Abstract
The invention relates to an augmented-reality vehicle-mounted projection system which mainly improves visibility of a car driver in fog or in heavy rain. The vehicle-mounted projection system comprises a set of high-power IRLEDs in the waveband of 840-890 nm and actively irradiates the front portion, images are collected by a lens of a camera and a CCD which is arranged on the back of the lens and can sense the IR waveband and the visible light waveband, a light-passing-through-fog chip is arranged on the back of the CCD, CCD images received by the light-passing-through-fog chip are sent to a CPU for processing, processed images are stored in an RAM, and the projection system projects the processed images to a car windshield pasted with a transparent reflecting film to display the images in real time. By means of the projection system, the purpose of improving visibility of the car driver in fog or in heavy rain is achieved.
Description
Technical field
B60R11/02(2006.01)I。
Background technology
He Kaiming " Single Image Haze Removal Using Dark Channel Prior "; The mist elimination chip BU6521KV of ROHM.
Based on micro-shadow casting technique of LCOS; Based on the Color Laser Projection Technology of MEMS.
Summary of the invention
A kind of vehicle-mounted optical projection system, comprise the high-power IRLED of one group of 840～890nm wave band, initiatively irradiate front, pick up camera is with camera lens and be arranged on the CCD after camera lens with induction IR wave band and visible light wave range and gather, after described CCD, be provided with Penetrating Fog chip, Penetrating Fog chip receives ccd image and transfers to CPU to process, and in RAM, stores image after treatment, and optical projection system shows the image projection of handling well in real time on the windshield that posts transparent reflectance coating.When use, fog-penetrating camera and IRLED external member are arranged on to automobile front beam place, while running into greasy weather or large rainy day, the digital image that CCD is processed into transfers to CPU to process through Penetrating Fog chip, by fuzzy image sharpening, and in RAM, storing image after treatment, optical projection system shows the image projection of handling well in real time on the windshield that posts transparent reflectance coating.This system can reach in the rain or strengthen the object of driver's visibility in mist.
Detailed description of the invention
Native system adopts IRLED initiatively to irradiate front, then with the CCD chip reception image that can respond to infrared band and visible light wave range, then is transferred to Penetrating Fog resume module image, finally with projector by the projecting video image of handling well on the Windshield of automobile.This system can reach in the rain or strengthen the object of driver's visibility in mist.
1. described in, IRLED mainly adopts Infrared High-Power LED, and its wave band is at 840～890nm.This wave band is atmospheric window, and infrared ray has good bite and do not weaken.With the active irradiation of IRLED front, then receive image with the CCD chip that can respond to infrared band and visible light wave range.
2. image transmitting CCD chip being received is to mist elimination resume module.Described Penetrating Fog module is mainly made up of the integrated chip with mist elimination processing capacity, MCU and RAM.The described integrated chip with mist elimination processing capacity can adopt the mist elimination process chip BU6521KV of ROHM or the mist elimination process chip THP7312 of THINE.Penetrating Fog chip receives ccd image and transfers to CPU to process, and in RAM, stores image after treatment, is projected in the image after real-time Graphics Processing on the windshield that posts holographic reflectance coating by minitype projection machine.
3. the micro projection system of telling can adopt the ray machine of micro-shadow casting technique of LCOS or the Color Laser Projection Technology based on MEMS.Optical projection system is made up of ray machine and reflectance coating.Selecting of the ray machine of telling is main according to the distance of institute's projection video image, can select the ray machine of different light quantitys.Reflectance coating can adopt the holographic reflectance coating of the MP based on hologram (hologram) technology.Optical projection system shows the image projection of handling well in real time on the windshield that posts transparent reflectance coating.The video image of projection can above driver's sight line or below.
Claims (1)
