How do 360 cameras work ?

A 360-degree camera, also known as an omnidirectional camera or panoramic camera, captures a full spherical or cylindrical view of its surroundings. Here’s how it works:

  1. Multiple Lenses: A 360-degree camera typically consists of multiple lenses arranged in a specific configuration to capture images from different viewpoints simultaneously. These lenses may cover different angles or directions, such as horizontal, vertical, or diagonal views.
  2. Image Stitching: The images captured by each lens are then digitally stitched together to create a seamless panoramic image or video. Image stitching is a process that aligns and blends overlapping areas of adjacent images to produce a continuous panoramic view without visible seams or distortions.
  3. Panoramic Projection: Once the images are stitched together, they can be projected onto various types of viewing surfaces, such as flat screens, spherical displays, or virtual reality headsets. Panoramic projection techniques ensure that the viewer experiences an immersive and realistic representation of the captured scene.
  4. Software Processing: Advanced software algorithms are used to process the captured images and perform tasks such as image alignment, distortion correction, and color balancing. These algorithms help ensure that the final panoramic image or video is visually accurate and high-quality.
  5. 360-Degree Viewing: The resulting panoramic image or video provides a complete 360-degree view of the surroundings, allowing viewers to pan, tilt, and zoom to explore different perspectives interactively. This immersive viewing experience is often used for virtual tours, immersive storytelling, and surveillance applications.
  6. Optional Features: Some 360-degree cameras may include additional features such as built-in gyroscopes for stabilization, HDR (High Dynamic Range) imaging for improved contrast and color reproduction, and live streaming capabilities for real-time sharing of panoramic content.

What is the Fish Eye Effect?

The fisheye effect in 360-degree cameras refers to a type of distortion that occurs due to the wide-angle lenses used to capture panoramic views. This distortion is characterized by straight lines appearing curved or bent, giving the image a characteristic fish-eye appearance.

Here’s how the fisheye effect occurs in 360 cameras:

  1. Wide-Angle Lenses: 360-degree cameras typically use wide-angle lenses to capture a broad field of view. These lenses have a very short focal length compared to standard lenses, allowing them to capture a wide area in a single frame.
  2. Radial Distortion: Wide-angle lenses exhibit a type of distortion known as radial distortion, where straight lines near the edges of the frame appear curved. This distortion increases as you move away from the center of the image towards the edges.
  3. Curvature of Light: The curvature of the lens causes light rays entering the camera to bend more towards the edges of the frame than towards the center. This bending of light rays results in the fisheye effect, where straight lines become curved and objects appear stretched or distorted towards the edges of the image.
  4. Correcting Fisheye Effect: To mitigate the fisheye effect, 360-degree cameras often use software algorithms to perform distortion correction during image processing. These algorithms analyze the captured image and apply corrective measures to straighten lines and reduce distortion, resulting in a more natural-looking panoramic view.
  5. Impact on Image Quality: While the fisheye effect can create a unique and immersive viewing experience, it can also affect image quality by distorting object proportions and reducing the clarity of fine details, especially towards the edges of the frame. Correcting this distortion helps improve the overall visual fidelity of the panoramic image or video.
