Data Acquisition Method of Oblique Photography in Power Construction Scene Based on DBSCAN Clustering
In view of the omission of photographic record data and the large proportion of measurement data,an inclined photo-grammetric data acquisition method for power construction scene based on DBSCAN clustering is proposed.The method plans the flight route of UAV,makes the lens and PTZ axis in the same center,uses GPS technology to obtain image control point positioning data,applies DBSCAN clustering method to classify data categories,stores and records photo positioning data,and matches UAV POS data and photographed photos one by one.The experimental results show that this method reduces the problem image proportion of the measurement data set and improves the qualified rate of image data.
