Embodiment Construction

[0115] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0116] figure 1 Shown is a schematic diagram of the scene of the "water-air coordination" mobile positioning system, which includes a water area positioning system, an air space positioning system and a ground control decision-making platform. The application of this system can realize the water-air coordinated aqueduct crack detection and positioning method. The main working steps are as follows:

[0117] The control decision-making platform is initialized and started, and then the AUV and UAV are controlled to work. The AUV is initialized and started, and then the aqueduct crack detection is performed. When a crack is detected, the AUV first determines its position in the world coordinate system, then processes the crack picture taken by the AUV through the binocular vision positioning method to determin...

Abstract

The invention discloses a water-air cooperative aqueduct crack detecting and positioning method, and belongs to the technical field of detection and positioning. According to the method, an underwaterrobot and an aerial unmanned aerial vehicle are used for cooperatively detecting an aqueduct crack and determining the position of the aqueduct crack from an airspace and a water area, a control center compares detection results of equipment in the two areas, and if cracks exist on only one side of an aqueduct, crack position coordinates are stored so that direct comparison can be conducted in the later-period re-detection process; if it is detected that cracks exist at the same positions of the two sides of the aqueduct, crack position coordinates and detection results are stored, and repairinformation is sent out. According to the method, water-air two-domain crack position information comparison is adopted, the damage severity degree of the aqueduct can be judged more accurately, andmore accurate positioning information is provided for crack maintenance of the aqueduct.

Description

technical field [0001] The invention relates to the technical field of detection and positioning, in particular to a water-air coordinated detection and positioning method for aqueduct cracks. Background technique [0002] In order to solve the problem of unbalanced distribution of water resources in time and space and realize the optimal allocation of water resources, cross-regional, cross-basin, and long-distance water diversion projects can be adopted. If there are cracks in the aqueduct of the water diversion project, it will not only cause waste of water resources, but also cause the failure of the entire construction project. Therefore, it is very important to detect whether there are cracks in the aqueduct and accurately determine the location of the cracks for maintenance personnel to repair the aqueduct in time. [0003] For airspace detection and positioning, existing research includes GPS differential positioning technology, high-precision UAV navigation system b...
