基于视频导航的智能车系统的设计与实现

AbstractThis topic in the thirteenth session of the national collegestudents'smart car competition as the background,main cars byoptimizing the program algorithm and improve the speed andstability of the smart car.The intelligent car system is a complexsystem composed of hardware,software and mechanical structure.The 32-bit single-chip computer MK60N512ZVLQ10 produced by"NXP"semiconductor company is used as the main control chip.The track video image is collected through MT9V032 camera.Because the smart car itself is a very big integral calculation,so inorder to reduce the amount of calculation software algorithm,thePID control algorithm of motor drive speed control of PD two,willI set to zero.In order to ensure the safety of Angle steering andmake the calculation easy,a conservative strategy is adopted.Thesteering gear is controlled by the fixed value of P in PID controlalgorithm.Through the reasonable control of the master controlchip,the whole intelligent car system can finally achieve thecontrol of "straight road full speed,safe curve through".Key words:smart car camera center line PID control algorithm
