Problems solved by technology
After the problematic data output by the navigation is transmitted to the flight control system, the flight control system will appear to control mixed wheels, which will affect the safe operation of the UAV equipment in severe cases.
[0003] There is no effective method for eliminating GPS measurement outliers in the existing technical solutions, especially in the flight of UAVs, if there are continuous outliers, the current There are algorithms that cannot be culled
Moreover, in the subsequent flight control process, when the control algorithm performs data fusion, it will also strongly track the outlier points of the GPS jump, so that the height data in the control data of the UAV system diverges, causing the UAV equipment to fail. The phenomenon of control, when it is more serious, there may even be a drone explosion

The invention relates to a speed data processing method and device, electronic equipment and a computer readable medium, and relates to the field of computer information processing. The method includes the following steps: obtaining measurement speed of a target object at a current moment; calculating predicted speed of the target object at the current moment; obtaining an evaluation index throughthe measurement speed and the predicted speed; and when the evaluation index is greater than or equal to a predetermined threshold value, taking filtering speed of a last moment as current speed of the target object for subsequent processing. The speed data processing method and device, the electronic equipment and the computer readable medium of the invention can eliminate the influence of an abnormal speed value on a control system of unmanned aerial vehicle equipment to enable the unmanned aerial vehicle equipment to obtain accurate navigation and positioning data.
Description
technical field [0001] The present disclosure relates to the field of computer information processing, in particular, to a speed data processing method, device, electronic equipment and computer readable medium. Background technique [0002] The UAV system is composed of flight control unit, navigation unit, power system unit, power module, cables and so on. After each sub-system unit forms a complete system, it will operate in a unified and coordinated manner to control the safe and accurate flight of the UAV system. In the logistics UAV system, due to the complexity of the distribution environment, there are often external interference and internal system self-interference. Multiple subsystems are integrated on the UAV, which is very vulnerable to electromagnetic interference, which makes the GPS vertical speed outlier. When an interference signal enters the UAV system, the Global Positioning System (GPS) of the UAV will be interfered, and then an outlier point will be g...
