    Abstract: In the method, a first pair of coordinates of a maximum temperature point in an image sensed by an infrared camera is acquired, where the image is an image captured by the infrared camera. A rotation angle of a gimbal equipped with the infrared camera is then determined according to the first pair of coordinates of the maximum temperature point and a pair of coordinates of a target position in the image. The gimbal is then controlled to rotate according to the determined rotation angle, so as to adjust the maximum temperature point in the image captured by the infrared camera to be located at the target position.

    Abstract: A method for identifying a photovoltaic panel includes: acquiring a grayscale image of an infrared image captured by a camera mounted on a UAV, the grayscale image including an image of a photovoltaic panel; performing edge extraction processing on an image in the grayscale image to obtain a monochrome image including a plurality of horizontal lines and a plurality of vertical lines, the horizontal lines being lines in a first direction, an average length of the lines in the first direction being greater than a preset length, the vertical lines being lines in a second direction, and an average length of the lines in the second direction being less than the preset length; and identifying the photovoltaic panel in the monochrome image based on a relative positional relationship between the horizontal lines and the vertical lines in the monochrome image.

    Abstract: An image control method includes receiving, by a camera, a photographing instruction transmitted by an image display device. The camera includes a first image sensor and a second image sensor. The method further includes controlling the second image sensor to perform photographing according to the photographing instruction to obtain a display code stream and transmitting the display code stream to the image display device. The photographing instruction is used to instruct the second image sensor to photograph for a partial area of a first image using a focal length to obtain a second image. The first image is obtained by the first image sensor and displayed in a main display window of the image display device. The display code stream includes a code stream corresponding to the second image sensor.

    Abstract: A control device includes a touchscreen and one or more processors. The touchscreen is configured to display an image captured by an imaging device supported by a movable object or a carrier coupled to the movable object, and receive a user input indicative of selection of a position on the touchscreen to display a selected target of the image and selection of a zoom factor for zooming in or out of the selected target. The one or more processors are configured to generate control data based on information about the user input. The control data includes instructions for the imaging device, the carrier, or the movable object to automatically control an attitude of the imaging device for positioning the selected target at or near the selected position on the touchscreen and a zoom level of the imaging device according to the user selected zoom factor.

    Abstract: An image fusion method includes acquiring a trigger signal for flat-field correction, controlling a first image acquisition device to start a flat-field correction function to perform a flat-field correction process on the first image acquisition device according to the trigger signal for the flat-field correction, and obtaining a fused image in the flat-field correction process according to an infrared image acquired by the first image acquisition device and a visible light image acquired by a second image acquisition device. The first image acquisition device does not output infrared images during the flat-field correction process.

    Abstract: An image presentation method includes obtaining a first image and a second image having same contents; size-processing the first image according to at least one of a target resolution, an aspect ratio of the first image, or an aspect ratio of the second image to generate a size-processed first image having the target resolution; generating a presenting image at least by combining the size-processed first image and the second image; and encoding the presenting image in a code stream and transmitting the encoded image to the display device that requires the preset resolution for display. The first and second images include a visible-light image and an infrared image. The presenting image has a preset resolution no less than a sum of the target resolution and a resolution of the second image. The size-processed first image and the second image are arranged in the presenting image without partially blocking each other.
