Petroleum bubble tracking method and device based on single-pixel computational imaging

Abstract

The invention relates to the technical field of optical imaging and petroleum industry monitoring, in particular to a petroleum bubble tracking method and device based on single-pixel calculation imaging, and can solve the problem that a traditional single-pixel technology needs a large number of projection patterns or a complex iterative algorithm and is difficult to meet the real-time tracking requirement to a certain extent. The petroleum bubble tracking method based on single-pixel computational imaging comprises the following steps: generating four groups of sine or cosine coded illumination patterns with different phase characteristics; projecting the illumination pattern to the surface of the petroleum liquid through a spatial light modulator; receiving a reflected light signal modulated by the petroleum surface through a photoelectric detector, and converting the light signal into an electric signal; and calculating the displacement and the motion trail of the petroleum bubbles according to the electric signals in combination with Fourier linear phase shift characteristics.
