Abstract: A three-dimensional (3D) reconstruction system based on aerial photography includes an unmanned aerial vehicle (UAV), a ground station, and a cloud server. The ground station is configured to determine an aerial photography parameter for indicating an aerial photography state of the UAV based on a user operation and transmit the aerial photography parameter to the UAV. The UAV is configured to receive the aerial photography parameter transmitted by the ground station; fly based on the aerial photography parameter and control an imaging device carried by the UAV to acquire aerial images during a flight; and transmit the aerial images to the cloud server. The cloud server is configured to receive the aerial images and generate a 3D model of a target area based on the aerial images.

Abstract: A vision-based positioning method includes extracting first features from a first image and second features from a second image, determining initial matching pairs according to the first features and the second features, extracting satisfying matching pairs that meet a requirement from the initial matching pairs according to an affine transformation model, and determining a position-attitude change according to the satisfying matching pairs. The first image and the second image are obtained by a vision sensor carried by an aerial vehicle. The position-attitude change indicates a change from a position-attitude of the vehicle when the vision sensor captures the first image to a position-attitude of the vehicle when the vision sensor captures the second image.

Abstract: A visual simulation system includes a non-transitory computer-readable memory that stores computer-executable instructions and one or more processors individually or collectively configured to access the memory. The one or more processors are individually or collectively configured to execute the computer-executable instructions to generate visual data of a virtual environment obtained by a simulated visual sensor associated with a simulated movable object, obtain one or more parameters of a physical visual sensor corresponding to the simulated visual sensor, the one or more parameters comprising a noise-related parameter, and transform the generated visual data to simulate an effect of the one or more parameters.

Abstract: Methods and associated systems and apparatus for generating a three- dimensional (3D) flight path for a moveable platform such as an unmanned aerial vehicle (UAV) are disclosed herein. The method includes receiving a set of 3D information associated with a virtual reality environment and receiving a plurality of virtual locations in the virtual reality environment. For individual virtual locations, the system receives a corresponding action item. The system then generates a 3D path based on at least one of the set of 3D information, the plurality of virtual locations, and the plurality of action items. The system then generates a set of images associated with the 3D path and then visually presents the same to an operator via a virtual reality device. The system enables the operator to adjust the 3D path via the virtual reality device.
