Distributed augmented reality positioning terminal, positioning server and positioning system

Abstract

The invention provides a distributed augmented reality positioning terminal, a positioning server and a positioning system, and the distributed augmented reality positioning system comprises a positioning terminal and a positioning server which can carry out data transmission. The positioning terminal comprises a head-mounted device, and the head-mounted device comprises a binocular inertial navigation sensing module used for acquiring a scene image and providing IMU data; a display module which is used for receiving and displaying the fused image; and portable processing equipment which is used for calculating the rotation R and the position T of the camera according to the scene image and the IMU data. The positioning server comprises a storage module used for storing a prefabricated model and a rotation R and a position t of a scene of the prefabricated model; and a fusion module which is used for generating a fusion image according to the rotation R and the position T of the cameraand the rotation R and the position t of the prefabricated model and the scene thereof. According to the invention, the attitude and position relative to the scene can be measured, the depth distanceinformation relative to the object can be measured, and the perception information amount of the scene is larger.

Description

technical field [0001] The invention belongs to the technical field of augmented reality positioning, and in particular relates to a distributed augmented reality positioning terminal, a positioning server and a positioning system. Background technique [0002] The mainstream portable augmented reality positioning solutions currently on the market include head-mounted integrated devices represented by HoloLens, and split devices represented by Magicleap. HoloLens embeds data acquisition, data processing, and fusion display modules into the head-mounted device. While ensuring positioning accuracy, it minimizes the weight of the device, but at the same time it also brings problems such as severe heat generation and short standby time. . Magicleap has improved the above problems very well, and placed the data processing and fusion rendering module on the split microprocessor to achieve a higher positioning effect. The above two devices have great advantages in audio-visual en...

Problems solved by technology

The above two devices have great advantages in audio-visual entertainment applications, but in industrial applications, due to the problems of processor performance, heat dissipation performance, and operating system compatibility, it is difficult to get real applications

[0003] like figure 1 As shown, for industrial-grade augmented reality devices, HTC VIVE meets the requirements of most scenarios, but strictly speaking, HTC VIVE is not an independent device. In order to display complex virtual scenes, a high-end computer is required, and its application process There will be the following problems: (1) The secondary development of VIVE requires a larger site due to the positioning of the base station, which is convenient for debugging and good perception; (2) It can only be applied in a specified space
