It may even appear that the self in the screen has been walking south, and sees the pictures of scenic spots appearing from north to south, but in fact the user is really facing the north at this time, and the user's back is hot, while in the screen What I see is that I am facing the south, this kind of user experience makes the user feel very contradictory

Embodiment Construction
[0026] figure 1 Shown is a 360 panoramic camera, which can be used to capture 360-degree panoramic videos and movies. The camera is spherical and surrounded by cameras. When starting 360-degree panoramic video shooting, all cameras start shooting at the same time from different directions and angles. Before the image is processed, the pictures taken by different cameras are repeated. In the later video processing, it is necessary to select and splicing the shooting content of different cameras, and mark the video pictures viewed from different directions and angles. The direction parameters are stored in the video file for Used later for orientation comparison and calibration. The orientation parameters stored in the video file include the orientation parameter and the included angle with the horizontal plane. The orientation parameter is used to identify the user’s east-west, north, south, and north directions, and the included angle with the horizontal plane is used to indi...

The invention provides a direction synchronizing method of head-mounted equipment. The direction of a picture in a video and the direction of a user can be maintained to be the same, so that the realistic effect of watching the video when the user wears a helmet, and the user experience is improved. That the direction of the picture in the video and the direction of the user are the same is realized, and development and design are carried out in three aspects mainly: firstly, after the picture of the video is shot, the direction parameter of the picture is added when the picture is integrally designed, and the parameter can be extracted to be analyzed; secondly, the head-mounted equipment comprises a compass chip and a gyroscope, the direction parameter of the head-mounted equipment can be analyzed, and the direction parameter comprises two parameters such as orientation and an included angle of the head-mounted equipment and the horizontal plane; and thirdly, calibration and unification of the direction of the video and the direction of the user helmet are completed by using the means such as an APP of a mobile phone according to a set flow path.
Description
technical field [0001] The present invention is applicable to virtual reality VR and augmented reality AR helmets, including but not limited to the field of head-mounted devices of VR and AR helmets. Background technique [0002] Recently, the development of virtual reality VR (Virtual Reality) and augmented reality AR (Augmented Reality) is in full swing. Wearing VR and AR helmets can not only watch movies with IMAX effects and 3D effects, but even watch 360-degree panoramic pictures, 360-degree panoramic videos and 360-degree panoramic movies. [0003] Whether it is a 360-degree panorama shot with a single camera rotation, or an omni-directional multi-camera camera (attached figure 1 ) for 360-degree panoramic videos and movies. Before wearing VR and AR helmets to watch 360-degree panoramic pictures, videos and movies, the direction of the helmets needs to be corrected and synchronized. The current calibration method is to first place the phone horizontally on the table...
