Abstract

The invention provides a depth-of-field setting optimization method and device based on image scale. The device comprises a test unit, an observation unit, an image unit and a processing unit. The test unit comprises a virtual reality helmet to be set and a fixation structure. The virtual reality helmet to be set comprises a display screen. The fixation structure comprises a clamping tool and a limit mechanism. The clamping tool can be opened to allow the virtual reality helmet to be put in. Compared with the prior art, the method and device can effectively and simply solve the problem of depth-of-field measurement through combination of the test unit, the observation unit, the image unit and the processing unit. The observation unit is driven to move along an eyepiece track by a motor, so that observation can be realized from multiple angles, and setting of multiple observation points can be realized conveniently.

Description

technical field [0001] The present invention relates to the field of virtual reality, and more specifically, relates to a method and device for setting optimization of depth of field based on image scale. Background technique [0002] Distortion lenses are used in many fields. For example, in a virtual reality system, in order to allow users to have a real sense of immersion visually, the virtual reality device must cover the visual range of the human eye as much as possible. The device is equipped with a specific spherical curvature lens, but when the traditional image is projected into the human eye using the curved lens, the image is distorted, and the human eye has no way to obtain the positioning in the virtual space, that is, your surroundings in virtual reality Both are distorted images. To solve this problem, it is necessary to reverse the image first, generate the distorted image corresponding to the distorted lens through a specific algorithm, and then these disto...
