Publication number: 20240176353Abstract: The present invention provides a method of alerting to stationary objects for vehicle. When a vehicle moves at a first speed, an optical scanning device, an infrared image extraction device, and an image extraction device extract a first optical scanning image, a first infrared image, and a first ambient image of the ambiance on one side of the vehicle. According to the fusion algorithm and the optical flow method, the first obstacle information of the first obstacle in the first image will be given. According to the location information of the first obstacle, the vehicle computer judges and generates an alert message when the relative distance is smaller than a distance threshold value and the obstacle volume is greater than a volume threshold value.Type: ApplicationFiled: July 6, 2023Publication date: May 30, 2024Inventors: TSUNG-HAN LEE, JINN-FENG JIANG, SHIH-CHUN HSU, TSU-KUN CHANG, CHENG-TAI LEI, HUNG-YUAN WEI

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
