QUESTION

I have a list which copies itself or appends itself every time I run my program and I really don't understand (python with opencv)

Asked 2021-Jun-01 at 18:35

I'm actually coding a Multitracker with Opencv using a CSRT tracker. (I used a online code and modified it as I need, here is the source: https://learnopencv.com/multitracker-multiple-object-tracking-using-opencv-c-python/ ) Every time a bounding box is 'updated' its coordinates are added to a list.

For every bbox (bounding box) I have to lists, one for the x and y coordinates of the top left corner of the bbox, and an other one for the x and y coordinates of the bottom right corner. (Those lists are respectively called p1 and p2.)

I have done almost everything that I want, but the p2 list of the bbox 1 don't stop copying itself or something like in the p2 list of the third bbox, and it don't depend of how much bbox exists. Note that I don't want any comments about improving it or optimizing it I don't care about it. Note too that the program is made to run with up to 6 bbox, and it's normal I don't need more but the program can run with 1, 2, or least that 6 bbox if I want.

If I'm lucky it's a stupid error, but I can't get it, so maybe that looks from other peoples on it may find it better than I can! ^^

Here is my long, unoptimized and ugly program! (And thanks if you help me!):

Well after reading it almost 3 times I understood. Using lists which had siblings names wasn't a good thing to do same if I can't do it in an otherway, I was just printing an other list x3

QUESTION

Understanding OpenCV homography at a minimum of points

Asked 2021-May-13 at 07:21

I am quite intrigued by the idea of a homography and try to get it to work at a minimal example with python and OpenCV. Yet, my tests do not pass and I am not quite sure why. I pass in a set of corresponding points into the findHomography function according to This and then multiply the homography matrix to receive my new point.

so the idea behind it is to find the planar coordinate transformation and then transform the points with

X' = H@X

where X' are the new coordinates and X are the coordinates in the new coordinate frame.

Here is some minimal code example:

For the error message "Expected 2 columns, but found 1 columns only." try to fix the format of your CSV file, open the file in a text editor of your choice (such as Cloud Shell, Sublime, Atom, etc.) to inspect the file format.

When opening a CSV file in Google Sheets or a similar product, you won't be able to format the file properly (i.e. empty values from tailing commas) due to limitation on the user interface, but in text editors, you should not run into those issues.

If this does not work, please share your CSV file to make a test with your file by my own.

How to replace scipy.spatial.distance with np.linalg.norm in Python

Asked 2020-Apr-03 at 10:47

I am following this tutorial to implement object tracking for my project - https://www.pyimagesearch.com/2018/07/23/simple-object-tracking-with-opencv/

Method is to find centroids of detected objects in the initial frame, and then calculate the shortest distance to the other centroids of detected objects that show up on the next frame. Assumption is that a centroid that is closest would be a same object.

In the tutorial -

You can use Numpy broadcasting to create a distance matrix.

Read about it here and here.

The basic idea is:

Stack (reshape) your centroids as (1, n, 3) and (n, 1, 3) where the last dimension with shape 3 is (x,y,z). Then subtract the arrays and use np.linalg.norm to calculate the distance along axis ... hm ... probably the last one. That should yield a square (n,n) distance matrix.

I have a Django + Python application. I have a python script that takes requirements as command line options.

The issue for me is that when I try to put in the command line arguments the script fails to execute. When I take out the command line arguments, it runs fine. I need those command line arguments.

I am using node JS with Python Shell to execute the python script when the button is clicked in the django HTML front page.
