Abstract

The invention provides an asphalt pavement texture structure image acquisition device, and belongs to the technical field of image acquisition equipment. Camera devices are arranged on a device frame; the height between the camera device and the asphalt pavement and the camera angle of the camera devices can be adjusted by adjusting the device frame; a plurality of mounting positions are arranged at the top end of the device frame, and the camera devices can be detachably mounted in the mounting positions; and a shading adjusting mechanism is arranged on the device frame in a surrounding mode and used for shading an acquisition range during image acquisition, and a light supplementing device is arranged and used for conducting light supplementing adjustment on the acquisition range during image acquisition. According to the invention, image acquisition of the texture structure of an asphalt pavement under different conditions can be completed, and the uniformity of the asphalt pavement can be evaluated through cooperation of MATLAB software; and the road surface map acquisition device and the using method thereof are easy to operate and large in application range, a single parameter can be simply adjusted, and the road surface map collecting device and the using method have the advantages of being reliable, rapid, economical and the like and have good application and popularization prospects.

Description

technical field [0001] The invention relates to the technical field of image acquisition equipment, in particular to an asphalt pavement texture structure image acquisition device with simple operation and wide application range. Background technique [0002] The construction uniformity of asphalt pavement is the result of the joint action of various components of the mixture, among which the segregation phenomenon formed by the uneven distribution of coarse and fine aggregates has the greatest impact on the pavement construction quality. Inhomogeneity has become one of the main causes of early disease of asphalt pavement. In the segregated area of ​​asphalt pavement, its durability and service life will be reduced by 10%-50%. During the construction process of asphalt pavement and the stage of completion acceptance, it is necessary to reasonably detect and evaluate the uniformity of aggregate distribution of asphalt pavement. [0003] In the coarse aggregate concentration ...
