The 3D reconstruction technique using the straight-line segments as features has high precision and low computational cost.
The method is especially suitable for large-scale urban datasets.
However, the line matching step in the existing method has a mismatching problem.
The two main reasons for this problem are the line detection result is not located at the true edge of the image and there is no consistency check of the matching pair.
In order to solve this problem, a linear correction and matching method for 3D reconstruction of target line structure is proposed in this paper.
Firstly, the edge features of the image are extracted to obtain a binarized edge map.
Then, the extended gradient map is calculated using the edge map and the gradient to establish the gradient gravitational map.
Secondly, the straight-line detection method is used to extract all the linear features used for the 3D reconstruction image, and the linear position is corrected by the gradient gravitational map.
Finally, the point feature matching result is used to calculate the polar line, and the line matching results of the adjacent three images are used to determine the final partial check feature area.
Then, random sampling is used to obtain the feature similarity check line matching result in the small neighborhood.
The aforementioned steps can eliminate the mismatched lines.
The experimental results demonstrate that the 3D model obtained using the proposed method has higher integrity and accuracy than the existing methods.
