Abstract

The invention relates to the technical field of imaging, and discloses a single pixel imaging method based on Radon transform. The method comprises the following steps: generating a two-dimensional matrix; executing each row of data of the two-dimensional matrix, and performing backward projection transformation on each row of data of the two-dimensional matrix according to different angles to obtain a two-dimensional projection pattern; transmitting the two-dimensional projection pattern to a structured light generating device so that the structured light generating device modulates light using the two-dimensional projection pattern and irradiates an object to be imaged with the modulated light; obtaining the reflected light intensity response value of the object, calculating the projection distribution function of the object at different angles, and arranging the projection distribution function according to the angle magnitude to obtain the Radon spectrum of the object; The image ofthe object to be imaged is obtained by backward projection transformation of the Radon spectrum. The invention can effectively reduce the cost and complexity of the Radon spectrum acquisition systemand improve the feature extraction, classification and identification efficiency of the single pixel imaging system on the object through the combination of the single pixel imaging and the Radon transform technology.

Description

technical field [0001] The invention relates to the field of imaging technology, in particular to a single-pixel imaging method based on Radon transform. Background technique [0002] The most important source of information in human production and life is images, and imaging detection methods are a major way to obtain images. In recent years, a single-pixel imaging technology that is essentially different from traditional imaging technology in the imaging detection mechanism [M.F.Duarte, M.A.Davenport, D.Takhar, J.N.Laska, T.Sun, K.F.Kelly, R.G.Baraniuk, Single-Pixel Imaging via Compressive Sampling.IEEE SignalProcessingMagazine.25,83-91(2008); Chen Tao, Single-pixel Camera Imaging System Using Compressive Sensing Theory, Optical Precision Engineering, Volume 20, Issue 11, Pages 2523-2530, 2012], due to its People pay more and more attention to the ability to break through the limitations of traditional imaging fields. Compared with the local single-point sampling method ...
