Abstract

The invention relates to a method and device for testing a tracking position error. The method comprises the steps: selecting a first central point in a VR display scene; obtaining a first image according to the first central point; taking the first central point as a base point, rotating image obtaining equipment a preset angle, and selecting a second central point in the VR display scene; obtaining a second image according to the second central point; and determining the tracking position error according to the first image and the second image. According to the technical scheme of the invention, the first image is obtained according to the first central point, and the second image is obtained according to the second central point, and the tracking point error is determined according to the first and second images, thereby ironing out the defects in the prior art that the cost is high and the precision is low when additional equipment is added for obtaining the tracking position error. The method achieves the technical effects that the method is precise, is high in efficiency, and is low in cost.
