Abstract: 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.

Abstract: A system comprises an aerial imaging platform configured to rise to a height above ground. An apparatus allows an entity to move the aerial platform in a desired direction. The aerial platform includes a camera positioned to capture images of the ground. The camera includes a position sensor. A user/entity may move the aerial platform over a region to be imaged. The system includes a device that may be carried by the user/entity. The device receives information about a region to be imaged and a field of vision of the camera, determines a first path, and provides information on the first path to the user/entity. As the user/entity moves the aerial platform along the first path, the device receives data from the camera position sensor and determines a second path. The user/entity may then move the aerial platform along the second path to capture unimaged areas of the region.

Abstract: 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.
