本发明提供基于超声波层析成像的气液固三相分相含率的测量方法，涉及流体检测领域。该方法包括对管道中气相和液相距离的采集，从而获得气相含率；对管道截面进行超声波层析成像，通过优化的TSVD正则化方法进行成像，将成像图通过SURF处理以及二值化后获得固相含率和液相含率。采用本发明的气液固三相流分相含率测量方法能够在无损检测的情况下获得各相含率，提高强干扰环境中测量各相含率的精度。 The invention provides a gas-liquid-solid three-phase split-phase holdup measuring method based on ultrasonic tomography, and relates to the field of fluid detection. The method comprises the following steps: collecting the distance between a gas phase and a liquid phase in a pipeline so as to obtain the gas phase holdup; and carrying out ultrasonic tomography on the section of the pipeline, carrying out imaging through an optimized TSVD regularization method, and carrying out SURF processing and binarization on an imaging picture to obtain a solid phase holdup and a liquid phase holdup. By adopting the gas-liquid-solid three-phase flow split-phase holdup measuring method, the holdup of each phase can be obtained under the condition of nondestructive testing, and the precision of measuring the v of each phase in a strong in
