Problems solved by technology

[0005] (1) The preview content sent by the panoramic camera to the mobile phone is reduced from a relatively large resolution, so it will inevitably cause a loss of precision, and the details of the preview are not clear
[0006] (2) Zooming action is a very resource-consuming action, which will increase the consumption of DDR bandwidth and power consumption

Embodiment Construction

[0040] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0041] The steps shown in the flowcharts of the figures may be performed in a computer system, such as a set of computer-executable instructions. Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0042] In the prior art, after panorama content (for example, panorama picture and panorama video, etc.) is obtained, the resolution of the panorama content is reduced to reduce the bit rate of the panorama content, so as to obtain panorama content for pre...

Abstract

The invention discloses a method and apparatus for previewing panoramic contents. The method comprises the following steps: obtaining a panoramic image, and adhering the panoramic image on the surface of a predetermined three-dimensional geometric body to obtain a panoramic display body; intercepting an image within a viewer visual field range from the panoramic display body according to visual field direction information received from a display device; and encoding the intercepted image within the viewer visual field range to obtain preview data, and transmitting the preview data to the display device, so that the preview data displays the intercepted image within the viewer visual field range, and thus a viewer previews the panoramic contents. By adoption of the method and apparatus disclosed by the invention, zooming of the panoramic image is not required, the original precision of the sensor input image is not lost, the display effect is clearer, moreover, the increase of excessive DDR bandwidth consumption and power consumption caused by image zooming is avoided, meanwhile only the image within the visual field is focused, thereby better meeting the mode of the human body to observe the outside, and the transmission of redundant data is reduced, so the network bandwidth is effectively used.

Description

technical field [0001] The invention relates to virtual reality technology, in particular to a method and device for previewing panoramic content. Background technique [0002] With the emergence of panoramic cameras and the popularization of the concept of the Internet of Things, the interconnection between mobile phones and panoramic cameras has become inevitable. Through the mobile phone, the panoramic camera can be controlled, and the panoramic pictures and panoramic videos taken by the panoramic camera can also be previewed. [0003] At present, the resolution of the panoramic video recorded by the panoramic camera is often above 3K, and the bit rate is often above 20Mbps. When such a code rate is transmitted through the wifi network, it will generate a large load on the wifi network, and it is easy to cause delays, blurred screens, freezes and other phenomena. Therefore, in order to have a better preview effect, when the panoramic video is recorded to the SD card at ...
