The invention relates to a photometric stereo image source acquisition method based on a single-pixel imaging system and color modulation, which comprises: generating a series of color measurement templates by a computer, and projecting the color measurement templates onto a three-dimensional target through a color projector. The color measurement template is received by the detector after being reflected by the three-dimensional target. Because the green filter, the red filter and the blue filter are respectively arranged in front of the three groups of detectors, each detector can only receive the wave band range gated by the corresponding filter. Every time a frame of measurement template is projected, each barrel detector records a corresponding measurement value and transmits the measurement value to a computer through a data acquisition terminal, and two-dimensional image reconstruction is carried out in the computer. And when a two-dimensional image corresponding to each barrel detector is reconstructe
