29571

Abstract:

Described herein a technique for constructing a complementary MOS device on a sapphire substrate so that the surface of the device is planarized, the P-channel and N-channel devices are in substantially correct registration, the threshold voltage for the back-channel leakage effect inherent in sapphire substrate device to occur is increased, and the areas of gate oxidation are pseudo self-aligned so as to minimize overlap of the gate oxide with the source and drain regions.

International Classification:

G06K 9/00
G05D 1/00
G06F 13/16

Abstract:

The disclosure is generally directed to systems and methods for sharing a video feed of a camera among multiple image processing components in a vehicle. A first priority may be applied to a first image processing component that performs a first image processing function. A second priority that is lower than the first priority, is applied to a second image processing component that performs a second image processing function. The first function may be deemed more important than the second function due to various reasons. Consequently, the first image processing component is offered priority to apply a first set of camera settings on the camera. The second image processing component may prefer to apply a different set of camera settings for executing the second image processing function. An access arbitrator allows the second image processing component to do so when the first image processing component relinquishes control of the camera.

International Classification:

G06K 9/00

Abstract:

A processing system comprises a processor and a memory. The memory stores instructions executable by the processor to receive a polarimetric image from a polarimetric camera sensor, and to identify a road surface in the received image based on a vehicle location, an orientation of the camera sensor, and a vehicle pose. The memory stores instructions, upon identifying, in the polarimetric image, polarized light reflections from the identified road surface based on a polarization direction and a polarization degree determined from the polarimetric image, to remove the identified polarized light reflections from the polarimetric image, thereby generating an updated polarimetric image including generating a de-mosaicked imaged based on the identified polarized light reflections, wherein the identified polarized light reflections are ignored at de-mosaicking, and to identify a road feature including a lane marking based on the updated polarimetric image.

Inventors:

- Dearborn MI, US
David Michael HERMAN - Oak Park MI, US

International Classification:

G08G 1/01
H04W 4/46

Abstract:

A vehicle may determine that it is stopped and detect a perimeter-modification event predefined as correlating to a changed vehicle perimeter. The vehicle may further, responsive to the perimeter-modification event, define an expanded vehicle perimeter, larger than a perimeter predefined as representing the vehicle in travel. The perimeter expansion may be done in accordance with a predefined modification associated with the detected perimeter modification event. The vehicle may additionally wirelessly share the expanded vehicle perimeter with at least one other vehicle.

Inventors:

- Dearborn MI, US
David Michael Herman - Oak Park MI, US

Assignee:

Ford Global Technologies, LLC - Dearborn MI

International Classification:

H04N 5/235

Abstract:

Systems, methods, and computer-readable media are disclosed for reducing flickering artifacts in imaged light sources. Example methods may include receiving images corresponding to a scene captured by a camera; determining a light source in the scene using at least one artificial intelligence (AI)-based algorithm; determining, using an event-based camera, data representing flickering of the light source, the flickering having a frequency; determining, based on the data, that a time duration of overlap between an on state of the light source and an exposure time of the camera is below a threshold; and delaying the exposure time of the camera by a delay time to increase the time duration of overlap.

G05D 1/00

Abstract:

Systems, methods, and computer-readable media are disclosed for automated multimodal delivery. Example methods may include determining information associated with the delivery; determining, based on at least a first portion of the information, that a first confidence level indicative of a delivery capability using a first vehicle is above a first threshold; and determining, based on at least a second portion of the information, a second confidence level indicative of a delivery preference for delivery using the first vehicle relative to a second vehicle.

International Classification:

G06K 9/00
G06K 9/46
G06K 9/62
G06T 7/586
H04W 4/40

Abstract:

Abandoned articles left by a user departing from an autonomous vehicle are automatically detected by capturing image data including a plurality of diversely-illuminated images of a target area within a passenger cabin of the vehicle. A plurality of normal vectors are determined for respective pixels representing the target area in a normal extractor based on the images. A normal-driven map is stored in a first array in response to the plurality of normal vectors. A baseline map is stored in a second array compiled from baseline images of the target area in a nominal clean state. Differences between the normal-driven map and the baseline map indicative of an object not present in the clean state are detected in a comparator. Difficult to detect objects can be found using a single, fixed camera.

H04N 5/232

Abstract:

Vehicles and methods are described for improved vehicle camera functionality. An example vehicle includes a CMOS camera, lights, and an imaging controller. The imaging controller is configured to capture a plurality of image frames by, for each image frame: exposing one or more rows of the CMOS camera at a time, and pausing exposure during a frame time gap after capturing a last row of the CMOS camera. The imaging controller is also configured to, for one or more of the plurality of image frames: operate the one or more lights at a reduced intensity level during a first section of the image frame, wherein the reduced intensity level is lower than a maximum average intensity level; and operate the one or more lights at an increased intensity level during a second section of the image frame, wherein the increased intensity level is higher than the maximum average intensity level.
