Stage curtain integrity identification mechanism

Abstract

The invention relates to a stage curtain integrity identification mechanism. The mechanism comprises a curtain unfolding device connected to a stage curtain for controlling the stage curtain to be switched between an unfolded state and a contracted state and sending an unfolding prompt signal when the stage curtain is in the unfolded state; a hemisphere camera used for image data capture for the stage curtain to obtain and output a current screen image; a noise detecting device connected to the hemisphere camera for receiving the current screen image and performing noise detection on the current screen image to obtain a noise amplitude corresponding to the current screen image to output the amplitude as the current noise amplitude. The mechanism achieves effective monitoring of the overalldegree of lack of the curtain.

[0003] In order to solve the technical problem that the current stage curtain is missing and cannot be detected, the present invention provides a stage curtain integrity identification mechanism, which adopts a targeted stage curtain integrity identification mechanism. When the area occupied by the stage curtain is less than the preset area threshold, a The curtain lacks signals, thus replacing the detection operation of the human eye; a two-level segmentation mechanism is used to perform targeted enhancement operations on the local areas that most need to be enhanced in the image to be processed, and no enhancement operation is performed on the remaining areas, and a two-level segmentation mechanism is adopted The combination mechanism carries out image reconstruction, thereby ensuring the speed of image processing; by extracting the preliminary target outline of the image, the distribution area where the target of the image is located and the non-distinct area without targets are obtained, and a differentiated image segmentation mode is implemented, and for For each sub-image obtained, adjust the threshold value for stripping the background of the corresponding sub-image based on the width of each dynamic range, thereby realizing the directional segmentation of the foreground image; by defocusing the output image of the hemispherical camera Real-time detection, to determine whether to issue a corresponding out-of-focus alarm according to the real-time detection results, to avoid out-of-focus situations during the shooting process of the dome camera
