ASSESSMENT OF THE PROPERTIES OF ASPHALT MODIFIED WITH USED TIRES [PDF]

open access: yesCivil Engineering Journal, 2017
This study investigates the properties of asphalt mix modified with ground tire. The ground tire was introduced into the asphalt in a melted form at varying percentages of 2%, 4%, 6%, 8% and 10% by weight of the asphalt.

Evaluation on the Accuracy of Structure From Motion(SfM)Photogrammetry on Gully Surveying

open access: yesShuitu baochi yanjiu, 2020
A typical gully was selected and measured using the tape method and structure from motion(SfM)photogrammetry in the village of Liangjianfang, Luanping County, Hebei Province. The accuracies of both gully surveying methods were evaluated via comparing the

Learning to Detect Ground Control Points for Improving the Accuracy of Stereo Matching [PDF]

open access: yes2014 IEEE Conference on Computer Vision and Pattern Recognition, 2014
While machine learning has been instrumental to the ongoing progress in most areas of computer vision, it has not been applied to the problem of stereo matching with similar frequency or success. We present a supervised learning approach for predicting the correctness of stereo matches based on a random forest and a set of features that capture various

Accuracy Analysis of a Dam Model from Drone Surveys

open access: yesSensors, 2017
This paper investigates the accuracy of models obtained by drone surveys. To this end, this work analyzes how the placement of ground control points (GCPs) used to georeference the dense point cloud of a dam affects the resulting three-dimensional (3D ...
