Embodiment Construction
[0021] In order to make the objectives, technical solutions, and beneficial effects of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0022] figure 1 Illustratively shows a schematic diagram of a system architecture for VR / AR device definition measurement to which the embodiments of the present invention are applicable, such as figure 1 As shown, the system architecture includes a VR / AR device 100 and a sharpness measuring device 200. Wherein, the sharpness measuring device 200 is arranged outside the VR / AR device 100 for measuring the imaging sharpness of the VR / AR device 100. Among them, the initial image formed by the VR / AR device 100 is displayed on its internal display screen.
[0023] Such as figure 1 As shown...

The embodiment of the invention relates to the technical field of VR / AR, and especially relates to a method and device for measuring the imaging definition of VR / AR equipment, so as to solve a problemin the prior art that a definition measurement result is not accurate during the subjective testing and evaluation of the definition of the VR / AR equipment through human eyes. The device comprises isdisposed outside the VR / AR equipment, and comprises a clamping tool, a collection module, and a processing module. The clamping tool comprises a first support part which is used for supporting the VR / AR equipment, and a second support part which is used for supporting the collection module, wherein the distance between the two support parts is within a preset distance range. The collection moduleis used for collecting an initial image displayed by the VR / AR equipment and obtaining a to-be-detected image. The processing module is used for performing the edge detection of the to-be-detected image, determining the definition of an edge point of the to-be-detected image, and determining the imaging definition of the VR / AR equipment. Therefore, the subjective evaluation via human eyes is changed into quantitative parameters, thereby improving the measurement accuracy of the imaging definition of the VR / AR equipment.
Description
Technical field [0001] The embodiments of the present invention relate to the field of VR / AR technology, and in particular to a method and device for measuring the imaging clarity of VR / AR equipment. Background technique [0002] The basic principle of Virtual Reality (VR) and Augmented Reality (AR) is to form a 3D vision by projecting two virtual images in front of human eyes, through the human eye's own parallax and multi-source information integration. Virtual effect. Clarity is a very important indicator that affects the image quality, and it determines the amount of detail that the imaging system can reproduce. If the definition is low, the sense of reality is not high, which will seriously affect the user experience. Therefore, for VR / AR devices, clarity is an important indicator that determines the user's immersion and realism in a virtual scene. [0003] For the development and production of VR / AR equipment, clarity measurement is a very important link. However, due to ...
