The embodiment of the invention provides a Guest OS starting exception detection method and system, and the method comprises the steps: recording the starting moment of a virtual machine instance in response to a detected starting event of the virtual machine instance; under the condition that the virtual machine instance is in the running state, determining whether the virtual machine instance successfully responds to a detection request sent by a host machine where the virtual machine instance is located or not; if it is confirmed that the predefined starting exception judgment condition is met, it is judged that starting of a guest operating system Guest OS on the virtual machine instance is abnormal; wherein the startup exception judgment condition comprises that the virtual machine instance does not successfully respond to the detection request within a preset duration after the startup moment.

This invention discloses an adaptive thermally excited infrared thermal wave nondestructive testing method and device. The method includes: querying a pre-stored database based on the scanned position signal to obtain the theoretical standard energy distribution spectrum under the current pose; triggering pre-aiming sensing; acquiring and generating the actual pre-aiming energy distribution spectrum; comparing the two to calculate the actual energy non-uniformity, and comparing it with a preset threshold to decide whether to initiate compensation; driving the actuator to perform physical adjustments and confirming the adjustments; and finally synchronously triggering the main thermal excitation and infrared thermal image acquisition. The device includes a scanning motion and pose feedback module, a high-precision multispectral pre-aiming sensing module, an intelligent decision-making and synchronous control module, a finely adjustable main excitation execution module, and a data management and communication interface module. This invention can proactively correct the uneven excitation energy distribution caused by scanning geometric changes from the physical source, significantly improving the quality and reliability of the detected image.

This invention discloses a method for constructing a seamless land-water DEM based on multi-source satellite data fusion. The study area is divided into bare land, drawdown zone, and perennial waterlogged area based on the annual average water frequency of Sentinel-2 imagery. Using the ICESat-2 ATL08 ground point cloud during the dry season and contemporaneous Sentinel-2 imagery, the underwater topography of the drawdown zone is constructed using an XGBoost model. Using the ATL13 water surface elevation and depth during the wet season and contemporaneous Sentinel-2 imagery, the underwater topography of the perennial waterlogged area is constructed. Based on the water frequency, the results from the drawdown zone and the perennial waterlogged area are fused to generate a complete and continuous underwater topography. The elevation of the bare land ALOS DEM is then corrected using the ATL08 point cloud and fused with the topography of the drawdown zone and the perennial waterlogged area, achieving a seamless connection between land and water topography and constructing a high-precision integrated land-water DEM, thus improving the accuracy of the water area and shoreline topography.
