Reading video with opencv python Raspberry pi

[Soufiane Tal]

Hello everyone, I have my flir lepton connected to GPIO pins in Raspberry pi. I can't read a video. I can take a picture with the written code by pylepton.
Does anyone know how I can read the video?
Here is my code:

import numpy as np

import cv2

from pylepton import Lepton

cap = cv2.VideoCapture(0)

while (True):

    ret, frame = cap.read()

    cv2.imshow('frame', frame)

    if cv2.waitKey(1) & 0xFF == ord('q'):

        break

cap.release()

cv2.destroyAllWindows()

Thank you,

Soufiane

Hi, have a look here: https://github.com/groupgets/pylepton/blob/master/readme.md and here: https://github.com/groupgets/pylepton/blob/master/pylepton_capture

essentially, you need to be getting the image from Lepton(device).capture() instead of a VideoCapture interface (which is provided by OpenCV).

Hey I am also using set code, but I cant take a picture. The main Lepton code seems to get stuck in a while loop and if I remove the loop I just end up getting black images. Please let me know if you changed the code in any way to make it work.

What I did is I got a purethermal breakout board that is connected by USB, therefore I interact with my lepton as a webcam which makes my life super easy.

You can also use the v4l2lepton program in the LeptonModule GitHub and this will make the Lepton appear as a standard webcam using the gpio breakout board.
