Timing data acquisition platform applying visual field analysis

Abstract

The invention relates to a timed data acquisition platform applying visual field analysis, and the platform comprises a timed acquisition device which comprises a timed triggering unit and a plurality of image acquisition units which are respectively arranged at the central positions of a plurality of concave displays, the plurality of image acquisition units are used for respectively acquiring sub-regional images of a playing coverage scene of the corresponding concave display, and the timing trigger unit is used for simultaneously triggering the plurality of image acquisition units to execute an acquisition action by selecting a certain time point in the on-site blanking time; the surrounding type concave display screen is arranged in a video hall and comprises a synchronous control unit, a main controller and a plurality of concave displayers. The timed data acquisition platform applying visual field analysis is compact in design and convenient to control. On the basis of utilizing a timing acquisition mode based on field blanking time and a playing power consumption control mode based on audience detection, intelligent control on field data acquisition and picture playing is realized.

Description

technical field [0001] The invention relates to the field of image acquisition control, in particular to a timing data acquisition platform applying visual field analysis. Background technique [0002] Image is the basis of human vision, an objective reflection of natural scenery, and an important source for human beings to understand the world and human beings themselves. "Picture" is the distribution of light reflected or transmitted by an object, and "image" is the impression or understanding of the picture in the human brain that is accepted by the human visual system, such as photos, paintings, clip art, maps, calligraphy works, handwritten Chinese characters , Faxes, satellite cloud images, film and television screens, X-rays, EEG, ECG, etc. are all images. [0003] An image is a similar and vivid description or portrait of an objective object, and is the most commonly used information carrier in human social activities. In other words, an image is a representation o...

[0005] In the prior art, when a larger screen composed of multiple screens is used to play video images, the playback of some screens is meaningless. For example, the wrap-around concave display screens in the projection halls of some entertainment venues include multiple , if there is no viewer in the playback range scene of a certain concave display, it is inappropriate to use a high power consumption playback mode for the concave display at this time to pursue the playback picture quality
