Embodiment Construction

[0032] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0033] The present invention provides a target detection method for an augmented reality system that can be used in daily life. The system can quickly and efficiently find the objects needed by users from complex real environments, provide convenience for users' daily life, and help users Improve work efficiency. This system directly uses the integrated RGB camera on the AR helmet to capture real-time image information in the real environment, performs target detection locally, and intuitively displays the detection results on the AR helmet in the form of a detection frame. Users can use the system to quickly, accurately and intuitively find the objects they need from complex environments, thus improving the work and life of users.

[0034] In order to solve the above problems, this system directly uses the RGB camera integrated on the NED+GlassX2 series ...

Abstract

The invention discloses a target detection method for an augmented reality system. The method enables a user to visually observe a real environment through optical transmission type AR glasses in a mode of combining AR glasses with a target detection neural network, and does not need to compare an image in a display with the real environment for operation in the real environment like a cellphone.And the use complexity of the user is reduced. And meanwhile, the fusion difficulty between AR display and the real world is simplified by utilizing a calibration method, the calculation complexity isreduced to a certain extent, and the time delay is reduced, so that better real-time AR experience is brought to a user.

Description

technical field [0001] The invention belongs to the technical field of AR augmented reality, and in particular relates to a target detection method of an augmented reality system. Background technique [0002] At present, some research proposes to use the target detection network for the AR detection method of video transmission. They use handheld mobile devices such as mobile phones to shoot the environment, and use a simplified SSD target detection network to perform target detection on the images captured by the mobile phone. Then, they directly frame the target object on the screen of the mobile phone to complete the target detection. The method of directly using a device such as a mobile phone to shoot the environment and display the detection frame directly on the mobile phone cannot bring users an intuitive AR experience. Users need to observe the mobile phone screen first during use, confirm the position of the target object from the mobile phone screen and compare...
