Stage smoke onsite manufacturing platform used for dry ice spraying

Abstract

The invention relates to a stage smoke onsite manufacturing platform used for dry ice spraying. The platform comprises a dry ice spraying device, a movement driving device, a hemisphere type camera, and an overall analysis device. The dry ice spraying device is arranged on one side of a stage main place and used for spraying dry ice towards the stage main place so as to provide stage smoke effectsand create atmospheres for performance on the stage main place. The movement driving device is arranged under the dry ice spraying device, and used for carrying out the dry ice spraying device to drive the dry ice spraying device to move. The hemisphere type camera is used for carrying out immediate image shooting on the stage main place so as to acquire and output a corresponding stage main place image. The overall analysis device is connected with the hemisphere type camera and used for receiving the stage main place image and determining an overall segmentation threshold corresponding to the stage main place image according to distribution conditions of pixel values of each pixel point in the stage main place image. According to the invention, the cost performance of the stage dry icespraying is improved.

Description

Technical field [0001] The invention relates to the field of stage effect creation, in particular to a stage smoke field manufacturing platform based on dry ice spraying. Background technique [0002] Dry ice is also called solid carbon dioxide. Under atmospheric pressure, the solid is directly converted into gas without passing through the liquid. This phenomenon is called sublimation. Spraying dry ice on the stage rapidly sublimates and absorbs heat and turns into gas, condensing the surrounding water vapor into smoke, which is the common smoke effect of dry ice. In addition, because the specific gravity of carbon dioxide is 1.5 times that of polite, then it flows down to the stage to form a low smoke, so dry ice is used on the stage like this; if you use a large professional dry ice machine to put dry ice on the stage, it will The feeling of spray, the scene covered by smoke on the stage performance is made in this way. [0003] The appearance of the fog effect on the dry ice...

Problems solved by technology

[0004] In order to solve the technical problem that the amount of stage dry ice spraying in the prior art is difficult to control, the present invention provides a field manufacturing platform for stage smoke based on dry ice spraying, which realizes the actual size of various stage main sites through a targeted image detection mechanism. Detection, spraying the corresponding dose of dry ice based on the determined actual size, so as to achieve a balance between ensuring the on-site effect and saving the dose of dry ice; on the basis of block processing, only perform feature enhancement operations on blocks with more edge pixels, Thereby reducing the amount of image processing data; establishing an adaptive adjustment mode based on the overall threshold to adjust the block threshold, so that the target detection takes into account the overall characteristics and characteristics, and ensures the validity of the target image to be processed for subsequent image processing
