plane, the coordinate transformation relation between the ground coordinate system and the camera image coordinate system is deduced in detail, and the conversion relationship between the camera image coordinate system and the computer pixel coordinate system is analyzed. and the similarities and differences between the coordinate transformation and the camera calibration; Finally, a moving object tracking method based on image processing is proposed

absrtact: Since the implementation of microservices, we have encountered a lot of problems. One of the biggest problems is how to troubleshoot, the service interface will often rely on multiple services, the slow dependence of the interface will directly affect the quality of the interface service. The slowness of this dependency is common on-line, but it's not a good reason to investigate ... We are common to Daniel on the line on how to optimize performance, how to improve performance, in

Namenode. In HDFs The server-side project has a dedicated package directory to hold this part of the code. as the startupprogress name shows, the functionality of this module is not a role for HDFS start-up control, but rather a role to initiate tracking and progress reporting . Because there is not much code under the Startupprogress package in HDFs, we can do a detailed analysis. The related class file looks like this:In the total, I have divided t
