1. A data transmission method for a virtual reality system, the data transmission method comprising:
capturing a portion of an image to be transmitted in a preset area by performing image sampling on the preset area of the image to be transmitted with a preset first resolution, a preset first field angle and a preset first refresh rate to obtain a first image, and compressing a portion of the image to be transmitted in a display area by performing image sampling on the display area of the image to be transmitted with a preset second resolution, a preset second field angle and a preset second refresh rate to obtain a second image, wherein the preset area is a portion of the display area;
transmitting the first image and the second image to a virtual reality apparatus in a certain order;
receiving the first image and the second image by the virtual reality apparatus;
stretching the second image by the virtual reality apparatus, and merging the first image with a stretched second image by the virtual reality apparatus to obtain an image to be displayed; and
displaying the image to be displayed by the virtual reality apparatus,
wherein the first resolution and the second resolution are equal to each other, the first field angle is less than the second field angle, and the first refresh rate is greater than or equal to the second refresh rate.
