Fisheye Dewarping Leave a comment

When it comes to video surveillance, it’s extremely important to capture all areas of a property for protection. However, traditional security cameras are prone to having blind spots. Blind spots are areas that the security camera cannot capture because they are out of the camera’s view. To remedy this issue, some security cameras utilize a lens that is called a “fisheye” lens. These lenses are useful because they are able to capture a view of up to 360º, which reduces the amount of blind spots. However, the image that the fisheye lens captures tends to be distorted and requires dewarping for best results.

What is Dewarping?

Dewarping is the process of correcting images from fisheye cameras. Fisheye cameras are able to capture a wider view, but the images that are produced tend to look curved. The effect is interesting to look at, but is not really ideal when it comes to surveillance. For better accuracy, surveillance footage should mimic the clarity from human sight. Dewarping is needed in order to adjust the images to look like the images captured from traditional security cameras.

Why Use This?

Fisheye cameras are extremely useful in order to cover more ground with a single camera. Users are able to to get a panoramic view of an area without having to move the camera around. By using fisheye cameras, you are able to use less cameras and this eliminates the need for special PTZ cameras. But when it comes to surveillance footage, the more clear the image, the better. Dewarping allows you to enjoy the benefits of fisheye cameras, but without the con of distorted images.
