Abstract

The invention provides an initialization method, device and system of Simultaneous Localization and Mapping (SLAM) system, and an augmented reality (AR) control method, device, and system. The methodcomprises: determining the opposite height of a main camera according to the gravity direction, a main image shot by the main camera of the electronic device in the first direction and a standby imageshot by the standby camera of the electronic device at the same moment; determining a reference surface according to the gravity direction and the opposite height; and projecting the main image intoa reference surface, and determining three-dimensional coordinate information and / or depth information of at least one feature point in the main image. According to the embodiment of the invention, the initialization speed of the SLAM is improved, and the accuracy of the opposite height and the accuracy of map construction in the visual initialization process are also improved.

Description

technical field [0001] The present invention relates to computer image processing technology, in particular to a SLAM system initialization, AR control method, device and system. Background technique [0002] SLAM systems can be widely used in fields such as augmented reality, virtual reality, robotics, and autonomous driving. The SLAM system is used to obtain the attitude of the electronic device itself, the environment where the electronic device is located, and the position of the electronic device in the environment. [0003] When a user uses an electronic device, the SLAM system first initializes, obtains the initial motion state information of the electronic device and the initial environmental information of the environment where the electronic device is located, and then performs processing such as tracking the state of the electronic device and building a map of the scene in real time. The speed of SLAM system initialization affects the waiting time for users to us...
