Abstract: A method of 3D visualization based on Bézier curve is presented according to process and interpretation in seismic data. Keeping data sample density and imaging efficiency in a certain range by interpolating and fitting with quadratic Bézier curve or sampling seismic data. Based on the signal variable character, seismic data is mapped to corresponding vector color domain with cubic Bézier curve. Two ways for parameter quantification are given during transformation. Experimental results show that interpolation based image has obvious stereoscopical and geological character.

Key words: seismic data, Bézier curve, data fitting, color interpolation, texture mapping, 3D visualization

摘要： 针对三维地震数据资料处理和解释环节中的科学计算三维可视化问题，提出一种基于Bézier曲线的处理方法。通过对地震采样数据进行插值拟合或抽样取点的方式，使数据样本点的密度与成像效率保持在一定的范围内。根据地震数据信号变化规律，利用三次Bézier曲线插值的方式，将地震数据映射到相应的颜色向量空间，实现地震数据的三维成像处理，并在构建图像化过程中给出两种参数量化的方法。实验结果表明，该曲线插值方法的图像层次感明显，反映出的地质特征性更强。
