摘要： An imaging system that includes a camera mourned on an aerial platform, for example a balloon, allows a user to increase the longevity of the camera's battery by remote control. A user may capture imagery at a time scale of interest and desired power consumption by adjusting parameters for image capture by the camera. A user may adjust a time to capture an image, a time to capture a video, or a number of cycles per time period to capture one or more images as the aerial platform moves in a region of interest to change power consumption for imaging. The system also provides imaging alignment to account for unwanted movement of the aerial platform when moved in the region of interest. Additionally, a mounting device is provided that is simple and inexpensive, and that allows a camera to remain positioned in a desired position relative to the ground.

摘要： A gateway that may be implemented in a local network and that communicates with a cloud network to provide efficient services in a weakly connected setting is disclosed. The gateway may be configured to enable services that efficiently utilize resources in both of the gateway and the cloud network, and provide a desired quality of service while operating in a weakly connected setting. The gateway may provide data collection and processing, local network services, and enable cloud services that utilize data collected and processed by the gateway. The local network may include one or more sensors and/or video cameras that provide data to the gateway. In a further implementation, the gateway may determine an allocation of one or more tasks of a service between the gateway and a cloud network by determining the allocation of the one or more service tasks based on desired service latency.

摘要： An apparatus for generating precision maps of an area is disclosed. The apparatus receives sensor data, where the sensor data includes sensor readings each indicating a level of a parameter in one of a plurality of first portions of an area, and video data representing an aerial view of the area. The sensor data may be received from sensors that are each deployed in one of the first portions of the area. The video data may be received from an aerial vehicle. An orthomosaic may be generated from the video data, and the orthomosaic and the sensor data used to generate a predication model. The prediction model may then be used to extrapolate the sensor data to determine a level of the parameter in each of a plurality of second portions of the area. A precision map of the area may be generated using the extrapolated sensor readings.

摘要： Embodiments that relate to determining gaze locations are disclosed. In one embodiment a method includes shining light along an outbound light path to the eyes of the user wearing glasses. Upon detecting the glasses, the light is dynamically polarized in a polarization pattern that switches between a random polarization phase and a single polarization phase, wherein the random polarization phase includes a first polarization along an outbound light path and a second polarization orthogonal to the first polarization along a reflected light path. The single polarization phase has a single polarization. During the random polarization phases, glares reflected from the glasses are filtered out and pupil images are captured. Glint images are captured during the single polarization phase. Based on pupil characteristics and glint characteristics, gaze locations are repeatedly detected.

摘要： The claimed subject matter provides for systems and/or methods for identification of instances of an object of interest in 2D images by creating a database of 3D curve models of each desired instance and comparing an image of an object of interest against such 3D curve models of instances. The present application describes identifying and verifying the make and model of a car from a possibly single image—after the models have been populated with training data of test images of many makes and models of cars. In one embodiment, an identification system may be constructed by generating a 3D curve model by back-projecting edge points onto a visual hull reconstruction from silhouettes of an instance. The system and methods employ chamfer distance and orientation distance provides reasonable verification performance, as well as an appearance model for the taillights of the car to increase the robustness of the system.
