A representative method includes receiving a request to land a movable object and, in response to the request, identifying a target landing area on a landing surface based on at least one image of the landing surface obtained by the movable object. The method can further include directing the movable object to land at the target landing area.

Abstract: A method of distance measuring includes obtaining a depth map and a stereo pair of images of a scene of interest, and enhancing a precision of the depth map based on disparity values of corresponding points between the images. The images have a higher resolution than the depth map. Enhancing the precision of the depth map includes determining the disparity values by optimizing an energy function of the images and replacing low precision values of the depth map with corresponding high precision values based on the disparity values.

Abstract: A method of controlling flight of an unmanned aerial vehicle (UAV) includes collecting, while the UAV traverses a flight path, a first set of images corresponding to different fields of view of an environment around the UAV using multiple image capture devices. Each of the multiple image capture devices has one of the different fields of view. The method further includes extracting a first set of feature points from the first set of images, controlling the UAV to traverse a return path, and while the UAV traverses the return path, collecting a second set of images corresponding to the different fields of view using the multiple image capture devices and comparing the first set of feature points with a second set of feature points extracted from the second set of images.

Abstract: A method for determining position of a target includes determining at least two measurement points of the target, obtaining vector data of at least two direction vectors based on an imaging position of the target on an imaging system and parameter data of the imaging system, and determining a distance between the target and the imaging system according to the vector data and a current vertical height of the imaging system. Each of the at least two direction vectors is a vector from the imaging system to a corresponding one of the at least two measurement points.

Abstract: An apparatus for performing simultaneous localization and mapping (SLAM) with an imaging device having at least two lenses includes an Inertial Measurement Unit (IMU) configured to measure rotations of a second stereoscopic frame acquired at a second time point in related to a first stereoscopic frame at a first time point, and a controller configured to acquire the first stereoscopic frame and the second stereoscopic frame, acquire rotation data of the second stereoscopic frame from said IMU, and match said first and second stereoscopic frames by combining the rotation data with the first and second stereoscopic frames. Said first stereoscopic frame overlaps with said second stereoscopic frame by a predetermined percentage.

Abstract: A system for establishing a baseline of a stereoscopic imaging device having a microlens array and methods for making and using the same. The system acquires an object distance between the microlens array and an object of interest and selects first and second lenses from the microlens array based upon the acquired object distance. The system likewise can perform simultaneous localization and mapping (SLAM) with the imaging device. In one embodiment, the system can acquire first and second stereoscopic frames with the microlens array. The system thereby can measure rotations of the second stereoscopic frame with an Inertial Measurement Unit (IMU) and match the first and second stereoscopic frames by combining the rotation data with the first and second stereoscopic frames. The system thereby can enable SLAM systems to perform more accurately and more practically in various indoor and/or outdoor environments.
