摘　　要：为了解决定位不精准、测量过程中出现抖动以及投影镜头无法投影到中心点的问题,提出一种基于GPS测绘技术的建筑物外立面轮廓测量方法。利用GPS接收机、数据处理软件和气象设备构建卫星测量系统,并根据距离交会法完成导航定位,采用相位法计算获取出空间坐标,通过相位参数及其参考面构建光栅投影模型,计算获得相位高度,基于神经网络明确高度与相位映射间关系,依据样本输入、训练完成最终测量结果的输出。仿真实验结果表明,所提方法可以针对不同建筑类型,有效提取出建筑外立面轮廓形状、结构以及纹理,并且测量结果精确度较高,说明该方法具有实际有效性。In order to solve the problems of inaccurate positioning,jitter in the measurement process and the projection lens can not be projected to the center point,a method of building facade contour measurement based on GPS mapping technology is proposed.Using GPS receiver,data processing software and meteorological equipment build satellite measurement system,and complete navigation and positioning according to the distance intersection method,use phase method to calculate the spatial coordinates,through the phase parameters and its reference plane to build grating projection model,calculate the phase height,based on the neural network to clarify the relationship between height and phase mapping,according to the sample input and training to complete the final measurement results output.Simulation results show that the proposed algorithm can effectively extract the shape,structure and texture of building facade for different building types,and the accuracy of the measurement results is high,which shows that the method is practical and effective.
