This invention provides a method and system for evaluating the consistency of multiple / subsequent vessel segmentation results. It involves reading the original data of a vessel dataset and multiple / subsequent vessel segmentation result matrices, then randomly selecting two vessel segmentation result matrices to calculate their union, intersection, and symmetric difference. Any point in the symmetric difference is selected, and iterative growth is performed using a convolution kernel to simulate a path diffusion process. Under the constraints of the union range and a given geodesic distance, a spherical set is obtained. The intersection of this spherical set with the union of the vessel segmentation result matrices and the intersection of this intersection with the two / subsequent vessel segmentation result matrices are calculated. The above calculations and statistical analysis are performed on each point to obtain statistical results, which are then mapped back to the original data and the two / subsequent vessel segmentation result matrices. This yields the statistical results for any two / subsequent vessel segmentation result matrices, and the visualized results are output. This invention can be used to measure the performance of vessel segmentation algorithms or compare their differences, accelerating the development and verification process of vessel segmentation algorithms.

This utility model discloses a chemical storage component and a water tank cleaning base station. The chemical storage component includes a storage chamber and a detection mechanism. The storage chamber stores the chemical, and the outlet allows the base station to supply the chemical to the water tank and / or cleaning equipment, meeting the need for adding chemical during water tank maintenance. The detection mechanism can detect the chemical level, solving the problem in existing technologies where users cannot know the chemical level in the base station in a timely manner. Users no longer need to spend time and effort checking the chemical level periodically, reducing maintenance costs. Moreover, it avoids situations where the water quality in the tank cannot be effectively adjusted due to the failure to detect the chemical depletion in time, ensuring the normal use and hygiene of the water tank.
