摘要： Measuring speed of a vehicle in a road environment. During calibration, multiple images are captured of a calibration vehicle traveling at a known ground speed. A calibration image feature is located in the image of the calibration vehicle. An optical flow of the calibration image feature is computed to determine a model between an image speed of the calibration image feature and the known ground speed of the calibration vehicle. During speed measurement, multiple images are captured of a target vehicle traveling along a road surface at unknown ground speed. A target image feature may be located in an image of the target vehicle. An image speed may be computed of the target image feature. The model may be applied to determine the ground speed of the target vehicle from the image speed of the target image feature.

摘要： Systems and methods are described for display of a depth image (depth plus texture) using multiple focal planes. In one embodiment, a depth image (which may be a frame of a depth video, consisting of a video plus depth sequence) is mapped to a first set of image planes. The depth image (or a subsequent frame of the depth video) is mapped to a second set of image planes. Each image plane in the first and second set has a specified depth, and the first and second set differ in at least one depth. Each of the image planes is displayed in the first set at the respective depth of that image plane, and, subsequently, each of the image planes in the second set is displayed at its respective depth. Display of the first and second sets may be cyclically alternated at rate sufficiently high to avoid perceptible flicker.

摘要： A system and method for determining an absolute position of an object in an area is presented. The system includes a server having a processor, and a plurality of camera nodes coupled to the server. Each node includes a camera that acquires images of the object and area. The server receives image data from a camera, detects the object within an approximate location by image analysis techniques, and determines a relative position of the object in pixel coordinates. The processor then detects stationary markers proximate to the relative location of the object, determines an absolute position of the detected markers relative to known markers to define an absolute position of the marker, and determines an absolute location of the object in relation to the absolute location of the detected marker. This absolute position of the object is provided to an official to accurately locate the object in the area.

摘要： A video generation method includes: acquiring an original image corresponding to a target frame, and identifying a target object in the original image; according to a sliding zooming strategy, performing sliding zooming processing on an initial background image in the original image excluding the target object, so as to obtain a target background image, wherein the sliding zooming strategy is at least used for indicating a sliding direction and a zooming direction of the initial background image, and the sliding direction is opposite to the zooming direction; according to the position of the target object in the original image, superimposing an image of the target object onto the target background image to obtain a target image corresponding to the target frame; and generating a target video on the basis of the target image corresponding to the target frame.

摘要： In one implementation, a method of scene camera retargeting is performed by a head-mounted device (HMD) including one or more processors, non-transitory memory, a scene camera, and a display. The method includes capturing, using the scene camera, an image of a scene. The method includes determining, using the one or more processors, a depth of the scene. The method further includes transforming, using the one or more processors, the image of the scene based on the depth and a difference between a point-of-view of the scene camera and a point-of-view of a user. The method further includes displaying, on the display, the transformed image.

摘要： A method for tracking occluded objects includes encoding locations of a plurality of objects in an environment, determining a target object, receiving a first end point corresponding to a position of the target object before occlusion behind an occlusion object, distributing a hypothesis between both sides of the occlusion object during occlusion from a subsequent frame of the sequence of frames, receiving a second end point corresponding to a position of the target object after emerging from occlusion from another subsequent frame of the sequence of frames, and determining a trajectory of the target object when occluded by the occlusion object by performing inferences using a spatio-temporal probabilistic graph based on the current frame and the subsequent frames of the sequence of frames. The trajectory of the target object when occluded is used as a learning model for future target objects that are occluded by the occlusion object.

摘要： A system and method for hologram synthesis and processing capable of synthesizing holographic 3D data and displaying (or reconstructing) a full 3D image at high speed using a deep learning engine. The system synthesizes or generates a digital hologram from a light field refocus image input using the deep learning engine. That is, RGB-depth map data is acquired at high speed using the deep learning engine, such as a convolutional neural network (CNN), from real 360° multi-view color image information and the RGB-depth map data is used to produce hologram content. In addition, the system interlocks hologram data with user voice recognition and gesture recognition information to display the hologram data at a wide viewing angle and enables interaction with the user.
