【摘要】 传统控制方法存在控制效果差的问题,提出了基于沿扫描线方向梯度信息的质量控制技术。根据扫描像元与空间距离的质量控制原理对信息进行预处理,保证质量控制信息的有效性;对空间梯度信息水平方向和竖直方向信息进行提取,由此可获得新的观测信息,并对梯度扫描基线信息进行检验;从弧段数据质量对控制技术展开研究,利用沿扫描线控制方法进行空间梯度信息质量控制的研究;设计对比实验,完成实验验证。通过实验结果可知,该技术质量控制效果良好。更多还原

【Abstract】 The traditional control method has the problem of poor control effect, and the quality control technology based on the gradient information of the scanning line is proposed. According to the quality control principle of scanning pixel and space distance to preprocess the information, to ensure the effectiveness of the quality control of information; spatial gradient information in the horizontal direction and the vertical direction of information extraction, which can obtain new observation information, and to test the gradient scanning baseline information; from the arc data quality control technology research use, along the scan line control method of spatial gradient information quality control; design experiment, finish the experiment. The result of the experiment shows that the quality control effect of the technology is good.更多还原
