摘要

This Letter proposes a coordinate difference homogenization matching method to solve motion influence in three-dimensional (3D) range-intensity correlation laser imaging.Firstly,features and feature pairs of gate images are obtained by speeded-up robust figures and bi-directional feature matching methods.The original mean value of the feature-pair coordinate differences is calculated.Comparing the coordinate differences with the original mean value,the wrong feature pairs are removed,and then an optimized mean value is updated.The final feature-pair coordinates are re-registered based on the updated mean value.Thus,an accurate transformation is established to rectify motion gate images for 3D reconstruction.In the experiment,a 3D image of a tower at 780 m is successfully captured by our laser gated imaging system on a pan-tilt device.
