  • Publication number: 20230206497
    Abstract: A camera monitoring system includes a first mirror replacement camera extending outward from a vehicle. The first mirror replacement camera defines a rearward facing field of view including at least one image feature during at least a first set of operating conditions. The at least one image feature has a fixed position within the field of view during the at least the first set of operating conditions. A camera monitoring system controller is configured to automatically calibrate an orientation of the first mirror replacement camera relative to the vehicle by comparing an expected position of the at least one image feature to an actual position of the at least one image feature while the vehicle is operating under the first set of operating conditions and identifying a shift of camera orientation based on the difference.

    Abstract: In certain embodiments, an ophthalmic laser surgical system for imaging and treating a target in an eye includes an imaging system with an optical coherence tomography (OCT) device that directs an OCT imaging beam along an imaging beam path towards the target in the eye, and generates OCT images from the OCT imaging beam reflected from the eye. The beam combining and alignment device aligns the OCT imaging beam and the laser beam. The laser-OCT xy-scanner: receives the OCT imaging beam from the imaging system, directs the OCT imaging beam along the imaging beam path towards the eye, and scans the OCT imaging beam in an xy-plane in the eye; and receives the laser beam from the laser device, directs the laser beam along the laser beam path aligned with the imaging beam path towards the eye, and scans the laser beam in the xy-plane in the eye.

  • Publication number: 20230157536
    Abstract: In certain embodiments, an ophthalmic laser surgical system for imaging and treating a target in an eye includes an optical coherence tomography (OCT) device that: directs an imaging beam towards the eye; generates three-dimensional (3D) image data from the imaging beam reflected from the eye; and generates two-dimensional (2D) enface images from the 3D image data. The 2D enface images include a target enface image imaging the target in the eye and a retinal enface image imaging a shadow cast by the target onto the retina. An xy-scanner directs the imaging beam along an imaging beam path towards the eye, and directs a laser beam from the laser device along a laser beam path aligned with the imaging beam path towards the eye. A computer compares the target of the target enface image and the shadow of the retinal enface image to confirm the presence of the target.

  • Publication number: 20230157538
    Abstract: In certain embodiments, an OCT system sends a sample beam to a sample (e.g., an eye) along a sample path divided into multiple sample path ranges. The system sends a reference beam to a reference arm system with multiple reference arms, where each reference arm corresponds to a sample path range. Each arm has a specific dispersion level with a corresponding dispersion compensation parameter set designed to address the specific level. A detector detects reflected sample and reference beams. A computer performs the following for each sample path range: select the dispersion compensation parameter set corresponding to the reference arm of the sample path range; apply the dispersion compensation parameter set to the detector signal to yield image information; and process the image information. The computer generates an image of the sample from the image information for the sample path ranges.

  • Publication number: 20220396322
    Abstract: A method for determining a trailer detection parameter of a trailer including receiving an image from at least one camera at a controller. The at least one camera defines a field of view including at least a portion of a vehicle trailer. The method determines a trailer angle of the vehicle trailer relative to a tractor, identifies at least one feature in an image of the trailer, determines a two-dimensional distance from the at least one feature to a predefined position on the image, and converts the two-dimensional distance to a three-dimensional distance based at least in part on the determined angle. The three-dimensional distance is a trailer detection parameter of the trailer.

  • Patent number: 10743763
    Abstract: Methods for improved acquisition and processing of optical coherence tomography (OCT) angiography data are presented. One embodiment involves improving the acquisition of the data by evaluating the quality of different portions of the data to identify sections having non-uniform acquisition parameters or non-uniformities due to opacities in the eye such as floaters. The identified sections can then be brought to the attention of the user or automatically reacquired. In another embodiment, segmentation of layers in the retina includes both structural and flow information derived from motion contrast processing. In a further embodiment, the health of the eye is evaluating by comparing a metric reflecting the density of vessels at a particular location in the eye determined by OCT angiography to a database of values calculated on normal eyes.

  • Patent number: 9759544
    Abstract: A method for reducing motion artifacts in optical coherence tomography (OCT) angiography images is disclosed. The method is applied to the intensity or complex OCT data prior to applying the motion contrast analysis and involves determining sub-pixel level shifts between at least two B-scans repeated approximately at the same location and applying the sub-pixel level shifts to the B-scans to be able to correct for motion and accurately determine motion contrast signal. A preferred embodiment includes the use of 2D cross correlations to register a series of B-scans in both the axial (z-) and lateral (x-) dimensions and a convolution approach to achieve sub-pixel level frame registration.
