In traffic simulation, intersection is the basic unit that we often need to meet. When simulating the traffic flow through the intersection, if you use the previous method, you need to define three traffic flows and move in three different directions. However, in sumo, the simulation of traffic turning at an intersection is realized by jtrouter ...

I introduce Anomaly detection (Anomaly detection) is one of the most mature applications of time series data analysis. It is defined as the process of identifying abnormal events or behaviors from normal time series. Effective anomaly detection is widely used in many real-world areas, such as quantitative transactions, network security testing ...

1, Introduction to UAV 0 Introduction With the development of modern technology, there are more and more types of aircraft, and their applications are becoming more and more specific and perfect, such as Dajiang PS-X625 UAV specially used for plant protection, Baoji Xingyi aviation technology X8 UAV used for street view shooting and monitoring ...

Introduction: The intelligent vehicle system designed in this paper takes NXP RT1064 microcontroller as the core control unit, and detects the track information through the camera in front of the vehicle body; The real-time speed of the model vehicle is detected by the gear encoder, the speed of the left and right motors is adjusted by the ...

Problems with Octomap   recently, I was running LEGO loam with VLP-16, and found that the three-dimensional map can not be used in navigation, so I still need to use the two-dimensional grid map. Therefore, you need to use octomap to convert a 3D map to a 2D map. At the beginning of use, there were many problems. It took a day to finally ...

Random talk about Autonomous vehicle_ 06 I ReadMe Bloggers used autoware1 Version 12.0, but the installation process of this version is slightly cumbersome, and there will be a problem of flower screen, which will be a headache for novices. Therefore, you can directly skip the old version (although 1.14.0 is also old...) and install a versi ...
