The invention relates to an image defect de-weighting detection method and device based on three-dimensional reconstruction. The method comprises the steps that a to-be-detected image set in a target scene is acquired, to-be-detected images in the to-be-detected image set carry defect labeling areas, two-dimensional feature points of each to-be-detected image are extracted, two-dimensional feature point matching comparison is carried out on every two to-be-detected images, matching result data of the two-dimensional feature points are obtained, and the matching result data of the two-dimensional feature points are obtained. The matching result data of the two-dimensional feature points comprises a matching relationship of the two-dimensional feature points, performing three-dimensional reconstruction based on the matching relationship and the to-be-detected image to obtain a three-dimensional scene point cloud corresponding to the target scene and an association relationship between the to-be-detected image a
