Research and realization of intelligent auto-tracing car for adaptability of environment

This paper based on MC9S12XS128 microcontroller and CCD camera which intelligent auto-tracing car using tracking, proposed an innovative method of acclimatizing oneself to environment. The system selected the digital potentiometer AD5160 and comparator LM319 realizes the external hardware binary of the image signal, while through single-chip internal AD acquisition image information, and set compare calculated threshold value dynamically, making the smart car has a certain adaptive ability in complex environmental conditions.
