Abstract
The invention discloses a transparent automobile backseat projection display system. The system comprises a high-speed photographing module installed right in the middle of the tail of an automobile and used for acquiring mirror images behind the automobile, a signal processing module used for receiving video signals of the high-speed photographing module and processing the images, a projection module installed above a cab or on the back face of a driver seat and used for projecting the images processed through the signal processing module to the rear portion in the automobile and a storage module used for storing data of the signal processing module. The system has the beneficial effects that a reflecting type ultra-short focus miniature projection device is used for replacing a traditional liquid crystal display screen, the color gamut is wide, the contrast ratio and saturability are high, and power consumption is low.
Description
Technical field
The present invention relates to a kind of transparent automotive backseat projection display system, be mainly used in the projection art of rear seat for vehicle.
Background technology
Constantly soaring along with automobile quantity, the accident caused by automobile also gets more and more, therefore, people enjoy convenience that driving brings to us and joyful time, traffic safety is also subject to people's attention more and more.The situations such as existing article such as the suspension of domestic sedan car back vehicle windshield place down toy and Chair back cushion etc., vehicle are full often cause chaufeur cannot be observed the situation of rear view of vehicle by rear-viewing mirror in vehicle, and vehicle side rearview mirror visual field is little, there is vision area blind spot, particularly because chaufeur is positioned at left side, grasp more difficult to right rear, when easily causing vehicle merge and turn, occur that vehicle scratches, knock the traffic accidents such as child down when moveing backward.Therefore, be necessary that providing a kind of can expand the visual field of driver and automobile rear can be provided without the rear-view system for automobile of dead angle real scene to driver.
In prior art, No. CN03129429.4, application number patent discloses a kind of automobile multifunction intelligent backsight screen, namely at cabin design read-out, monitors rear view of vehicle, be mainly used in reversing and the backsight of automobile by tailstock shooting all-dimensional multi-angle.Described back-sight visual system can not provide the actual size image of object after car for driver, be not easy to the distance that chaufeur judges this car relatively of object after car at once, and traditional LCDs colour gamut, contrast ratio, degree of saturation specific humidity, power consumption all can not compared with projection arrangements.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of transparent automotive backseat projection display system, reflective ultrashort burnt micro projector is adopted to instead of traditional LCDs, it is wide that it has colour gamut, high-contrast, high saturation, the advantages such as low-power consumption, and the image of object after car can be presented in proportion, chaufeur is felt, and back seat " transparent do not exist " is general, thus the distance of object this car relative after easily judging car, reduce traffic accident, be therefore applicable to very much replacing Liquid Crystal Display and be used for back seat display system.
The present invention is achieved through the following technical solutions.
A kind of transparent automotive backseat projection display system, comprising:
High-speed camera module, is arranged on middle, tailstock portion, for obtaining car rear mirror image;
Signal processing module, for receiving the vision signal of above-mentioned high-speed camera module and carrying out image procossing;
Projection module, is arranged on above operator's compartment or the operating seat back side, for by the rear in car of the image projection after signal processing module process;
Memory module, for the data of storage signal processing module.
Further, above-mentioned high-speed camera module comprises wide-angle camera.
Further, above-mentioned wide-angle camera is the wide-angle camera being not less than 60 frames/second.
Further, above-mentioned wide-angle camera comprises visible image capturing head and infrared camera.
Further, above-mentioned signal processing module comprises on-site programmable gate array FPGA.
Further, above-mentioned projection module comprises illumination equipment, digital micromirror array DMD, reflective ultrashort out-of-focus projection object lens.
Beneficial effect of the present invention:
1, large-sized picture.Make chaufeur in reversing process, do not exist equally by back seat projection sensation back seat is transparent, allow vehicle body all things below with the form of solid, be presented in face of chaufeur, allow chaufeur take leave of parking reversing neurosis.Avoid because bumping against blind area obstacle, and vehicle is damaged or people by vehicle injury, driver can monitor the image of rear view of vehicle more clear, more broadly, improve drive personnel reversing safety and convenience.
2, higher resolution, can project picture more clearly.
3, can project on any nonplanar object.
4, in the automobile of high temperature, the product of DLP technology still can normally work.
