Publication number: 20240068783Abstract: A method to detect, identify and determine the position of laser points from infrared laser emitters in a firearm training simulation system. The method consists of two steps. This first step combines some common tools such as a camera with a filter switcher and edge and corner detecting algorithms in image processing to provide a fast automatic screen calibrating method. The second step is to detect laser point objects in each frame continuously captured by the camera, and then further process these objects to identify laser shots, filter out noisy objects, and eventually detect simulated shots from different laser emitters and determine the final mapped position of the shot.Type: ApplicationFiled: July 25, 2023Publication date: February 29, 2024Applicant: VIETTEL GROUPInventors: Anh Tuan Vu, Duc Thanh Nguyen, Van Duc Ha, Kim Duc Hoang, Thanh Nhon Nguyen, Anh Tra Duong, Tran Nam Nguyen
