摘要
在电容层析成像系统(ECT)中,实时图像重建的速度是一个迫切需要解决的问题,而已有的算法也未能很好地提高重建图像的精度.消除图像重建中数值不稳定性的有效方法是正则化法.利用了基于能量约束的有约束最小二乘法来实现图像重建,由于该算法的计算量与速度最快的LBP算法相当,并用DSP来实现算法,因此,图像重建的速度和精度都得到了解决.
In ECT system,the speed of real time image reconstruction is an urgent problem to be resolved,but the existing algorithms can't improve the accuracy of the image better.Regularization is an effective way to eliminate such an instability.The least square approximation base on energy constraint is applied to realize image reconstruction and DSP is used to realize the algorithm.Asaresult the speed and accuracy of image reconstruction is solved better.
