LIQUID LEVEL MEASUREMENT METHOD, CAPACITY MEASUREMENT METHOD, AND DEVICE AND STORAGE MEDIUM

WIPO Patent Application WO/2024/001732

A1

Disclosed in the present invention are a liquid level measurement method, a capacity measurement method, and a device and a storage medium. In the measurement method, an indirect measurement is performed on a liquid level height by using a laser, wherein the indirect measurement involves measuring a plurality of auxiliary objects, and then obtaining the liquid level height by performing calculations by means of the auxiliary objects. By means of the measurement method, the adverse impact of a change, occurring when the laser propagates in different media, on ranging is corrected, such that by means of laser ranging, the effect of measuring the liquid level height of a transparent liquid, container capacity and amount of stored liquid in different transparent media combinations can be achieved, and in particular, the measurement of the capacity of a container containing the transparent liquid, and the amount of stored liquid therein can be achieved. The measurement method has the characteristics of no contact, high precision, easy implementation, a strong anti-interference capability and a low cost, and achieves a dynamic monitoring effect of the change in the level and amount of the transparent liquid.
