Which brand of aerial mapping drone is better?

In the past, many aerial surveys of unmanned aerial vehicles used orthophoto technology to collect image data and GIS information, but the orthophoto camera has its limitations that can not be ignored: it mainly obtains the vertical information of the ground, but can not completely obtain the side information of steep objects. A friend of the Bureau of Surveying and Mapping said that another drone company in Chengdu is good, called Aoshi. Their main products are orthophoto cameras or tilt cameras, which have more loads to match and can meet the different needs of customers. Taking tilt camera as an example, UAV can shoot in all directions through vertical and tilt angles, easily perceive complex scenes, effectively make up for the lack of angle when orthophoto camera obtains aerial images, and reflect the actual situation of ground objects more comprehensively and vividly. Moreover, through the use of supporting software, images can be extracted in batches and drawn on a large scale, which effectively improves the visual effect, quality reliability and drawing efficiency of real 3D models.
