This invention provides a calibration-free path reconstruction method for buried cables based on Topo-NeRF and active sensing. Addressing the issues of traditional magnetic field inversion relying on calibration and being prone to mismatch in environments with strong interference such as reinforced concrete, the method preprocesses raw data to obtain a spatiotemporal feature matrix. This matrix undergoes feature extraction, spatial alignment, and drift compensation to eliminate extrinsic parameter calibration, resulting in multi-source fused data. This multi-source fused data is combined to characterize the cable's magnetic field using a continuous three-dimensional topological manifold. An implicit neural radiation field is constructed and coupled with differentiable electromagnetic rendering. The cable body and branch nodes are separated within a persistently cohomologically constrained topological bottleneck layer. The initial reconstruction results are combined with conditional diffusion and ground-penetrating radar dielectric priors to enhance low signal-to-noise ratio weak fields, ensuring consistency between the reconstruction results and the underground physical structure. Based on reconstruction uncertainties, topological entropy is calculated, and online acquisition trajectories are planned to form a closed-loop active sensing system. Finally, a three-dimensional path model is output, enabling rapid detection of underground cables.

The application provides a temperature measurement method, system, device, computer device and storage medium. The application corrects a target spectrum signal by using an attenuation coefficient calculated from a reference spectrum signal and a theoretical blackbody radiation value to obtain a corrected radiation amount.

In addition, the link equation of the application realizes joint solving of the emissivity model parameter and the wafer surface temperature, reduces the influence of emissivity uncertainty on the temperature inversion result, thereby realizing high-precision and wide-range measurement of the wafer temperature in a complex process environment, improving the precision of temperature closed-loop control and the process yield, and facilitating engineering application in a compact temperature measurement probe with limited volume.
