How to fix OpenCV Numpy Error, object is not iterable

Asked 2019-Mar-26 at 01:06

I'm following a guide to develop a motion detection security feed and have run into an issue. The author of the tutorial had no issues, but I do.

'''The full code can be found here: https://github.com/ncorbuk/Python-Motion-Detection-system/blob/master/motion_detection.py '''

I have already tried the option of adding,

" for c in cnt or []: " - This got me further into running the application where I could see the camera screens, however as soon as motion is detected the application crashes and provides the following numpy error:

In Opencv4.0, findContour() returns only 2 values, contours and hierachy. So in the line 57 in motion_detection.py you have to change

cnt = cv2.findContours(dilate_image.copy(), cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)[1]

cnt = cv2.findContours(dilate_image.copy(), cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE)[0].

Detect Basic Change in Video using OpenCV

Asked 2018-Jan-11 at 01:07

Trying to recreate a basic change detection program I got from a great blog done by Adrian Rosebrock (if looking to get into python and OpenCV go here). The code was designed in python and I am trying to convert it to C++. You can find the blog post here. My struggle is with the absdiff(firsFrame, gray, imageDifference) as every iteration of the loop has firstFrame and gray being equal. I think the problem is either where I initialize firstFrame = gray but I did a cout check to see how many times it is hit so not sure. Here is code:

...

ANSWER

Answered 2018-Jan-10 at 15:42

Some to be improved:

firstFrame = gray => gray.copyTo(firstFrame)

you define firstFrame and gray at the same line, then after do firstFrame = gray, they share same data memory. So every time they are the same.
Skip some frames.

As the camera just starts, so the first frame is not that stable, you should skip some frames(like 10 frames).
cv::Scalar <==> tuple

In C++:

cv::Scalar(b,g,r) <==> tuple(b,g,r)

(b,g,r) ==> r

QUESTION

How to detect moving object on a moving conveyor using opencv

Asked 2018-Jan-03 at 11:58

I'm building a grading system for crabs. In this system, the animals (crabs) are placed in a moving conveyor and I need to identify dead or alive animals by detecting its motion based on images captured by a camera on this conveyor. The color of conveyor belt is black.

As the conveyor is always moving, so I can't apply methods using stationary camera like here. Does anyone have a suggestion about motion detection of the animals in this case using opencv? I can use more than one camera if it's necessary. Thanks.

...

ANSWER

Answered 2018-Jan-03 at 11:32

Well, the most obvious answer is: 1) adjust the pictures of the conveyor in the different periods of time so that they become of the same area. 2) watch which ones of the crabs have different poses (like, "substract the images") - different regions (pixels) mean that there happened a motion.

If using a tracking - well, you should train your classifier to watch the crabs, and than compare the regions of crabs in a same way. But i think it's too complicated for your particular issue.
