Publication number: 20240121373Abstract: Disclosed are an image display method and a 3d display system. The method is adapted to the 3d display system including a 3d display device and includes the following steps. A first image and a second image are obtained by splitting an input image according to a 3d image format. Whether the input image is a 3D format image complying with the 3D image format is determined through a stereo matching processing performed on the first image and the second image. An image interweaving process is enabled to be performed on the input image to generate an interweaving image in response to determining that the input image is the 3D format image complying with the 3D image format, and the interweaving image is displayed via the 3D display device.Type: ApplicationFiled: May 10, 2023Publication date: April 11, 2024Applicant: Acer IncorporatedInventors: Kai-Hsiang Lin, Hung-Chun Chou, Wen-Cheng Hsu, Shih-Hao Lin, Chih-Haw Tan

Patent number: 11636690Abstract: The disclosure provides an environment perception device and method of a mobile vehicle. The environment perception device includes a camera module, a LiDAR module, a database and a processing circuit. The camera module photographs a field near the mobile vehicle to generate a three-dimensional (3D) image frame. The LiDAR module scans the field to generate a 3D scanned frame. The processing circuit fuses the 3D image frame and the 3D scanned frame to generate 3D object information. The processing circuit compares the 3D object information with a 3D map in the database to determine whether an object is a static object. The processing circuit performs an analysis and calculation on the 3D object information to obtain movement characteristics of the object when the object is not the static object, and skips the analysis and calculation on the 3D object information when the object is the static object.Type: GrantFiled: March 8, 2021Date of Patent: April 25, 2023Assignee: Metal Industries Research & Development CentreInventors: Tsung Han Lee, Jinn-Feng Jiang, Shih-Chun Hsu, Tsu-Kun Chang, Hung-Yuan Wei, Cheng-Tai Lei

Patent number: 11232689Abstract: The present invention provides a smoke detection method with visual depth, which uses an image camera and a depth camera to extract surrounding images and surrounding depth information. A vehicle is used to patrol an area, such as the area of a processing factory, for receiving the surrounding environment information and detecting existence of burning objects or smoke. Then a processor adopting the clustering algorithm is used to estimate the smoke distribution or the location of fire source of burning objects, and uses an alarm to provide alarm information. Thereby, the rescue crew can prepare in advance and respond immediately. By providing the correct information to the firemen in the fire scenes, the time to control the fire can be shortened and the time for evacuation can be increased.Type: GrantFiled: January 3, 2020Date of Patent: January 25, 2022Assignee: Metal Industries Research & Development CentreInventors: Tsung-Han Lee, Jinn-Feng Jiang, Shih-Chun Hsu, Tsu-Kun Chang, Hung-Yuan Wei

Patent number: 9963069Abstract: The present disclosure provides an alarm method for reversing a vehicle, in particular for a land vehicle, by sensing obstacles using structured light. When a vehicle reverses, the structured-light projecting module installed on the rear side of the vehicle projects structured light continuously, A plurality of light pattern messages are reflected to the structured-light camera unit. Then the height of and the distance to the obstacle are calculated. According to the height of the obstacle, whether the obstacle may influence the vehicle will be judged. If so, sounds will be emitted for reminding the driver according to the distance to the obstacle and the alarm distance information. Thereby, the reversing safety can be improved.Type: GrantFiled: November 16, 2016Date of Patent: May 8, 2018Assignee: Metal Industries Research & Development CentreInventors: Jinn-Feng Jiang, Shih-Chun Hsu, Hung-Yuan Wei, Tsung-Han Lee, Tsu-Kun Chang, Kuei-Shu Hsu, Chia-Sui Wang
