Description
[technical field]
The present invention relates to a kind of interactive projection machine system, belong to field of projector.
[background technology]
The classics of projector and computing machine are combined in modern each field has extensive and deep application.Traditional projector and some simplification of the cooperation between the computing machine only are to pass to another direction from a direction.Electronic whiteboard is in the ascendant in recent years, and it makes projector realize interactive function, but shortcoming is, projector must rely on other equipment to accomplish alternately, and the electronic whiteboard volume is heavy, and adaptability is very poor.
Compared with prior art; This interactive projection machine provides a kind of man-machine interaction method of uniqueness; Traditional electronic whiteboard completion interactive process is different with using; Do not need a special electronic whiteboard, only need to rely on projector can accomplish reciprocal process separately, widened occasion and environment that projector uses.
[summary of the invention]
The object of the present invention is to provide a kind of interactive projection machine system; This system has changed the pattern that projector in the past can only show annex as computing machine; A kind of novel computer interactive methods are provided, and the process that makes projection has vividly been expanded the function of projector.
The objective of the invention is to reach: a kind of interactive projection machine system through following measure; Comprise image detection locating device (1) and camera lens (2); It is characterized in that: be provided with light-dividing device (5) in the light path of said camera lens (2); Allow projected image to projection screen, and the light signal light path that camera lens (2) institute's reception luminous indication (6) produces in projection screen is changed to image detection locating device (1); Said image detection locating device (1) comprises imageing sensor (3) and camera lens (4), and camera lens (4) is installed in imageing sensor (3) and goes up and receive the light signal that comes from the light-dividing device reflection; Image processing and analyzing module (7) is analyzed imageing sensor (3) is connected the back acquisition with camera lens (4) image; And calculate the position coordinates of image; Reach computing machine through interface again; Computing machine shines upon position coordinates and computer screen coordinate through computed in software, thereby the control computer cursor moves to the relevant position in the projection screen that luminous indication (6) points to, and computing machine is provided with and controls said image detection locating device (1) through interface.
The light signal that described luminous indication (6) produces in drop shadow spread is the infrared ray signal.
Described camera lens contains an infrared fileter in (4), and it allows IR to get into camera lens (4) to obtain high-quality infrared ray signal, improves signal to noise ratio (S/N ratio).
