Embodiment Construction

[0033] The present invention is described in further detail now in conjunction with accompanying drawing.

[0034] The present application provides a signal inspection method based on the principle of the prior art (single-pixel signal acquisition process).

[0035] One, first introduce the acquisition process of single pixel signal (prior art)

[0036] Single-pixel imaging uses a single-pixel detector to sample the object to be imaged through a structured illumination light field with a specific spatial distribution. The structured illumination light field is modulated by the object and then fed back to the light intensity information, which is collected by the single-pixel detector and constantly changes on the modulator. Modulation pattern and synchronous detection, the two-dimensional image of the object can be reconstructed through a series of detection values ​​and modulation patterns for correlation calculation.

[0037] According to the size of the image, design the s...

Abstract

The invention discloses a single-pixel imaging signal detection method. The method comprises the steps that a single-pixel detector designs a sampling matrix according to the size of a detected object and carries out sampling; the sampling matrixes are divided into multiple groups, each group comprises C sampling matrixes, the C sampling matrixes in each group are arranged according to the mode of r rows and columns, for the C sampling matrixes in each group, the sampling matrixes in each row are integrated to obtain a sub-matrix, the sampling matrixes in each column are integrated to obtain a sub-matrix, and the sub-matrix is divided into multiple groups, and the position of a sampling matrix which specifically generates error signals is judged by calculating the sub-matrixes and respective inspection matrixes or projection matrixes of the sub-matrixes, so that the inspection in the signal acquisition process is realized.

Description

technical field [0001] The invention relates to the technical field of imaging technology, in particular to a single-pixel imaging signal inspection method. Background technique [0002] Single-pixel imaging technology is an emerging imaging technology, which uses only a single-pixel detector without spatial resolution to reconstruct the target image at a low sampling rate by encoding the light field. , multispectral imaging, terahertz imaging, infrared imaging and many other fields have received extensive attention. However, during the signal acquisition process, due to circuit delays, counting errors, etc., sampling timing errors may occur, so that image reconstruction cannot be achieved. Therefore, designing a sampling strategy with an error detection mechanism plays a key role in stabilizing system performance. [0003] According to the characteristics of the single-pixel sampling signal, the present invention designs a sampling method of the monitoring signal, and jud...
