Problems solved by technology
Since the instrument is a mechanical device, it has certain requirements for natural conditions, road traffic conditions and energy, so the scope of use is limited
Real-time monitoring of video is the best development at present, but the current video detector is installed on the arm column of the lamp pole, and the monitoring range is limited due to the specific viewing angle

Embodiment Construction
[0027] like figure 1 As shown, a UAV-based traffic status information collection method, including using UAV to collect the video of the traffic condition of the road section to be tested; image processing the video returned by the UAV to obtain relevant data; combined with the traditional floating car method Calculate the traffic status information of the road section to be tested. Specific steps are as follows:
[0028] Step 1. Use the UAV to collect the traffic condition video of the road section to be tested
[0029] The drone mounted with a high-definition camera travels according to the preset route and speed, and transmits the pictures taken on the road section to be tested and the parameters of the drone to the data processing system in the background in real time. For the returned pictures and data, directly on the screen It displays real-time aerial images and various parameters (such as flight altitude, latitude and longitude, real-time power, etc.), and can send ...

The invention discloses a traffic state information acquisition method based on an unmanned aerial vehicle. The method comprises the steps of: acquiring a traffic condition video of a to-be-measured road section by using an unmanned aerial vehicle; performing image processing on the video acquired by the unmanned aerial vehicle to obtain related data; and calculating the traffic state informationof the to-be-measured road section with a floating vehicle method. According to the method of the invention, the advantages of low cost, flexible operation, small safety risk, wide coverage area and immunity to the limitation of road traffic of the unmanned aerial vehicle is are brought into full play, so that point, line and plane traffic detection from a local area to a wide area is achieved, and situations can be rapidly and efficiently controlled by a traffic management department.
Description
technical field [0001] The invention belongs to the field of intelligent transportation, in particular to a method for collecting traffic state information based on an unmanned aerial vehicle. Background technique [0002] The basis and key of traffic monitoring lies in the collection of traffic information. Among the traditional data collection methods, the manual observation method is simple and easy, and can be divided into lanes and vehicle types, and can also measure all vehicles on the entire road. But it requires a lot of manpower, it is easy to fatigue for a long time, and it is difficult to maintain accuracy. Instrument automatic measurement methods include pneumatic, geomagnetic, electromagnetic, ultrasonic, infrared photography, etc. Because the instrument is a mechanical device, it has certain requirements for natural conditions, road traffic conditions and energy, so the scope of use is limited to a certain extent. Real-time monitoring of video is the best de...
