Publication number: 20240169582Abstract: A method for scenario triggering and interaction is disclosed. One or more camera devices (110) are used to monitor a target object (142) in a scene (140). A target object vector (143a) is generated from captured images of each camera device (110) to represent a line of sight from the camera device (110) to the target object (142). A target object position (129) in the scene (140) is then determined from an intersection of the target object vectors (143a). The target object position (129) is compared with a task triggering region (144) in the scene (140) to trigger a pre-determined task when the target object (142) is within or around the task triggering region (144). For example, the target object (142) may be a human user and augmented reality contents are presented to the human user when the human user is detected to be within or around the task triggering region (144).Type: ApplicationFiled: March 7, 2022Publication date: May 23, 2024Applicant: HANGZHOU TARO POSITIONING TECHNOLOGY CO., LTD.Inventor: Hao Qian
