摘　　要：为了更好地保障数据拼接的有效性,提出基于线结构光的3D手持扫描仪数据拼接方法。通过对数据拼接过程中产生的差异数值进行加权计算,优化其特征权重,获取数据共性特征,并对数据特征参数曲率进行计算,对计算结果进行去噪处理,从而有效实现对3D手持扫描仪数据拼接方法的优化。最后通过实验证明,基于线结构光的3D手持扫描仪数据拼接方法相对于传统方法而言有更高的有效性和实用性,充分满足研究要求。In order to better guarantee the effectiveness of data splicing,a 3 D handheld scanner data splicing method based on line structured light is proposed.Through the weighted calculation of the difference values generated in the data splicing process,the characteristic weight is optimized,the common characteristics of the data are obtained,the curvature of the data characteristic parameters is calculated,and the calculation results are denoised,thus effectively realizing the optimization of the data splicing method of the 3 D handheld scanner.Finally,the experiment proves that the 3 D handheld scanner data splicing method based on line structured light is more effective and practical than the traditional method,and it fully meets the research requirements.
