2results about How to "Avoid Calculation Bias" patented technology

This invention discloses a panoramic image stitching and restoration system and method based on feature matching, relating to the field of image processing technology. The system includes capturing images and collecting image capture information; numbering the images based on the collected image capture information; matching feature points of two adjacent numbered images to obtain image feature information; mapping the image numbers and image feature information to a Cartesian coordinate system in stages; setting a triple planning mechanism based on the staged mapping information; planning the image stitching order based on the triple planning mechanism; performing image stitching processing according to the planned image stitching order; and performing restoration processing on the stitched panoramic image. This achieves automated planning of the optimal image stitching order, reduces the accumulation of image stitching errors, and minimizes the impact of poor image stitching quality on subsequent image restoration effects.

This disclosure provides a performance evaluation method for the heat transfer protection effect of pipeline insulation coatings. By introducing an equivalent thermal conductivity model based on microporous structure, a more accurate characterization of the initial thermal insulation performance of the coating is achieved, overcoming the calculation bias caused by relying solely on the inherent thermal conductivity of the material. Secondly, by coupling a performance degradation factor, the model possesses dynamic prediction capabilities, accurately simulating the thermal insulation performance degradation law of the coating throughout its entire life cycle, providing crucial data support for pipeline energy efficiency assessment and preventive maintenance. Finally, by defining a comprehensive thermal protection effectiveness index as the optimization target and utilizing intelligent algorithms to back-optimize construction process parameters, this invention elevates traditional "experience-based design" to "precise optimization design based on performance prediction," thereby maximizing material cost savings, reducing energy consumption, and significantly improving the long-term safety and economy of pipeline systems while ensuring thermal protection effectiveness.
