一种图像采集方法及图像采集系统
摘要：
本发明公开了一种图像采集方法，其包括以下步骤：(1)获取图像原始信号xn×n；(2)根据模型ψn×nxn×n＝sn×n得到图像稀疏信号sn×n，其中ψn×n为正交变换基；(3)根据模型An×msn×n＝bm×m得到图像测量信号bm×m，其中An×m为测量矩阵，n>>m；(4)求解满足模型的最稀疏向量(5)根据模型得到图像重建信号本发明所述的图像采集方法，其基于压缩感知理论设计，压缩与采样同步，可实现更加高效的压缩采样、存储、传输和恢复。本发明还公开了一种图像采集系统，其采用上述图像采集方法实现对图像的实时采集。
摘要（英）：

The invention discloses an image acquisition method, comprising the steps of (1) acquiring image original signals x; (2) obtaining image sparse signals s according to a model x=s, wherein is an orthogonal transform base; (3) obtaining image measurement signals b according to a model As=b, wherein An*m is a measurement matrix, n>>m; (4) solving for the most sparse vector (as shown in the description) satisfying a model (as shown in the description) (5) and obtaining an image reconstruction signal (as shown in the description) based on a model (as shown in the description). The image acquisition method described by the invention is design based on a compressed sensing theory, with compression and sampling synchronized, and can achieve efficient compression sampling, storage, transmission and recovery. The invention further discloses an image acquisition system which uses the image acquisition method for real-time image acquisition.
