The invention relates to a system and method for synchronously acquiring an object surface three-dimensional color point cloud model. The system comprises an electric displacement platform, a hybrid wavelength band light source and a digital image receiving unit, and is characterized in that the hybrid wavelength band light source is installed on a displacement plate of the electric displacement platform and used for irradiating a measured object, the digital image receiving unit is used for acquiring an image of the measured object, the digital image receiving unit is located above the hybrid wavelength band light source, a servo motor in the electric displacement platform is connected to a motion control card through a motion control cable, the digital image receiving unit is connected to an image acquisition card through a video cable, and both the motion control card and the image acquisition card are connected to a PCI-E expansion slot of a computer. The method comprises the steps of putting the measured object at a set position in front of the electric displacement platform; turning on the hybrid wavelength band light source, and irradiating on the measured object; acquiring a digital image sequence of the measured object; and building a three-dimensional color model of the measured object. The three-dimensional color point cloud model of the measured object can be acquired through one-time scanning according to the invention.
