Abstract: A method using a UWB for precisely positioning in an environment without a positioning infrastructure is provided. The method, when positioning objects of swarm objects in a free space, etc., calculates an object position of each object through cooperation with objects existing surrounding. In this state, positioning is simply performed without a specific anchor by defining objects as anchors in a UWB in accordance with an embodiment. In particular, cooperative positioning is quickly performed by reducing position errors of objects in accordance with pull-push relationships based on UWB TWR. Therefore, when a specific mission is performed in an environment in which a positioning infrastructure does not exist or is lost, such as a flight space, positioning is performed in the UWB-based cooperative positioning method described above, whereby precise positioning suitable for these environments is provided.

Abstract: Proposed is a method of determining a location for swarm flight using UWB, the method including: computing a reference location from GPS information in a case where the location is measured; sending out a pulling signal, preset according to a two-way ranging format, according to slave ranging scheduling corresponding to each formation, and receiving a pushing signal from a neighboring flight vehicle and performing ranging; computing a relative location in the formation on a master-slave basis from a ranged pull-push relationship using TWR time information, and computing the relative location in the formation on a slave-slave basis using a received signal strength indicator and time of arrival; generating a fingerprint map in a manner that varies with each formation, using all the computed relative locations in the formation on the master-slave basis; and computing the location of the swarm flight vehicle using the generated fingerprint map.

Abstract: An image processing method includes receiving a first image rendered by a graphics processing unit (GPU) from the GPU, comparing the first image with a second image rendered by the GPU before the first image, and controlling a rendering frequency of the GPU based on a result of comparing the first image with the second image.

Abstract: A method for processing images includes displaying a first image rendered by a graphic processing unit on a display panel, collecting at least one temperature data of at least one measurement point of the display panel or a host device, and adaptively adjusting an updating frequency of a second image based on the collected at least one temperature data. The second image is to be displayed on the display panel subsequent to the first image.

Abstract: A machine moves shoe strobels to a camera or scanner where images of the strobels are captured. Using the images, a computing device instructs a printer how to mark guidelines within a threshold distance of each other on the strobels that signify strobel sewing lines for different shoes models and shoe sizes. Cross-sectional lines may also be printed on the strobels to aid in error-checking guideline marking. Unmarked strobels are stacked in a loading compartment, sometimes in pairs—e.g., right and left shoe strobels. The unmarked strobels are transferred to a conveyor that brings the strobels to the camera or scanner and the printer. After guidelines and/or cross-sectional lines are added to the strobels, the marked strobels are stacked in a compartments housing other marked strobels.
