This invention relates to the field of physical oceanography, specifically to a method for rapidly identifying the upper and lower boundaries of the ocean thermocline. The method utilizes trigonometric functions as basis functions to construct a 10th-order trigonometric polynomial, and obtains the fitting parameters and results using the least squares method. Then, the first derivative of the trigonometric polynomial is calculated. The maximum value and its location, as well as all minimum values ​​and their locations, are determined. From the location of the maximum value, the two locations of the first minimum values ​​less than 1 / 10 of the maximum value are found on both sides. This yields the upper and lower boundaries of the ocean thermocline depth. This invention eliminates the subjectivity of parameter selection by eliminating the need for manually setting thresholds; it also avoids complex transformation and construction processes, resulting in a clear algorithm structure and high computational efficiency. It can operate stably in different sea areas and under various data precision conditions, significantly improving the automation, robustness, and computational efficiency of thermocline identification.

This invention relates to the field of machine vision inspection technology, and discloses a method and system for electrode inspection based on a combined light source. By using a combination of an arched light source and a linear coaxial light source to illuminate the electrode, and dynamically adjusting the illumination brightness and edge intensity threshold according to the silicon content of the electrode, unified settings for imaging parameters and edge detection parameters are achieved. This eliminates the need for frequent recalibration for electrodes with different silicon contents, significantly reducing debugging workload and improving inspection consistency. Simultaneously, the combined light source can accommodate the imaging needs of electrodes with different silicon contents, effectively enhancing the grayscale contrast between the thinned area, slot, and the electrode body. This avoids problems such as unstable edge detection and misjudgment of wrinkles under a single light source, thus achieving unified and stable detection of various defects such as residual cleaning in the slot, missed cleaning in the slot, and missing foil in the thinned area, meeting the high-quality inspection requirements for electrodes with different silicon contents in mass production.

This invention relates to a high-precision prediction method for satellite inertial attitude applicable to large time delays. The method constructs a projection relationship between satellite motion characteristics and predicted attitude, and uses linear difference of reference attitude and adaptive polynomial fitting for attitude extrapolation in dynamic and steady-state processes, respectively, to achieve high-precision attitude prediction in the initial stage of dynamic positioning and stable tracking process, ensuring the extrapolation accuracy of satellite attitude maneuvering and stable tracking process under large time delays.
