Projection system and projection method thereof

Abstract

The invention provides a projection system and a projection method thereof, the projection system comprises an illumination module, a projection module and a control module, the illumination module emits a light beam, the light beam comprises visible light and invisible light, the projection module is arranged on the emergent side of the illumination module, the projection module emits invisible light, and the control module is used for detecting the external environment of the projection system, receiving the invisible light reflected by the external environment so as to analyze the external environment, and controlling the projection generated by the visible light emitted from the projection module.

Description

technical field [0001] The present invention relates to the field of projection, and more particularly relates to a projection system and a projection method thereof. Background technique [0002] Liquid Crystal ON Silicon (LCOS) is an emerging technology of liquid crystal display (LCD), which belongs to the liquid crystal reflective chip, and has the advantages of good color, high contrast and high brightness. In addition, LCOS projection technology has great potential for high-resolution projection. At present, the LCOS projection system is mainly three-chip type. The three-chip type is to split the light source through a beam splitter prism, divide the beam into red, blue, and green light, and then project the beam into three LCOS panels, and the three LCOS panels project separately. After the images of red, blue, and green light are produced, they are combined by the photocombining system to form a color image for projection. [0003] Such as figure 1 The shown existi...

Problems solved by technology

However, the current LCOS projection system cannot perform real-time detection and early warning of the external environment of the projection system, and the projected content cannot correctly reflect the actual situation of the external environment. Good information reminder and safety early warning function

[0007] Moreover, the content and position of the current LCOS projection system cannot be adjusted according to the external environment, and may be projected on obstacles, affecting the quality of projection, and the information is not effectively exhibit

There are also situations where the image is projected onto the human body, causing harm to the human body

Therefore, the projection content and projection position of the current LCOS projection system may not be able to adapt to the external environment, the projection quality may be affected by the external environment, the image cannot be stabilized, the projection position may also be hindered, and the information cannot be effectively obtained. Information reminder and early warning function, if it is in the car projection, driving safety cannot be reliably guaranteed
