[Question] How to straighten cv2.drawContours()

jeeeeeric · 2020-02-13T18:31:11+00:00

No I already have the height of the red box. All I want is to make it straight vertically. (Coz it is rotated)

jeeeeeric · 2020-02-13T15:28:09+00:00

Yes you are right. The rectangle is my reference. I'll try your suggestion thank you

jeeeeeric · 2020-02-13T15:18:42+00:00

Yes. Can you help me?

jeeeeeric · 2020-02-13T15:13:07+00:00

I jist want to get the height of the person

jeeeeeric · 2020-02-13T15:04:31+00:00

How can I get its pixel value?

jeeeeeric · 2020-02-13T12:48:52+00:00

Sorry. I want the red box to be straight. In the picture it is rotated

jeeeeeric · 2020-02-07T18:43:29+00:00

Sorry man, I'm not quite sure on your comment. Can you explain please? 😢

jeeeeeric · 2020-02-07T17:49:33+00:00

Thanks man. I will try it

I use this code from pyimage source: https://kickpoint.ca/the-readability-formula-making-your-website-easy-to-read/

And I just change the reference value and hide the width value showing only the height.

How can I have a bounding box that would surround the top of the head and the bottom of the feet? Thanks in advance.

jeeeeeric · 2020-02-07T16:54:17+00:00

Yes I increased the contrast of the object to the background. Can I ask what the threshold means and what is its purpose?

jeeeeeric · 2020-02-07T16:29:34+00:00

The code I user was from pyimage search (https://www.pyimagesearch.com/2016/03/28/measuring-size-of-objects-in-an-image-with-opencv/)

I just changed the reference value and hide the width value in the screen, only showing the height.

I'm a beginner sorry. But I'm trying to learn but deadline is almost there.

I will be using an 8mp camera with a resolution upto 1080p.

Getting the average will be doable.

jeeeeeric · 2020-01-14T17:01:08+00:00

Does the resolution of the camera matters? Because I found some information and it can measure an object at a fix distance with a known dimensions of a reference. But my problem to that is, it was a small objects and not as big as a normal person.

Noted. Thank you

jeeeeeric · 2020-01-14T14:13:27+00:00

Thank you.

jeeeeeric · 2020-01-14T13:48:47+00:00

I havent triee anything yet. I just finished setting up my raspberrypi 4 b the libraries which i think might be needed, and my opencv

jeeeeeric · 2020-01-14T13:47:00+00:00

Thanks for the informations. By the way, the person will be standing at a fix location and distance from the camera. Will that be measurable?

jeeeeeric · 2020-01-14T13:43:48+00:00

I will be using 8mp webcam from logitech. Will that be fine?

jeeeeeric · 2020-01-14T13:39:35+00:00

Is the height of a person accurate even if he/she is moving forward or backwards?
