Abstract
The utility model discloses a traffic sign identification voice prompting apparatus which is used for subjecting traffic signs and traffic police command hand signals to automatic image identification, wherein the traffic sign identification voice prompting apparatus is also used for broadcasting the signs and signals in a voice mode, time spent by a driver looking at the signs and identifying the signs and hand signals can be reduced, and therefore the driver can be lowered in driving pressure. The traffic sign identification voice prompting apparatus comprises a processor, a traffic sign image acquisition unit, a traffic sign template storage device and a voice unit, wherein the processor is connected with the traffic sign image acquisition unit, the traffic sign template storage device and the voice unit.
Description
Technical field
The utility model relates to pattern recognition device, especially designs a kind of for traffic sign being carried out to image recognition on automobile and carrying out the device of voice reminder.
Background technology
Traffic sign is the one of traffic control device, form a kind of traffic language with shape, color, pattern, word etc., all users on all roads are moved in an orderly manner, thereby the security that on the one hand improves road improve the traffic efficiency of road on the other hand.Driving license test is also classified traffic sign as important theory examination content, but because traffic sign is relatively many, driver there will be unacquainted mark or gesture unavoidably, for such situation, under the more and more intelligentized megatrend of automobile, can be on automobile integrated a kind of device, this device can be realized the form of the mark running into and traffic police's gesture voice to driver to remind, and sees the pressure of roadside signs to alleviate driver.
Within open day, be that patent documentation that Dec 21, publication number in 2005 are CN 1710628A discloses the technical scheme that name is called a kind of traffic prompt system, it comprises that in the car being placed in car, traffic information acceptance system is pointed out emission coefficient outward with the car that is placed in road cross and traffic mark place, receiving system central processing unit is embedded with receiving control system, emission coefficient central processing unit is embedded with launch control system, receives car and point out the security warning information of emission coefficient in car outward.The weak point of this technical scheme is, traffic alarm (mark) need to be installed wireless launcher, classification and number due to various traffic signs in reality are more, such as various warning notices, alert order mark and Warning Mark etc., on road, that wireless transmitting system cost is installed is too high for each mark, installs and uses all very inconvenient.
Summary of the invention
The utility model fundamental purpose is to provide a kind of Traffic Sign Recognition speech prompting device, it commands gesture automatically carry out image recognition and report out with the form of voice Road traffic signs and traffic police, can reduce the time that driver sees mark and distinguishing mark and gesture, therefore can alleviate driver's motoring pressure.
The utility model is mainly solved by following technical proposals for prior art problem, a kind of Traffic Sign Recognition speech prompting device, comprise processor, Traffic Sign Images collecting unit, traffic sign template storage and voice unit, processor connects respectively Traffic Sign Images collecting unit, traffic sign template storage and voice unit.
The technical program, in the time of automobile starting, automatically move, the warning notice in Traffic Sign Images collecting unit collection vehicle front, prohibitory sign, the fixed signals such as Warning Mark and traffic police's sign gesture information, and the flag information collecting and gesture information are sent to processor, in processor, mate calculating with the mark template in traffic sign template storage, judge traffic sign, the connotation content that traffic police's gesture is represented, controlling voice unit will indicate in time, the standard information of gesture is reported to driver with the form of voice broadcast, remind driver to note transport information.Wherein traffic sign template comprises various traffic sign templates and traffic police's sign gesture template.
As preferably, sign image collecting unit is colored digital camera.Adopting digital vedio recording first is can directly connect processor to carry out image acquisition simplification device structure, the 2nd, digitized image acquisition and process and can reduce image noise, improve the signal to noise ratio (S/N ratio) of camera, and can increase the dynamic range of camera and maximize the tonal range of image.
As preferably, colored digital camera is low-luminance color digital camera head.Low-luminance color camera, compared with infrared camera, still can obtain coloured image under night low-illumination condition, has improved the recognition accuracy of traffic sign.
As preferably, low-luminance color digital camera head is arranged on the coboundary of windshield glass of automobile, and camera lens is towards dead ahead.Camera broad view can be made, the sign gesture of traffic police on the traffic sign of roadside, front, road top and road can be conveniently obtained.
As preferably, voice unit comprises chipspeech and vehicle multimedia playing system, and chipspeech connects respectively processor and vehicle multimedia playing system.Because traffic sign quantity is many, record, play inconvenience by address segmentation, therefore, processor adopts mark content to send to chipspeech with word packet mode, then is converted to voice by chipspeech and sends to vehicle multimedia playing system and play.Utilize vehicle multimedia playing system to play, can reduce equipment redundancy, simplification device structure.Wherein vehicle multimedia playing system comprises microcontroller, note amplifier and loudspeaker etc.
As preferably, vehicle multimedia playing system connects described processor by CAN bus.Automatically being controlled switching on and shutting down, the source of sound of vehicle multimedia playing system by processor selects (chipspeech selection), speech data to operations such as chipspeech transmissions.
The beneficial effect that the utility model brings is, by vehicle-mounted camera, the traffic sign running into and traffic police's gesture information are inputed to processor and carry out identifying processing, by voice unit, mark and gesture are carried and offered driver with the form of sound, reduce driver and seen the time of mark and distinguishing mark and sign gesture, thereby also alleviated driver's motoring pressure.
