Abstract

The invention belongs to the technical field of computational imaging, and particularly relates to a moving target real-time capture single-pixel imaging method and device. The real-time imaging method comprises the following steps: S1, generating a two-dimensional modulation matrix, loading the two-dimensional modulation matrix into an optical modulator, receiving an optical signal which is reflected by a target object or penetrates through the target object through the optical modulator, and modulating the optical signal by using the two-dimensional modulation matrix; s2, calculating a modulated light information intensity value through single-pixel detectors in two complementary directions; s3, calculating the position of the mass center of the target object according to a mass center solving algorithm; and S4, reconstructing a target image by adopting a motion compensation single-pixel algorithm according to the position of the center of mass and the intensity value of the modulated optical signal. According to the invention, accurate imaging of a high-speed moving target can be realized, and smear and blurring are avoided.

Description

technical field [0001] The invention belongs to the technical field of computational imaging, and particularly relates to a single-pixel imaging method and device for real-time capture of moving objects. Background technique [0002] In the field of imaging, the traditional method is to directly acquire spatially resolved images through an area array sensor with spatial resolution, and the imaging quality largely depends on the number of pixels of the area array sensor. In recent years, single-pixel imaging has gradually gained attention because its imaging quality does not depend on the number of sensor pixels, only one single-pixel detector is used, and it has high sensitivity and high spectral adaptability. Different from the traditional camera imaging method, the single-pixel imaging system uses a single-pixel detector to measure the time-resolved light intensity signal by spatially modulating the object light information, and then reconstructs the target image through c...
