Embodiment Construction

[0030] The present invention will be described in detail below with reference to the embodiments and the accompanying drawings.

[0031] The multi-angle high-definition gimbal camera mounted on the UAV uses the upper and lower gimbal cameras to simultaneously collect image data from one vertical and four oblique angles for solid modeling, and combines the BIM model to achieve user-facing based on this model. The design, construction, and management of the drone are integrated; equipped with GPS, it can use technologies such as inertial navigation and visual positioning. Judgment, get the image coordinates of the target, and then combine the spatial geometric parameters and position information of the measured target to determine the position information of the UAV relative to the target, and reduce the positioning error to a minimum. Infrared ranging is an infrared transmitting device that transmits an infrared signal to the target to be measured. After the infrared signal hit...

Abstract

A bridge appearance quality detection system based on an unmanned aerial vehicle collection platform comprises an unmanned aerial vehicle flight platform and a ground control center, reaches parts which are difficult to touch in traditional manual detection, and can perform simple, rapid and repeated sampling on detail parts; the detection scheme is flexible and variable and can be modified in the background, and multiple alternative schemes can be provided and selected according to the actual situation on site; compared with the prior art, the method has the advantages of higher precision, high efficiency, fast speed and low omission ratio, is more objective and is not affected by subjective effects of people due to the adoption of an image processing technology, and the accuracy of a detection result is better guaranteed.

Description

technical field [0001] The invention relates to the technical field of a bridge appearance quality detection system based on an unmanned aerial vehicle collection platform, in particular to a bridge appearance quality detection. Background technique [0002] On the one hand, the traditional bridge inspection is that the inspectors generally use the bridge inspection vehicle to lower the inspectors to the bottom of the bridge for inspection; Low, difficult, high risk factor, and low detection accuracy. Therefore, a bridge detection device using UAV as a technical platform has appeared, but because UAV photography accuracy and UAV flight stability are far from enough, this is not suitable for UAVs that obtain crack width information by taking long-distance photos. The bridge inspection method is more difficult to realize, which will eventually cause the inspectors to produce larger errors in the later analysis of crack width, length and other diseases. Therefore, structural ...
