1results about How to "Reduce surface irregularities" patented technology

The invention discloses a target point cloud enhancement and curved surface fitting method for sensing integration, which solves the problems of high requirement on computing power and no fidelity in the prior art, and realizes high-precision and high-integrity three-dimensional real-time reconstruction of a complex urban environment under the condition of not depending on training data. The method comprises the following steps: acquiring original frequency domain data, extracting corresponding time domain channel response vectors, and stacking the time domain channel response vectors to obtain an echo matrix; performing distance dimension detection and spatial spectrum estimation according to the echo matrix to obtain an original sparse point cloud set and the signal amplitude of each point; performing weighted condensation processing based on signal amplitude on the original sparse point cloud set to obtain a denoised point cloud skeleton; performing local surface fitting and smooth projection on the point cloud skeleton based on a moving least square method to obtain a smooth point cloud; and performing iterative edge splitting interpolation under spatial constraint on the smooth point cloud until the point cloud density meets a preset condition, and outputting the enhanced dense point cloud.
