| titleOfInvention | It is divided based on gradient sequence and the curve of mapping policy describes and matching process |
| abstract | The present invention relates to a kind of curve description based on the division of gradient sequence and mapping policy and matching process, it include: to shoot two width different images of Same Scene from different perspectives and input computer, using Canny edge detection operator respectively to two images march Line segment detection, it determines the supporting zone of curve and calculates principal direction, sub-zone dividing is carried out to supporting zone based on gradient magnitude, calculate the gradient sequence characteristics of each available point in supporting zone, gradient sequence characteristics are mapped as 24 dimensional vector features, calculate subregion description and curve description, son is described using curve and Curve Matching is carried out based on bi-directional matching principle.The instability problem that method provided by the invention can overcome the matching process for having and dividing based on gray scale sequence to face has more preferably matching performance. |
