Abstract: A depth camera assembly is used to obtain depth information describing a local area. The depth camera assembly includes a sensor having a plurality of pixels. Some or all of the pixels are divided into groups that are coupled to respective multi-purpose time-to-digital converters. Each multi-purpose time-to-digital converter comprises an oscillator and a counter. Each pixel in a group is associated with a multiplexer that is configured to select between inputs coupled to the pixel, the oscillator, or a counter associated with a different pixel. The multiplexer outputs the signal to the counter for the time-to-digital converter associated with the pixel. A time-of-flight measurement is taken during a first portion of an image frame. During a second portion of the image frame, the sensor may be used as an intensity counter. During a third portion of the image frame, the depth sensor may be calibrated.

Abstract: A projector for illuminating a target area is presented. The projector includes an array of emitters having a plurality of subarrays and an optical assembly. Each subarray includes one or more independently addressable channels emitting light in accordance with emission instructions. At least two of the subarrays are adjacent to each other and do not overlap. The optical assembly is configured to tile portions of the emitted light to form a light pattern for projection to a target area. The light pattern has a first plurality of sections and a second plurality of sections. Each section of the first plurality represents a first respective portion of the light pattern emitted from a corresponding subarray. Each section of the second plurality represents a second respective portion of the light pattern formed by tiling light emitted from two or more of the subarrays.

Abstract: Aspects of the present disclosure include a navigation system and computer-implemented methods for proactively re-routing vehicles based on an analysis of input component data obtained from the navigation-enabled devices. The navigation system scores the input component data to obtain a measure of frustration (e.g., a feeling of being upset or annoyed) of the user of the navigation-enabled device. The navigation system may provide a detour suggestion for display on the navigation-enabled device to persuade the user of the device to direct their vehicle to depart from its current location or route in an effort to remove the vehicle from traffic, and thereby reduce the frustration level of the user. The detour suggestion may include an alternative route to the original destination, or an alternative destination.

Abstract: A depth camera assembly (DCA) determines depth information. The DCA projects a dynamic structured light pattern into a local area and captures images including a portion of the dynamic structured light pattern. The DCA determines regions of interest in which it may be beneficial to increase or decrease an amount of texture added to the region of interest using the dynamic structured light pattern. For example, the DCA may identify the regions of interest based on contrast values calculated using a contrast algorithm, or based on the parameters received from a mapping server including a virtual model of the local area. The DCA may selectively increase or decrease an amount of texture added by the dynamic structured light pattern in portions of the local area. By selectively controlling portions of the dynamic structured light pattern, the DCA may decrease power consumption and/or increase the accuracy of depth sensing measurements.

Abstract: A binary depth mask model is trained for use in occlusion within a mixed reality application. The training leverages information about virtual object positions and depths that is inherently available to the system as part of rendering of virtual objects. Training is performed on a set of stereo images, a set of binary depth masks corresponding to the stereo images, and a depth value against which object depth is evaluated. Given this input, the training outputs the binary depth mask model, which when given a stereo image as input outputs a depth binary depth mask indicating which pixels of the stereo image are nearer, or father away, than the depth value. The depth mask model can be applied in real time to handle occlusion operations when compositing a given real-world stereo image with virtual objects.

Each pixel of the augmented sensor includes a plurality of charge bins, and charge accumulated by a photodiode of a pixel during different time intervals (e.g., times when different sinusoidal patterns are emitted) is stored in a different charge storage bin. Charge may be retrieved from different charge storage bins to determine depth from the DCA.

Abstract: A depth estimation system is described capable of determining depth information using two images from two cameras. A first camera captures a first image and a second camera captures a second image, both images including a plurality of light channels. A scan direction is selected from a plurality of scan directions. For the selected scan direction, along each of a plurality of scanlines, the system compares pixels from the first image to pixels from the second image. The comparison is based on calculating a census transform for each pixel in the first image and a census transform for each pixel in the second image. This comparison is used to determine a stereo correspondence between the pixels in the first image and the pixels in the second image. The system generates a depth map based on the stereo correspondence.

Abstract: A device for moving an object is disclosed. The device has a drive cylinder with drive grooves and a set of idler pulleys. The idler pulleys are on a shaft that is parallel to the drive cylinder. Each of the idler pulleys rotate at an angle around the drive shaft that aligns the grooves of the idler pulleys to neighboring drive grooves. This allows the line to pass onto the drive groove, around an idler pulley, and onto a next adjacent drive groove. The line therefore winds back and forth between the drive grooves, the idler pulleys, and back to the next drive groove. One end of the line is placed under tension and the other is attached to an object or to a fixed member. The drive cylinder is driven and the line is moved through the device, or the device is moved along the line, respectively.
