Method for pavement cracks detection based on multi-scale matrix filtering
In order to quickly detect pavement cracks and classify them from complex pavement environment
a method based on multi-scale matrix filtering is proposed. The method which based on TMS642 DSP platform from TI can process a large number of complex data with high speed in real-time
and effectively process pavement images from multi scales to eliminate the noise
then highlights the characteristics of pavement cracks. Characteristics of pavement cracks can be extracted by analyzing the feature and feature direction of Hessian matrix
then growth direction can be traced and the size of it can be determined. At the same time
the small discontinuous cracks are combined through the crack combination algorithm. Finally
the cracks will be classified according to the crack curvature. Experimental results show that the method proposed in this paper can quickly detect and classify the pavement cracks with high accuracy
it also has strong anti-noise capacity
high image segmentation accuracy and low miss rate and error rate
so it can meet the engineering application requirements.
