Patent number: 12646158Abstract: Provided are a device and a method for detecting a wildfire. The wildfire detecting device may include: an image data acquisition module acquiring image data captured by a shooting device; an image data storage module storing the image data acquired through the image data acquisition module in a storage space; a wildfire detection module performing wildfire detection by using a deformable convolution based deep learning model to which smoke characteristics widely diffused are reflected by dynamically adjusting a filter position by using a learnable offset from the image data; and a wildfire direction and position estimation module estimating a direction and a position of the wildfire with respect to a case where it is determined that the wildfire occurs by the wildfire detection module.Type: GrantFiled: August 23, 2023Date of Patent: June 2, 2026Assignee: ALCHERA INC.Inventors: Jisu Kim, Youngseo Cha, Hee Chan Park, Yewon Jun, Minkook Cho

Patent number: 11127218Abstract: Disclosed herein is a method for creating augmented reality content. The method for creating augmented reality content includes: extracting a target area, to which augmented reality content will be applied, from an object included in an image; providing a template for the creation of the augmented reality content that will be applied to the extracted target area; when a user inputs user content via the template, creating the augmented reality content by using the user content and the metadata of the target area; and performing rendering so that the created augmented reality content is applied to the target area of the image.Type: GrantFiled: December 30, 2019Date of Patent: September 21, 2021Assignee: ALCHERA INC.Inventors: Sugang Ju, Jung Woo Chang, Young Kyoo Hwang, Jung Bae Kim
