Recently, I do my final project for my bachelor degree with Beaglebone Black.
I got problems is: 1: when I run python program like following command with pyhton using the Ubuntu (XFCE Desktop) connect with Beaglebone Black
!/usr/bin/python
import cv2.cv as cv iport time
cv.NamedWindow("camera", 1)
capture = cv.CaptureFromCAM(0) cv.SetCaptureProperty(capture, 3, 360) cv.SetCaptureProperty(capture, 4, 240)
while True: img = cv.QueryFrame(capture)
cv.Smooth(img,img,cv.CV_BLURK,3)
hue_img = cv.CreateImage(cv.GetSize(img), 8, 3)
cv.CvtColor(img,hue_img, cv.CV_BGR2HSV)
threshold_img = cv.CreateImage(cv.GetSize(hue_img), 8, 1)
cv.InRangeS(hue_img, (38, 120, 60), (75, 255, 255), threshold_img)
cv.ShowImage("Color Tracking", img)
cv.ShowImage("threshold", threshold_img)
if cv.WaitKey(10) == 27:
break
and then, I run this python file use "./name.py"
**it show : init done OpenCV Error: Bad argument (Array should be CvMat or IplImage) in cvGetSize, file /home/ubuntu/finalproject/(this is my opencv directory)
opencv-2.4.7/modules/core/src/array.cpp, line 1238 Traceback (most recent call last): File “./example.py”, line 16, in <module> hug_img = cv.CreateImage(cv.Getsize(img), 8, 3) cv2.erro: Array should be CvMat or IplImage**
Should I re-install OpenCV on my Beaglebone Black Board, or reset something?
Thank you
