Object Distance Calculation - Method 1 | Python | OpenCV

In this video, you will learn about how to find the distance of an object from the camera using Opencv library. This method is based on the principle that the contour area of an object decreases as the object moves farther from the camera.

Simply explained, thank you! There's very little content about this compared to a lot of OpenCV topics.

Thanks a lot clever man. Inspired by your idea I was able to use my camera to measure level of a tank instead of using an inaccurate HC-SR04 sensor. I am using a 6th grade polynomial function. All this knowledge in one video...I am amazed

[kaanankalyan]

very simple and sensible method, thank you !

Great Vibhor Meshram keeps rocking!!!....

Awesome sir.. initially i know that we have to calculate distance from area but from the video i learnt that how to generate equation from observation measurings. Thats cools

[muhammadsaad]

Thanks, wonderful tutorial for beginners like me easy to understand.

[alenninan]

hii, will the ball distance be measured at an angle also ?

[sohamhingne]

Hello sir. I am so inspired by this! I hope I can learn more from you! If only there was a way I could learn from you in

[saifkhan]

i just want the detailes means how you calculate the distance of object ?

[gyrotmmaster]

hello sir...may i know how you calibrate...im mean that data you take ...then where you put it??..very thanks if you could share...

[hsthings]

Bro can you help doing the same for human iris bro?, if you can help me track the iris that would be great help please bro.

How u find the manual distance(cm) from area?

[samirelzein]

You didnt need the calibration, you can exploit the proportionality between 2 frames, at 2 distances.

Hello sir...the code is really awesome...need your small guidance regarding one of my project where i am trying to find the distance between the camera to the driver's seat so that based on the minimum distance i can determine who is the driver..I am really struggling finding the perfect solution for it..pls help..waiting for your response

[SAINIVEDH]

Does this work on any object(cars) given we know the area using segmentation models. Can we try building traffic collision system with this POC ?!!. Please shed your thoughts

[sathishbabu]

hello sir...this code is really awesome...., i'm doing a project related to object distance...
could u please explain about these values


i know u r calculating to find contour area for ball..., but i want this for humans


what is 153, 119, 212, 255 here?


lb = np.array([153, 119, 212])
ub = np.array([255, 255, 255])


how u find this values 0.0067, 83.487
is there any formula for distance?
distance = 2*(10**(-7))* (area**2) - (0.0067 * area) + 83.487


i'm trying to apply this code to haarcascades...., so that y i want to remove all those stuff...., & surely i wanna find distance of detected haarcascade object....


how to find distance of a person...?
please help me sir...this is my academic project....i wanna do something....

[electroware]

Bro I just need to know the x, y axis of the object how

[hamzaaa]

hello, i tested your code but it didn t work

[akshayhazare]

Sir need your help for project. willing to pay for it. Really need your help and its really urgent. Its for university submission.
