Vision subsidiary navigation system must be high reality and robustness

but no one algorithm in it can overcome the influence brought by the variational surroundings

and be the best in all kinds of road conditions.The self-adaptive road detection method based on reconfigurable hardware technique and road scene matching is presented

which implements the best matching between algorithms and scenes based on the classification of road scenes

and implements algorithm hardware reconfiguration in real time based on reconfigurable hardware

to realizes self-adaptive road detection in vehicle vision navigation.Experiments show it has advantage of good test performance

strong robust

high reality.Detecting precision can reach 90.17 %

and it indicated that this method settles the conflict between self-adaptability and reality in detection system.
