Device and method for estimating discomfort in watching 3D images by bioelectricity

Abstract

The invention discloses a device and a method for estimating discomfort in watching 3D images by bioelectricity, wherein the device comprises a 3D playing device and a watcher, an electroencephalogram collection recording unit for collecting electroencephalogram signals from the watcher, a myoelectricity collection recording unit for collecting myoelectricity signals from the watcher, a signal processing unit for receiving and processing the collected electroencephalogram signals and the collected myoelectricity signals, and a characteristic quantity extraction part for extracting characteristic quantities from the signal processing unit. The method comprises the following steps: initialization settings of the system, collection of the electroencephalogram signals and the myoelectricity signals, and signal processing. The invention provides the method for estimating the discomfort in watching the 3D images by utilizing bioelectricity signals, which extracts characteristic quantities of the bioelectricity signals indicating discomfort in watching the 3D images by collecting and processing the electroencephalogram signals and the myoelectricity signals so as to estimate the playing effect of a 3D image device; the electroencephalogram signals and the myoelectricity signals of an organism are not influenced by subjective feeling, and are the neuroelectricity physiological response of the organism to the playing effect of the 3D image device, therefore, the estimation method is an objective estimation method with high reliability.

Description

technical field [0001] The invention relates to a device for evaluating the discomfort of viewing 3D images. In particular, it relates to a device and method for evaluating the discomfort of viewing 3D images by bioelectricity using bioelectrical signal methods (including electroencephalogram signals and electromyographic signals). Background technique [0002] The hot screening of the movie "Avatar" made many viewers feel the amazing charm of 3D for the first time in their lives, and aroused strong attention from all walks of life to 3D images. At present, 3D images have been applied to products such as televisions and movies, and are expected to be applied to various aspects of life such as mobile phones, medical imaging, and games in the future. Its application will trigger a revolution in the history of imaging. Samsung, Panasonic, Toshiba, LG and other international first-tier TV manufacturers have launched new 3D TV products, and domestic Konka, TCL, Haier and Hisense...

Problems solved by technology

Subjective evaluation is based on the subject's subjective feelings or experience, mainly by oral and questionnaire, which has the advantages of intuition, simple operation, and easy realization, but this method is easily affected by the subject's subjective factors , the accuracy is not high enough; the objective evaluation is the change of the subject’s visual function and the destruction of the coordination of visual activity time. Currently, there are three measurement methods: direct measurement with instruments, measurement with prisms, eye charts and other tools, and bioelectricity measurement

Scholars at home and abroad have used subjective methods and instrumental measurement methods to evaluate visual discomfort, but the evaluation by bioelectricity measurement has not yet been carried out in China. At present, there are no relevant evaluation standards at home and abroad.
