Embodiment Construction

[0013] Below is further detailed description of the present invention according to accompanying drawing and example:

[0014] figure 1 It is a schematic diagram of the oblique photography control system for three-dimensional modeling according to the present invention. It is characterized in that the system includes an aircraft, a camera and a control system; it adopts dual-lens shooting, and when the system is working, the flight direction is the forward path , the first time the camera takes a picture is at the angle directly below the vertical ground, then it turns towards the flight direction, and takes a second picture after reaching the set angle with the ground, and finally swings to the opposite set angle from the flight direction for the third time Take a picture for the first time, and then return to the neutral position (just below) to stand by. The process of taking pictures three times is called a cycle.

[0015] Further, the control system includes a main contro...

Abstract

The invention discloses an oblique photography control system for three-dimensional modeling. Theo blique photography control system is characterized by comprising an aircraft, a camera and a control system. Double-lens shooting is adopted, when the system works, the flight direction is a forward path, the first shooting of the camera is carried out at an angle position perpendicular to the ground, then the camera rotates towards the flight direction, second shooting is carried out after a preset angle with the ground is reached, third shooting is carried out when the camera swings to a preset angle opposite to the flight direction, then the camera returns to a neutral position for standby, and the process of three times of photographing is called a period. The control system comprises a main controller, a GPS unit, a communication circuit and a sensing monitor, and the whole process is controlled by the main controller, such as the rotation angle of a steering engine, the photographing control of the camera, GPS signal acquisition, photo storage and the like. According to the invention, the data quality, efficiency, weight and cost can be well considered at the same time.

Description

technical field [0001] The present invention relates to the field of unmanned aerial vehicle application, aerial photographing technology of oblique photography camera and 3D modeling technology, especially relates to the oblique photography control system for three-dimensional modeling. Background technique [0002] UAVs are light and flexible, and can be equipped with various types of mission platforms to perform diverse tasks. Among them, aerial images equipped with tilt cameras can collect image information of ground objects from multiple angles, and then establish 3D models. At present, the acquisition of oblique image data of the front, rear, left, right, and lower angles in the domestic market mainly relies on conventional aerial photography platforms. The traditional use of five-lens oblique cameras adopts the method of "fixed five cameras + single flight" Obtain multi-angle and multi-coverage oblique images that meet the needs of 3D modeling. However, these oblique...
