Constant volume system, constant volume method, constant volume device and computer storage medium

The invention discloses a constant volume system, a constant volume method, a constant volume device and a computer storage medium relates to the technical field of space volume measurement, and aimsto solve the problem of accurate measurement of fluid in a container under the condition of not contacting the fluid. The constant volume system is applied to a container for containing fluid, and comprises an image acquisition device for scanning environmental information of an inner cavity of the container, a non-contact distance measuring device used for measuring the distance between the fluidcontained in the container and the inlet of the inner cavity of the container in a non-contact manner to obtain fluid level related information; and a terminal equipment electrically connected with the image acquisition device and the non-contact distance measurement device. The constant volume system provided by the technical scheme is applied to the constant volume method. The constant volume device comprises the consta
