Abstract

The invention discloses a low-memory footprint real-time single pixel imaging method, belongs to the technical field of image processing and provides a method for achieving low-memory real-time computational correlated imaging by using a two-dimensional Hadamard derivative base. A simple and fast fixed transformation result of the two-dimensional Hadamard derivative base is stored into an upper computer control system application program, corresponds to a digital micromirror device loading memory pattern and is correlated to a corresponding target echo signal for computation, so that the storage memory is reduced and the real-time continuous resolution imaging effect of computational correlated imaging is improved.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a real-time single-pixel imaging method with low memory occupation. Background technique [0002] Correlation imaging, also known as ghost imaging, single-pixel imaging, and quantum imaging, is a new imaging method based on the high-order correlation characteristics of light fields. Different from the traditional imaging that uses a multi-pixel detector with spatial resolution to directly record the spatial information of the target, correlated imaging uses a single-pixel detector to record the total intensity value of the echo signal irradiated to the specific code of the object. Values ​​and codes irradiated to the target object are associated with the operation to obtain the object image. [0003] Correlative imaging systems generally use laser light to irradiate rotating frosted glass to generate random coding patterns, and use a beamsplitter prism to sp...
