Description
Technical field
The utility model is that collection automatic control technology, image detecting technique, Eltec are the auxiliary device of one.The utility model relates to a kind of automotive safety technical field, is the device that the vehicle front obstacle is detected.
Background technology
At present, the system aspect the vehicle front detection of obstacles is limited.Mainly contain the detection of multi-sensor information fusion technology to the place ahead obstacle, laser radar is to the detection of the place ahead obstacle and ultrasonic radar these three kinds of patterns of detection to the place ahead obstacle, multisensor and laser radar cost are too high, bulky and heavy, though and the super sonic cost is lower, but the obstacle that accuracy of detection is relatively poor and road pavement is less is difficult to detect, and is subjected to inside even from weather bigger.Current automobile industry is constantly to the high speed intelligent development, needs therefore that a use of design is simple, reliability is high, survey precision is high, fireballing disturbance of intelligence quality testing is surveyed device.The place ahead obstacle detection system based on the binocular recognition system then has higher relatively preceence.
Summary of the invention
The purpose of this utility model is at the technical matters that will solve obstacle detector before the car, and the device of obstacle before a kind of inspection vehicle is provided.This device can detect the position of obstacle before the car, reminds chaufeur, and makes initiatively brake.
To achieve these goals, the utility model is by the following technical solutions:
A kind ofly comprise display lamp based on binocular recognition system vehicle front detection of obstacles auxiliary device, annunciator, model is the LCDs of LCD12864, MC9S12XS128 micro controller system, vehicle-mounted computer, initiatively brake system and be used for two cameras of measuring distance.
Two pick up cameras are installed in the left and right sides of vehicle front respectively, the focal length difference of two cameras.Camera and model are that the external interface on the micro controller system of MC9S12XS128 links to each other.Eight display lamps are that eight interfaces on the micro controller system of MC9S12XS128 link to each other with model respectively.Annunciator is connected on the interface on the micro controller system that model is MC9S12XS128.Model is that 14 interfaces and the model on the micro controller system of MC9S12XS128 is that 14 interfaces on the LCDs of LCD12864 link to each other.Model is to link to each other on eight external interfaces and the vehicle-mounted computer on the micro controller system of MC9S12XS128.Vehicle-mounted computer links to each other with the active brake system again.
Algorithm is found range according to the binocular vision principle in this device, tests the speed, and then judges whether dangerous.
There is the focal length of two cameras to be respectively f1 and f2; The length of testee is h, is u to the vertical distance of lens; H1 is the imaging length that testee passes through camera 1, and h2 is the imaging length that testee passes through camera 2.By the above-mentioned object distance computing formula that obtains.
Judge to continue to travel whether can bump against according to the variation apart from the lining of surveying with the place ahead obstacle.
Eight display lamps are used for showing situation separately, and annunciator by the voice suggestion chaufeur, makes it that vigilance be arranged when dangerous.Be to show the particular location that records speed, distance and obstacle on the LCDs of LCD12864 in model.
Initiatively brake system is to be used for the control brake, when the place ahead obstacle gradually the time near vehicle, and judgement can stop vehicle ', initiatively brake system will initiatively be braked, and avoids the collision of vehicle and obstacle.
The beneficial effects of the utility model are, initiatively brake, and when forwardly obstacle being arranged, self-actuating brake is for running car provides safety.With binocular vision principle ranging and range rate, improved accuracy.Remind chaufeur whether obstacle is arranged with the voice annunciator.The job information of whole device is provided to chaufeur with display lamp.This installs and compares with laser or radar, and use is simple, reliability is high, survey precision is high.
