Abstract: A display method comprises: acquiring multiple frames of images to be displayed, one frame of two adjacent frames of the images to be displayed being an image in an odd-numbered row, the other frame being an image in an even-numbered row, the resolution of the image in the odd-numbered row being M*(a*N), the resolution of the image in the even-numbered row being M*(a*N) or (M?1)*(a*N), and a being 1 or 2; and causing an odd-numbered display group to display the image in the odd-numbered row, and causing an even-numbered display group to display the image in the even-numbered row, the odd-numbered display group comprising M*(a*N) odd-numbered display units, the even-numbered display group comprising (M?1)*(a*N) even-numbered display units, the odd-numbered display unit in the i-th row comprising a first sub-pixel, a second sub-pixel, and a third sub-pixel in a pixel unit in the i-th row.

Abstract: The present disclosure provides an image compression method, including steps of: acquiring a human-eye fixation point on an original image, and determining a fixation region and a non-fixation region of the original image according to the human-eye fixation point; and compressing the non-fixation region, and generating a compressed image according to the fixation region and the compressed non-fixation region. The present disclosure also provides an image display method, an image compression apparatus, an image display apparatus, and a computer readable medium.

Abstract: A shooting method is provided, including: obtaining position information of a shooting object; planning a first circumnavigation route and a second circumnavigation route for surrounding shooting of the shooting object based on the position information; controlling a UAV to move along the first circumnavigation route and the second circumnavigation route respectively; and controlling the UAV to shoot the shooting object by a camera mounted on the UAV during movement to obtain multiple images of the shooting object. Images collected on the first circumnavigation route and images collected on the second circumnavigation route share homologous image points of the shooting object. The images are used to establish a three-dimensional model of the shooting object. Thus, the shooting efficiency of the UAVs is improved for shooting images for three-dimensional reconstruction.

Abstract: Methods and systems for generating a real-time map of a survey area are provided. The methods and systems may include or be configured to carry out the steps of determining, based on a desired map resolution, a flight path over the survey area for a movable object having at least one image capture device. The methods and systems further may include obtaining images of the survey area captured by the at least one image capture device as the movable object travels along the flight path, and processing the images to generate the real-time map of the survey area with the desired map resolution.

Abstract: Embodiments of the present disclosure provide a method for processing camera parameters. The method includes obtaining an environmental image set, the environmental image set including a first type image and two or more second type images, a direction of a light sensing element of the camera capturing the first type image being different from the direction of the light sensing element of the camera capturing the two or more second type images; calculating internal parameters of the camera based on a plurality of target object image points on the first type image and the two or more second type images in the environmental image set. The camera is mounted on an aircraft. The camera is configured to capture a plurality of environmental images of an environment below the aircraft. The calculated internal parameters of the camera include an image position of the principal point of the camera.
