Abstract: A method and system for generating depth in monocular images acquires multiple sets of binocular images to build a dataset containing instance segmentation labels as to content; training an work using the dataset with instance segmentation labels to obtain a trained autoencoder network; acquiring monocular image, the monocular image is input into the trained autoencoder network to obtain a first disparity map and the first disparity map is converted to obtain depth image corresponding to the monocular image. The method combines binocular images with instance segmentation images as training data for training an autoencoder network, monocular images can simply be input into the autoencoder network to output the disparity map. Depth estimation for monocular images is achieved by converting the disparity map to a depth image corresponding to the monocular image. An electronic device and a non-transitory storage are also disclosed.

Abstract: A system for executing a three-dimensional (3D) intraoperative scan of a patient is disclosed. A 3D scanner control computing device projects the object points included onto a first image plane and the object points onto a second image plane. The 3D scanner control computing device determines first epipolar lines associated with the first image plane and second epipolar lines associated with the second image plane based on an epipolar plane that triangulates the object points included in the first 2D intraoperative image to the object points included in the second 2D intraoperative image. Each epipolar lines provides a depth of each object as projected onto the first image plane and the second image plane. The 3D scanner control computing device converts the first 2D intraoperative image and the second 2D intraoperative image to the 3D intraoperative scan of the patient based on the depth of each object point provided by each corresponding epipolar line.

Abstract: Systems, apparatuses and methods may provide for technology that generates, by a first neural network, an initial set of model weights based on input data and iteratively generates, by a second neural network, an updated set of model weights based on residual data associated with the initial set of model weights and the input data. Additionally, the technology may output a geometric model of the input data based on the updated set of model weights. In one example, the first neural network and the second neural network reduce the dependence of the geometric model on the number of data points in the input data.

Abstract: A high-resolution image sensor suitable for use in an augmented reality (AR) system to provide low latency image analysis with low power consumption. The AR system can be compact, and may be small enough to be packaged within a wearable device such as a set of goggles or mounted on a frame resembling ordinary eyeglasses. The image sensor may receive information about a region of an imaging array associated with a movable object, selectively output imaging information for that region, and synchronously output high-resolution image frames. The region may be updated dynamically as the image sensor and/or the object moves. The image sensor may output the high-resolution image frames less frequently than the region being updated when the image sensor and/or the object moves. Such an image sensor provides a small amount of data from which object information used in rendering an AR scene can be developed.

Abstract: A distance measurement system comprises distance measurement devices, including a LiDAR sensor and at least one other distance measurement device, and a storage device storing three-dimensional point cloud data based on distance measurement data acquired by each of the distance measurement devices. The LiDAR sensor comprises a light-emitting device that can change an emission direction of a light beam, a light-receiving device that detects reflected light from the light beam and outputs a signal indicating a detection result, and a processing circuit that controls the light-emitting device and the light-receiving device to generate the distance measurement data on a basis of the signal outputted from the light-receiving device. The processing circuit references the point cloud data to determine at least one empty area in the point cloud data, and measures distance in the empty area by causing the light-emitting device to emit the light beam toward the empty area.

Abstract: A system includes a sensor including a set of cameras configured to capture a set of images of an enclosed space. The system further includes a processor and a non-transitory computer-readable medium containing instructions which, when executed on the processor, cause the processor to perform operations including: (a) receiving the set of images captured by the set of cameras; (b) pre-processing the set of images to increase quality and reduce effect of ambient lighting; (c) building a disparity map for the set of images based at least in part on a relationship between the set of cameras; and (d) determining an occupancy of the enclosed space based at least in part on the disparity map. The system can be used to determine occupancy in a trailer with irregularly shaped cargo using low cost sensors.
