Description
Technical field
It is oriented to the present invention relates to line holographic projections technical field, more particularly to a kind of 3D signalized intersections based on augmented reality
Optical projection system.
Background technology
Three-Dimensional Interaction Technology refers to the threedimensional model for creating product in a computer, is then handed over by interaction design software set
Mutual program, allows user to implement the emerging technology of man-machine interaction by interactive devices such as mouses.Three-Dimensional Interaction Technology application is wide
It is general, can be in coordinating products in kind to show together in exhibition, dynamic demonstration is attractive eyeball, product details is showed more again
Presentation tool when understanding that marketing personnel promote, makes product introduction more in place, and client is easier to understand, and shows on enterprise web site,
Innovation form promotes work with reference to the symbol that high-tech marketing gimmick is company new master image and rich strength as the market propaganda
Have, intuitively the gimmick of content-form and novelty makes one not to be sick of, reduction marketing link is said when a dynamic product of seat is used
Bright book, client sees easily again understandable, more convenient using product.
Signalized intersections are important parts in City road traffic system, and pass is played in the linking of road traffic
The effect of key.But, because intersection is the area that direct conflict was mutually walked, existed in all kinds of traffic flows, and with high poly-
Collection property and conflicting so that its traffic bottlenecks for turning into whole city road network.The scientific management of intersection is to ensureing intersection
Safety plays the role of important, and wherein signal lamp is a kind of effective management and control device at present.However, raw in China's reality
In work, signalized intersections generally existing the phenomenon of target vehicle or pedestrian running red light, and all parts of the country all because driver exists
Intersection is made a dash across the red light, is gone through stop light and there occurs a lot of serious traffic accidents, and the safety to pedestrian and target vehicle is caused
Huge threat.According to the Beijing Communication accident statistics data display of 2004,2,005 two years, more than 50% urban transportation
Accident occurs in intersection, and the suburb traffic accident more than 30% occurs in intersection.In recent years, in order to solve intersection target
The problem of running red light for vehicle, domestic and foreign scholars have carried out substantial amounts of research to this, go deep into to this problem behind reason
Analysis, present invention discover that it is to cause driver to be not intended to the main cause made a dash across the red light that driver is absorbed in " awkward area ".
The content of the invention
Optical projection system is oriented to the invention provides a kind of 3D signalized intersections based on augmented reality, including obtains target carriage
Operational factor and traffic lights become lamp parameter；Judge whether target vehicle has the trend in entrance " awkward area ", if so,
The orientation and projection duration of line holographic projections instrument projection are then calculated, is started line holographic projections instrument and is exported to target vehicle driver
The hologram image of warning picture；If no, not processing；Also include holographic projection module, positioning unit, orientation detection
Unit, human action detection unit, the webserver, network data base, microprocessor, wireless communication module.
The positioning unit is sent to microprocessor for collecting the real-time geographical locations information of user, and generating framing signal
Device；
The acquisition target vehicle operational factor, including：The speed v of target vehicle, target vehicle are away from stop line apart from L, pre-
If time of driver's reaction t, target vehicle average acceleration a, intersection width W, the average vehicle commander l of target vehicle；Obtain traffic
Signal lamp consolidation lamp parameter, including：Green light residual time length Tg, amber light duration Ty；Target vehicle is away from parking when calculating amber light opens bright
Line apart from S, formula is as follows：S=L-Tg × v；Target vehicle minimum safe stopping distance S1 is calculated, formula is as follows：The amber light phase
Between target vehicle can pass through apart from S2, formula is as follows：S2=Ty × v；If S ＞ 0, the target vehicle is not absorbed in " faces a difficult choice
The trend in area ", during green light；If S ＞ 0, the target vehicle is not absorbed in the trend in " awkward area ", in the emergency phase
Between；If S ＜ S1, S2 ＜ S+W+l, the target vehicle have the trend for being absorbed in " awkward area ".
The actual traffic existing for advantage and existing signalized intersections that the present invention passes through combination line holographic projections technology is asked
Topic, the present invention proposes to be applied to line holographic projections technology in the management and control of city signal intersection, vivid by line holographic projections
Warning picture gives warning in advance to the target vehicle that will sink into " awkward area ", so as to play a part of safety guiding to driver.
