Abstract: A method for moving an optical device relative to an image sensor to focus an image includes receiving a current image acquired by the image sensor when the optical device is at a current position relative to the image sensor, obtaining a current contrast value of the current image and a current contrast variation rate at the current position, determining whether the current contrast variation rate meets a first threshold criterion, moving the optical device from the current position to a next position in accordance with the determination result, and repeating the aforementioned operations until a next contrast variation rate for a next image meets a second threshold criterion. The next image is acquired when the optical device is at the next position.

Abstract: An image processing method includes obtaining an acquired image captured by an image acquisition device and obtaining vibration information associated with the acquired image and generated while the image acquisition device capturing the acquired image. The vibration information includes an angle of vibration. The method further includes performing a distortion correction to the acquired image to obtain a distortion-corrected image based upon the vibration information and a preset distortion correction parameter, and determining a target image from the distortion-corrected image based upon the vibration information.

Abstract: A system for adapting various writing speeds of storage devices and methods for making and using same are provided. A recording device maintains a data buffer with a buffer size. Data recorded by the recording device with a selected recording bitrate is stored into the data buffer of the recording device. The recorded data is written from the data buffer into a selected storage device that is attached onto the recording device. An amount of recorded data stored in the data buffer is compared with two or more sets of thresholds, and the recording bitrate of the recording device can be adjusted, as needed, in response to the results of the comparison. By adjusting the recording bitrate, the recording device advantageously can accommodate storage devices with various speeds while maintaining the quality of the recorded data and maximizing the capacity of the storage device.

Abstract: The present disclose provides a Bayer color filter array based high dynamic range video recording method and device. The method includes configuring different photosensitive times for exposure according to odd-numbered dual columns and even-numbered dual columns, and obtaining an image frame with different exposure values of the odd-numbered dual columns and even-numbered dual columns; decomposing the image frame into an underexposure image frame and an overexposure image frame, where underexposure dual columns and missing dual columns are alternatingly distributed in the underexposure image frame, and overexposure dual columns and missing dual columns are alternatingly distributed in the overexposure image frame. The method also includes acquiring recovered pixel values of pixel points of the missing dual columns in the underexposure image frame and the overexposure image frame; and merging the overexposure image frame and the underexposure image frame to obtain a high dynamic range frame.

Abstract: The present invention provides methods, systems, and apparatus for generating panoramic aerial images. An image capturing device is coupled to an unmanned aerial vehicle (UAVs) via a carrier configured to allow the image capturing device to rotate around one, two, or three axes relative to the UAV. To generate a panoramic image, the UAV is brought to hover or remain substantially stationary near a predetermined location. While the UAV is hovering over the predetermined position, the carrier causes the image capturing device to rotate around a first axis while stabilizing the image capturing device with respect to at least a second axis. As the image capturing device rotates, it captures a plurality of overlapping images. The plurality of images can be processed entirely onboard the UAV to generate a panoramic image without transmitting the plurality of images to a remote device.

Abstract: A system for focusing an imaging device according to a focal distance setting and methods for making and using same. The focal distance setting can be an infinite focal distance setting for objects that are far away from the imaging device. Focusing of the imaging device can be triggered by activation of a button for “one-touch” rapid focusing. The focusing, for example, can be triggered at a terminal that is distal from the imaging device through an app and suitable user interface. The focal distance setting can be determined by interaction via the app, which can present a prompt to direct the imaging device to an object at a suitable distance. Once determined, the focal distance setting can be stored and later retrieved for rapid focusing. The present system and methods advantageously can be used aboard a mobile platform such as an unmanned aerial vehicle.

Abstract: A method for moving an optical device of an imaging device includes one or more depth sensors acquiring one or more depth measurements within a predefined spatial coordinate system. Each of the one or more depth measurements indicates a distance from the imaging device to an object within the predefined spatial coordinate system. The method further includes one or more orientation sensors determining orientation information of the imaging device within the predefined spatial coordinate system, estimating an object distance between the imaging device and the object based on the one or more depth measurements and the orientation information, and moving the optical device from a first position to a second position according to the object distance and a focal length of the optical device.
