Hi.
I made mipi csi-2 data using Lattice fpga.
This data is test video.
Wave of data is as follows.
https://www.dropbox.com/sh/3lnwk6b3jjsxyqj/AABjU9ypGk4YLKtWXO9RTq2Ka?dl=0
I would like to use this to check the MIPI image on the Jetsn tx2.
I checked the image of the Jetson onboard camera with the program below.

#!/usr/bin/env python
import sys
import argparse
import cv2
import numpy as np
def parse_cli_args():
parser = argparse.ArgumentParser()
parser.add_argument("--video_device", dest="video_device",
help="Video device # of USB webcam (/dev/video?) [0]",
default=0, type=int)
arguments = parser.parse_args()
return arguments

def open_onboard_camera():
#return cv2.VideoCapture("nvcamerasrc ! video/x-raw(memory:NVMM), width=(int)1280, height=(int)720, format=(string)I420, framerate=(fraction)30/1 ! nvvidconv ! video/x-raw, format=(string)I420 ! videoconvert ! video/x-raw, format=(string)BGR ! appsink")
return cv2.VideoCapture("nvcamerasrc ! "

if video_capture.isOpened():
windowName = "JetsononboardDemo"
cv2.namedWindow(windowName, cv2.WINDOW_NORMAL)
cv2.resizeWindow(windowName,1280,720)
cv2.moveWindow(windowName,0,0)
cv2.setWindowTitle(windowName,"Jetson onboard Demo")
showWindow=1 # Show all stages
while True:
if cv2.getWindowProperty(windowName, 0) < 0: # Check to see if the user closed the window
# This will fail if the user closed the window; Nasties get printed to the console
break;
ret_val, frame = video_capture.read();
hsv=cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
if showWindow==1: # Show Camera Frame
displayBuf = frame
elif showWindow == 2: # Show Gray Frame
displayBuf = hsv
cv2.imshow(windowName,displayBuf)
key=cv2.waitKey(10)
if key == 27: # Check for ESC key
cv2.destroyAllWindows()
break ;
elif key==49: # 1 key, show frame
showWindow=1
elif key==50: # 2 key, show Gray
showWindow=2
else:
print ("camera open failed")
if __name__ == '__main__':
arguments = parse_cli_args()
print("Called with args:")
print(arguments)
print("OpenCV version: {}".format(cv2.__version__))
print("Device Number:",arguments.video_device)
if arguments.video_device==0:
video_capture=open_onboard_camera()
else:
video_capture=open_camera_device(arguments.video_device)
read_cam(video_capture)
video_capture.release()
cv2.destroyAllWindows()
I want to check how the MIPI data is coming in from the Jetson board.
Is there a way to check this out?
