Hello everyone,
I am using nvdsanalytics plugin in a pipeline and saving the output video. My questions are regarding nvdsanalytics plugin and its parameters in config file. Please have a look on my following queries-
-
In line-crossing part of nvdsanalytics, it counts by adding “+1” whenever a person crosses the line in the specified direction but how to count by adding “-1” if a person crosses from opposite direction.
what I thought of is creating two lines with opposite direction and of same coordinates, then later using custom plugin(which I don’t know how to build) to find difference between the counts. Please share any other method if exist. -
While defining line-crossing part, the direction parameter requires coordinates of two points which define the direction for counting. Is the direction is very specific? Means for example-
If in a video there is one line along the width(in horizontal direction) and people are moving along the height of video(in vertical direction) Nvdsanalytics will count the person if his direction is along the direction specified in the paramerter. But if a person is crossing line diagonally( not in a straight line) will it count that person? If no then what should be done to count that person.
Thanks in advance.
