Embodiment Construction

[0055] In order to make those skilled in the art understand better, the following in conjunction with the attached figure 1 And attached image 3 This method is further described in detail. Using this method to detect visual fatigue of a stereoscopic movie, the process mainly includes four stages: setting the environment, practicing demonstration, watching and measuring, and data processing.

[0056] 1. Setting up the environment

[0057] The viewing environment mainly includes a 23-inch polarized glasses-type stereoscopic display, near-point distance measurement equipment, flash fusion critical frequency measurement equipment, rotatable mobile seats and a host. The brightness, contrast and other parameters of the display are set to recommended values ​​(ITU-R BT.500). Near-point distance measurement equipment is self-made, and a 50 cm long steel ruler is fixed on an iron stand, and there is a visual mark that can move back and forth on the steel ruler. The optotype is a ...

Abstract

The invention discloses a three-dimensional display asthenopia detection system and method. The three-dimensional display asthenopia detection system comprises three-dimensional display equipment, flicker fusion critical frequency (CFF) measuring equipment, near point distance (NPD) measuring equipment and a data processing unit, wherein the CFF measuring equipment is used for collecting a CFF when a user watches three-dimensional display and transmitting the CFF to the data processing unit, the NPD measuring equipment is used for collecting a NPD when the user watches the three-dimensional display and transmitting the NPD to the data processing unit, the data processing unit comprises a three-dimensional asthenopia prediction model, and the three-dimensional asthenopia prediction model predicates the three-dimensional asthenopia of the user according to the input CFF and the NPD. The three-dimensional display asthenopia detection system and method can rapidly detect the asthenopia degree caused by three-dimensional display, and can be used for evaluating three-dimensional display equipment and content and guiding equipment to produce and manufacture comfortable three-dimensional resources and the like.

Description

technical field [0001] The invention belongs to the field of three-dimensional display evaluation, and in particular relates to a three-dimensional display visual fatigue detection system and method. Background technique [0002] In recent years, stereoscopic display technology has been used more and more in fields such as television broadcasting, video games, conferences, medical care, education, and commerce. Although its application benefits consumers and merchants, the development of stereoscopic display technology is currently hindered due to technical and cost constraints. The main reason is that there is a conflict between the imaging principle of 3D display and the working mechanism of the human visual system, resulting in side effects that cannot be ignored in 3D display. For example, watching stereoscopic images / videos for a long time can cause discomfort such as eye fatigue, dizziness, and vomiting to the viewer. There are even studies showing that viewing stere...
