Surround view lenses are a series of ultra wide angle lenses offering up to 235 degrees view angle. They come in different image formats to match different size sensors, such as 1/4", 1/3", 1/2.3", 1/2.9", 1/2.3" and 1/1.8". They are also available in various focal length from 0.98mm to 2.52mm. All of these lenses are all glass design and support high resolution cameras. Take CH347, it support up to 12.3MP resolution. These super wide angle lenses have a good use in vehicle surround view.
A Surround View System (also known as an Around View Monitor or Bird's Eye View) is a technology used in some modern vehicles to provide the driver with a 360-degree view of the vehicle's surroundings. This is achieved by using multiple cameras mounted on the front, rear, and sides of the car, which provide a live video feed to the car's infotainment display. The cameras capture images of the vehicle's immediate surroundings and use image processing algorithms to stitch together a composite, bird's-eye view of the car's surroundings. This allows the driver to see obstacles, pedestrians, and other vehicles from a bird's-eye view, which can help them maneuver the car in tight spaces or while parking. Surround View Systems are typically found on high-end vehicles, although they are becoming more common on mid-range models as well. They can be particularly useful for drivers who are new to driving or who are uncomfortable with tight maneuvers, as they provide a greater level of visibility and situational awareness. The lenses used in these systems are typically wide-angle lenses with a field of view of around 180 degrees. The exact type of lens used can vary depending on the specific surround view system and the manufacturer. Some systems may use fisheye lenses, which are ultra-wide-angle lenses that can capture a hemispherical image. Other systems may use rectilinear lenses, which are wide-angle lenses that minimize distortion and produce straight lines. Regardless of the specific lens type used, it is important for the lenses in surround view systems to have high resolution and image quality in order to provide a clear and accurate view of the vehicle's surroundings. This can help drivers navigate tight spaces and avoid obstacles while parking or driving in congested areas.
