Embodiment Construction
[0037] Now in conjunction with the accompanying drawings, the preferred embodiments of the present invention will be described in detail.
[0038] Such as figure 2 Shown is a flowchart of a method 200 for generating a field of view picture image according to an embodiment of the present invention. Step 201 first receives the resolution of the field of view picture, the panoramic video image, and the current angle of view attitude parameter, and calculates each pixel in the field of view picture image according to the resolution of the field of view picture, the current angle of view attitude parameter, and the format of the panoramic video image. The corresponding coordinates in the panoramic video image; wherein, the panoramic video image may include the data information and format of the panoramic video image. In a specific implementation manner, the resolution of the field of view picture may be a hardware property of the screen of the field of view picture, and the fixed...

The invention relates to a field view image generation method. The method comprises the steps of receiving a resolution, a current angle of view gesture parameter and a panoramic video image of a field view image, and calculating coordinates of each pixel of the field view in the panoramic video image according to the resolution, the current angle of view gesture parameter and the panoramic video image of the field view image; and extracting a value of an interpolation point desired by the pixel of the field view image according to the coordinates in the panoramic video image so as to perform interpolation calculation to generate a field view image. Through adoption of the field view image generation method and apparatus, the load and power consumption of a processor are lowered, and the bandwidth resources are saved. The invention further provides a field view image generation apparatus. Coordinate conversion and interpolation calculation are performed on each pixel by using a hardware circuit, the power consumption is low, further, high image quality and low display delay are realized. The field view image generation apparatus realized by the hardware can directly output the field view image to a display device, and can save bandwidth resources and lower display delay effectively.
Description
technical field [0001] The invention relates to the field of digital video processing, in particular to a method and device for generating a field of view picture image. Background technique [0002] Panoramic transformation is a process of generating the user's subjective field of view from the input panoramic video image according to the angle of view and pose parameters. It is mainly used in VR devices. Panoramic video images are a type of video images that include panorama information of 360 degrees horizontally and 180 degrees vertically, and currently mainly include spherical panorama and cube panorama formats. Viewing panoramic video images from a subjective perspective through a VR device can provide users with an immersive experience. At the same time, this type of application also puts forward higher requirements on the image rendering quality, frame rate and display delay of VR devices. [0003] The existing panoramic transformation basically adopts the solution...
