Gun Detection using Python-OpenCV | weapon detection project

 Gun detection using Open CV is a very useful project for your resume and also useful for real-life projects. Many industries use this kind of technology for weapon detection. So it will be great if you can make such a project using python in very simple steps.

Difficulty:

It will be very simple code. By using some simple method of OpenCV(open source computer vision) you can create this project and have some fun

Modules:

1. OpenCV(for installation use pip install opencv-python on your terminal)
2. NumPy(for installation use pip install numpy)
3. Imutils(for installation use pip install imutils)
4. Datetime(you don't need to install it)

Notes:

In this project, I use a pre-ready dataset for detecting guns you can get it from here

Code:

import numpy as np

import cv2

import imutils

import datetime

gun_cascade = cv2.CascadeClassifier('cascade.xml')

camera = cv2.VideoCapture(0)

firstFrame = None

gun_exist = False

while True:

   

    ret, frame = camera.read()

    frame = imutils.resize(frame, width = 500)

    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)

   

    gun = gun_cascade.detectMultiScale(gray,1.3, 5,minSize = (100, 100))

   

    if len(gun) > 0:

        gun_exist = True

       

    for (x, y, w, h) in gun:

       

        frame = cv2.rectangle(frame,

                            (x, y),

                            (x + w, y + h),

                            (255, 0, 0), 2)

        roi_gray = gray[y:y + h, x:x + w]

        roi_color = frame[y:y + h, x:x + w]

    if firstFrame is None:

        firstFrame = gray

        continue

    # print(datetime.date(2019))

    # draw the text and timestamp on the frame

    cv2.putText(frame, datetime.datetime.now().strftime("%m-%d-%Y %H:%M%p"),

                (10, frame.shape[0] - 10),

                cv2.FONT_HERSHEY_SIMPLEX,

                0.35, (0, 0, 255), 1)

    cv2.imshow("Security Feed", frame)

    key = cv2.waitKey(1) & 0xFF

   

    if key == ord('q'):

        break

if gun_exist:

    print("guns detected")

else:

    print("guns NOT detected")

camera.release()

cv2.destroyAllWindows()
