基于智能手机的摄影测量前方交会法精度评估
首发时间:2020-05-15
摘要:随着微电子集成技术的发展,智能手机集成相机模块的性能得到不断提升,并在移动支付、人脸识别、智能交通等领域得到广泛应用,然而在专业级别的摄影测量方面的研究和应用还未得到有效关注。为了评估智能手机在摄影测量前方交会中应用的精度水平,本文以小米8手机为例提出了基于近景摄影测量的精度验证方法,通过专业级别的摄影测量软件Agisoft PhotoScan对两个实验结果的精度进行了验证,一个是针对小型墨水盒的前方交会实验,另一个是针对中型桥梁的前方交会实验。墨水盒测试结果得到前方交会的精度在毫米级别,桥梁测试结果得到水平方向的精度在0.3米左右,垂直方向的精度在0.5米左右。测试结果表明,当代智能手机的相机模块在高精度摄影测量方面具有的一定的应用潜力。

Precision evaluation of Forward Intersection method in Photogrammetry of Smartphone
Abstract:With the development of microelectronics integration technology, the performance of camera module integrated with smart phone has been improved, and it has been widely used in mobile payment, face recognition, intelligent transportation and other fields. However, the research and application in professional level photogrammetry has not been effectively concerned. Based on the camera module of Xiaomi 8, this paper evaluates the accuracy level of the application of smart phone in the front intersection of photogrammetry. The accuracy of the two experimental results is verified by using professional photogrammetry software Agisoft Photoscan, one is for the ink box front intersection experiment, the other is for a small bridge front intersection experiment. The ink box test results show that the precision of forward intersection is in millimeter level, the bridge test results show that the precision of horizontal direction is about 0.3m, and the precision of vertical direction is about 0.5m. The test results show that the camera module of smart phone has certain application potential in high-precision photogrammetry.
