| description | The invention relates to a horizontal pipe flow velocity calculation method and device, computer equipment, a horizontal pipe flow velocity detection system and a storage medium. The method comprises the following steps: acquiring electrical resistance tomographic imaging of a cross section of a horizontal pipe at a first moment; calculating a pixel point proportion at the first moment according to the electrical resistance tomographic imaging; performing calculation according to the pixel proportion at the first moment, the maximum flow velocity pixel point proportion and the minimum flow velocity pixel point proportion to obtain a flow velocity proportion coefficient; and performing the calculation according to the flow velocity proportionality coefficient, the maximum flow velocity and the minimum flow velocity to obtain a flow velocity of the horizontal pipe at the first moment. By adopting the method, the need to consider the problem that a freezing hypothesis cannot be strictly met in an actual process |
