Problems solved by technology

[0005] (1) The existing technology affects the explanation effect when some conditions in the control are not met in the PPT screening
[0006] (2) The existing technology does not combine the dual recognition scheme of camera face + skeleton for PPT control, which cannot improve the efficiency of explanation
[0007] (3) Existing PPT explanation equipment cannot remotely interact with listeners
[0009] (1) With all the current technologies, the usual way to explain PPT is to use a mouse, keyboard or presenter, and there will be some discomfort during use

Embodiment

[0100] 1. The integrated gesture control PPT system based on cloud-side collaboration technology provided by the present invention includes (such as figure 2 shown):

[0101] Choice of camera A:

[0102] To achieve accurate recognition of human body poses, it is necessary for the camera that captures the human body to have a higher RGB sensor resolution and frame rate, as well as a wider range of depth and distance. Therefore, the present invention selects the intel Realsense D435 depth camera most suitable for the product of the present invention on the market today. Its RGB sensor resolution and frame rate can reach 1920×1080, 30fps, and the depth distance range can reach 0.105m~10m. It exceeds 95% of the products on the market, but the price is only slightly higher than the average of the cameras on the market.

[0103] Selection of edge devices:

[0104] Since the camera of the present invention cannot be used on a PC, it needs to be connected to an edge device. Howe...

Abstract

The invention belongs to the technical field of PPT intelligent control, and discloses an integrated gesture control PPT system and method based on a cloud edge cooperation technology, and a platform. An edge device obtains human joint coordinate original data; a network transmission technology is selected; three-dimensional reconstruction is performed; human body postures are judged through a random forest model; and a preset software program runs on a PC for controlling a PPT, and corresponding keyboard and mouse operation is carried out according to a data analysis result transmitted from the cloud to finish corresponding PPT operation. According to the invention, the next page of the PPT can be turned over by swinging the hand leftwards, the previous page of the PPT can be turned over by swinging the hand rightwards, a laser pen can be called out by one finger of the hand, and highlighter marking can be carried out by scratching the hand. A shadow following teaching platform provided by the invention is an auxiliary teaching platform which can support a teacher to upload the PPT and students to download the PPT, and can realize that the teacher plays the PPT and uploads the PPT at the same time.

Description

technical field [0001] The invention belongs to the technical field of PPT intelligent control, and in particular relates to an integrated gesture control PPT system, method, computer equipment, computer-readable storage medium, and teaching cloud platform based on cloud-edge collaboration technology. Background technique [0002] At present, in the process of teacher's lecture, organization report, and enterprise press conference, the present invention needs to show PPT. However, I often encounter various situations: the presenter is not brought, the presenter is out of battery, and the computer controlling the PPT is too far away, so I have to find someone to control the PPT. Seriously affected the effect of explanation. [0003] If there is a product that can complete a wonderful PPT explanation with only two hands without the constraints of equipment, and can even write and draw in the air when needed, it will definitely greatly facilitate the PPT explainer. So new pro...
