The Art Of Electronics

Today we will discuss how you can find the distance of an object from the camera using python OpenCV. Check out the video below. Before we continue, you should know how to detect a colored object. Click this  link  to check out my previous blog on object detection and tracking. I hope after checking out my previous blog, you are able to write your own code to detect and track objects. We will take forward the Object detection and tracking code to find the distance of an object from the camera. So let's start. Let us first understand the principle using which we will find the distance of the object from the camera. Principle:- As the object moves farther away from the camera, the Y-axis coordinate decreases. This simply means that, if your object is near to the camera, the Y-axis coordinate will be very large. As you move the object farther from the camera, the object will appear to move above in the image and thus decreasing the Y-axis coordinates proportionately. Th...

We will take forward the Object detection and tracking code to find the distance of an object from the camera. So let's start. Let us first understand the principle using which we will find the distance of the object from the camera. Principle:- Area enclosed by the contours of an object decreases as the object moves farther from the camera. This simply means that, if your object is near to the camera, the object will appear bigger. Thus the pixel area occupied by the object will be very large. As you move the object farther from the camera, the object size in the image will start to d...
