Embodiment Construction

[0035] The accompanying drawings are for illustrative purposes only and cannot be construed as limiting the patent;

[0036] In order to better illustrate this embodiment, some parts in the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product;

[0037] For those skilled in the art, it is understandable that some well-known structures and descriptions thereof may be omitted in the drawings.

[0038] Such as figure 1 Shown is a schematic diagram of the projection system of the present invention, including a projector, two cameras, and a computing device. The main function of the projector is to project the picture onto any plane. The function of the camera is to capture the projected picture and then transmit it to the computing device. The computing device mainly analyzes the data collected by the camera, and the flow chart of its analysis and processing is as follows: figure 2 shown.

[0039] First, the human hand is extracted ...

Abstract

The invention discloses an interactive projection method and system based on active vision. The method includes the steps that frames needing interaction are projected onto any plane by a projector, information of operation on the projected interaction frames carried out by a user is collected through a shooting device, the shot information is transmitted to a processing unit to be analyzed and processed, and thus corresponding operation of the user is acquired so as to achieve human-computer interaction. An offline training mode is adopted for the processing unit, and thus the detection efficiency is promoted. When data are trained, a new training mechanism is provided, and thus a large amount of manual operation is reduced. In the detection process, a model which is updated in real time is adopted, namely, a current skin color model is only relevant to the last several frames of skin colors, and thus influences of illumination on the skin colors can be effectively eliminated, the algorithm efficiency is effectively improved, and the real time requirement can be totally met.

Description

technical field [0001] The present invention relates to the technical field of computer vision, and more specifically, to an interactive projection method and system based on active vision. [0002] Then perform the corresponding user operation on the screen that needs to be interacted with, and project it to the projection area through the projection device for the user to watch; Background technique [0003] Although multi-channel human-computer interaction technologies that comprehensively use vision, hearing, touch, smell, taste, etc. play an irreplaceable role. At present, the touch system, as the latest computer input device, is the simplest, most convenient and natural way of human-computer interaction. It endows multimedia with a new look and is a very attractive new multimedia interactive device. With the advancement of technology, the use of projectors is becoming more and more convenient. It can turn any flat surface into a display screen. Projectors are widely...
