect at least some of the radiation reflected by an object within the field of view. A panel in the field of view allows the radiation to pass through the panel. The panel being is configured to be set in a fixed position relative to a vehicle coordinate system. A plurality of reflective alignment markers are situated on the panel in the field of view. The reflective alignment markers reflect radiation emitted by the sensor back toward the sensor. A processor is configured to determine an alignment of the sensor with the vehicle coordinate system based on an indication from the sensor regarding radiation reflected by the reflective alignment markers and detected by the sensor.

    Abstract: A driver assistance system includes an imaging device mounted to a vehicle that provides an image of a vicinity of the vehicle. A mobile device carried by a driver provides range rate information regarding a change in position of the mobile device. A processor determines that there is at least one object in the vicinity of the vehicle based on the image, determines the speed of vehicle movement based on the range rate information, determines relative movement between the vehicle and the at least one object based on at least the image, and determines a risk of collision between the vehicle and the at least one object based on the determined speed and the determined relative movement. A driver assist output provides a risk indication of the determined risk of collision to the driver.
