The detection of distresses with ground-penetrating radar (GPR) images is a highly challenging task due to their complex structure, blurred boundaries, and varying scales. The Segment Anything Model (SAM) has demonstrated impressive performance in natural image segmentation tasks with its zero-shot segmentation capability and high efficiency, which effectively reduces annotation time. However, the applicability of SAM for GPR image analysis remains till now. To this end, we construct a GPR image dataset comprising 395 samples with segmention, which are jointly confirmed and annotated by multiple domain experts. We comprehensively evaluate the performance of various mainstream deep learning image segmentation models and different SAM models on this dataset, and analyze the results in detail. Our experiments confirm that SAM's performance in detecting underground radar distresses is limited or even completely inadequate. These findings demonstrate that SAM's current zero-shot segmentation capability is insufficient for direct application in subgrade distress with GPR data.
In massive multiple-input multiple-output (MIMO) systems, data converters with low resolution are appropriate because of their low power consumption and cost. Moreover, oversampling for such systems has benefits for t...

In order to realize the periodic surface monitoring and early warning of the multi-terrain realistic 3D model of the landslide, it is for the unmanned aerial vehicle to use multiphase optical images to measure the ground control points during each phase of image acquisition, and proposes an automatic registration algorithm for the terrain-real 3D model, to automatically establish a realistic 3D model of multiple time series with a unified spatial reference. The experimental results show that the average spatial difference of the realistic 3D model after registration is as low as 0.01m. This method is suitable for periodic dynamic surface monitoring and change detection scenarios of landslides and natural high and steep slopes, and has technical advantages such as high precision, low safety risk, low cost, and non-contact surface monitoring.
