Problems solved by technology

The projection system plays an important role in people's work, study and entertainment occasions, but the current projection system requires people to manually operate and play, and the interactivity is not good. For example, in the field of education, the interactive atmosphere of the speaker is discounted. In the field of entertainment, it is impossible to build a friendly environment that can be interactively perceived, so there are shortcomings

Embodiment Construction

[0031] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements. As mentioned above, such as figure 1 As shown, this embodiment provides a projection method that supports gesture interaction, and the projection method includes the following steps:

[0032] S001 Start the computer, camera and projector, the projection system is in working condition, adjust the viewing angle of the camera to capture the entire projection screen;

[0033] The S002 camera continuously photographs and collects images on the projection screen according to the preset time interval, performs binarization processing, and uses the subtraction method to perform differential calculations between the continuously collected images to obtain screen change differential images including moving hand projections;

[0034] S003 Calculate the density distribution characteristics of the target area according to the obtained ...

Abstract

The invention discloses a gesture-interaction-supported projection method. A projection system is in the working state, a whole projection screen can be captured by adjusting the visual angle of a camera, the projection screen is shot continuously through a camera according to preset time intervals to collect images, binarization processing is executed, differential operation is conducted on the collected images through a difference image method, and screen change difference images containing projection of a moving hand portion are obtained; according to the obtained continuous difference images, the target region density distribution feature is computed, gesture identification and gesture track detection are conducted, a handshape type or a gesture command type is judged, and the projection content of a projector is controlled and adjusted. By means of the method, human body input actions can be recognized, the projection figure content is adjusted according to different movement trend of gestures, good human-computer interaction is achieved, and the method has good application prospects.

Description

technical field [0001] The present invention relates to the technical fields of projection display and image processing, in particular to a projection method and projection system supporting gesture interaction. Background technique [0002] With the rapid development of science and technology and the rapid expansion of information, in many fields such as film and television animation industry, digital and virtual cities and communities, architectural design and planning, automobile design and manufacturing, remote sensing and command, and large-scale scientific computing visualization, people The requirements for display technology are also getting higher and higher. The projection system plays an important role in people's work, study and entertainment occasions, but the current projection system requires people to manually operate and play, and the interactivity is not good. For example, in the field of education, the interactive atmosphere of the speaker is discounted. ...
