I am currently working on a project which makes use of a Raspberry Pi and its Camera Module v2.1. I need to scan some barcodes with the camera of which I am using the OpenCV and pyzbar libraries. I am running into some trouble with the image that OpenCV is returning, example below: Image returned ..
I am trying to import pytorch on the Nvidia Jetson Nano 2 and I am facing the following issue. The version of pytorch that I am using is 1.10.0 with torchvision 0.11.1 and torchtext 0.6.0 (if that is relevant) I have tried the following: Changing the order of the imports export $LD_PRELOAD=’/home/msc/.local/lib/python3.6/site-packages/torch/lib/libgomp-d22c30c5.so.1′ followed by source ..
I made a python code where it will launch the pi camera and I can use buttons to record a video for 30 seconds or take pictures. In this python code, I mixed in another python script where I can launch a thermal imaging window with the press of a button and close it with ..
I’ve tried many tutorials and installation to use the rapsberry 4 picamera with Python I’m using Picamera library and everytime I use this simple script or any picamera script to try the camera I got this error message: mmal: mmal_component_create_core: could not find component ‘vc.camera_info’ Traceback (most recent call last): File "/home/pi/Desktop/ex.py", line 6, in ..
So basically I have the piCamera attached with my RPi, I repeat the PiCamera not an USB webcam. and want to read frames from it, I am actually able to read the frames but with some weird behavior. from imutils.video import VideoStream CASE 1: if I use vs = VideoStream(src=0, resolution = (640, 480)).start() it ..
I’m trying to capture images with my RaspiCam v2. I have a very specific setup and specified all camera parameters that i need to get a good image quality. I figured them out using a separate python script caputring the image with following line: camera.capture(‘filename.jpg’). In my actual program i want to capture the image ..
i have a working picamera on my raspberry, i would see it into a tkinter’s window using python 3. following my code: from picamera import PiCamera import RPi.GPIO as GPIO from time import sleep CAM=PiCamera() CAM.rotation=180 CAM.resolution=(1920,1080) CAM.framerate=15 CAM.start_preview() CAM.preview.fullscreen=False CAM.preview.window=(0,0,300,300) GPIO.setmode(GPIO.BCM) GPIO.setup(18,GPIO.OUT) S=GPIO.PWM(18,50) S.start(10) time.sleep(1) GPIO.cleanup() GPIO.setmode(GPIO.BCM) GPIO.setup(4,GPIO.IN) Source: Python..
I am taking multiple white light images in a row that I want to split into RGB images later on due to time constraints for my application. I currently save the raw RGB image as a .data but cannot figure out how to read the file back into an array to allow me to manipulate ..
I have made a raspi0 PIR cam and am trying to get it to write to my network storage device. The .py writes to the drive but just keeps re-saving over the same file unless I ctrl C and manually restart. from picamera import PiCamera import time from time import sleep import os import sys ..
I am trying to do some real time computer vision work with picamera, raspberry pi 4b, and opencv and have realized that the picamera takes a nontrivial amount of time to actually capture an image, even when using the video port. For the python code below I am getting capture times of ~0.1-0.05s regardless of ..
