Description

Technical Field

[0001] The utility model belongs to the technical field of aerial photogrammetry devices and relates to a telescopic quick-joint aerial survey image control point ground mark making tool. Background Art

[0002] At present, there are many forms of deploying UAV aerial survey control point signs, including purchasing ready-made easy-to-identify disposable ground signs, purchasing reusable ground signs, spraying white or red paint on the road surface and other places, and sprinkling white lime on cultivated land, forests and grasslands. The ground signs sprayed or sprinkled on site are mostly "+" and "L" types.

[0003] Purchasing disposable ground signs increases operating costs, and purchasing reusable ground signs also has the disadvantage of increased costs. In addition, in field surveying, the use of image control point ground signs will increase operating time and personnel costs. At present, the most widely used and low-cost methods are on-site spraying or sprinkling ground signs, which are mostly "+" and "L" types. The width of "+" and "L" type ground signs is usually greater than 15cm, and the length is usually greater than 50cm. The size of the sign is related to the altitude of the drone and the ground resolution of the camera. There are two major difficulties in making ground signs: one is that the degree of refinement of ground signs is closely related to the accuracy of the aerial photography internal work points. The precise edges and corners of the signs, the neatness of the edges, the consistent width, the right angle standard, etc. are all content of the refinement of the signs; the second is that it is more difficult to spray or sprinkle ground signs when there is wind.
