However, these methods have the following disadvantages: (1) The visual method mainly relies on the subjective judgment of the staff and cannot be compared quantitatively, so there are human interference factors; (2) The procedure of the topdressing structure depth method is very cumbersome and difficult to implement; (3 ) In the laser structure depth method, the detection points are discontinuous, so the data is easily lost during the processing, so the accuracy cannot be guaranteed

Embodiment Construction
[0013] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0014] figure 1 It is a flow chart of the method for pavement segregation detection provided by the present invention, such as figure 1 As shown, the road surface image is collected first, and then the collected road surface image is digitized to obtain a pixel area of N×M pixels, where N and M are both positive integers. Then divide the pixel area of N×M pixels by n×m pixels to obtain k analysis areas, where n, m, and k are also positive integers, and n≤N, m≤M. Then calculate the number Z of feature pixels in each of the k analysis areas i , i=1-k, where one or more color pixels can be selected as feature pixels. Then the number of feature pixels in eac...

The invention discloses a method and a system for detecting pavement segregation and an engineering machine. The method comprises the following steps: acquiring a pavement image; digitalizing the acquired pavement image to obtain a pixel region of N*M pixels; dividing the pixel region according to the N*M pixels to obtain k analyzing regions; calculating the quantity Zi of characteristic pixels in each analyzing region, wherein i is equal to 1-k; comparing the quantity Zi of the characteristic pixels in each analyzing region with a pre-set threshold value Z, and determining whether the analyzing region is a qualified analyzing region or not according to a comparing result. According to the method and the system for detecting the pavement segregation and the engineering machine, the quantitative and accurate detection on the segregation of a pavement surface is realized by processing the pavement image; the detection method is simple and easy to implement; not only can the detection of pavement or material segregation be carried out rapidly and accurately, but also the accuracy rate is high and the cost is low.
Description
technical field [0001] The invention relates to road surface segregation detection technology, in particular to a method, system and engineering machinery for road surface segregation detection. Background technique [0002] Surface segregation of asphalt mixture is one of the causes of pavement damage, and detection of asphalt mixture surface segregation is an important means to measure the quality of pavement paving. [0003] The traditional detection methods of asphalt pavement surface segregation mainly include: (1) visual inspection method; (2) sand topping structure depth method; (3) laser structure depth method. However, these methods have the following disadvantages: (1) The visual method mainly relies on the subjective judgment of the staff and cannot be compared quantitatively, so there are human interference factors; (2) The procedure of the topdressing structure depth method is very cumbersome and difficult to implement; (3 ) In the laser structure depth method,...
