The program must plot the behavior of the position, the angle of rotation, the linear and angular velocity of an intruder that penetrates a region filled with a confined granular medium.
The color range by which colored objects are tracked throughout the video must be selected.
There are only two files:
-
By using this file, the range values are already selected and the color abjects are tracked according to this range.
hsv = cv2.cvtColor(frame, cv2.COLOR_BGR2HSV) #Convert colors space
# Blue range
hMin_A=83
sMin_A=138
vMin_A=45
hMax_A=114
sMax_A=200
vMax_A=255-
By using this file, the range values are selected by means of sliders in a GUI and the color abjects are tracked according to this range.
cv2.namedWindow('Blue')
cv2.resizeWindow('Blue',500,300)

video = cv2.VideoCapture('videos/GOPR0656.MP4')This is my first repo, so I thought it would be appropiate to start with my first Python project back 2017, when I was an engineering student. I only made a small change to the code to resolve some compatibilities with opencv-python 4.8. I intend to upgrade it and work on it.
