Key Features

With the creation of a virtual 3D space around a vehicle comes a myriad of challenges to solve and continue on improving. To customers, one common basic issue is the one in the physical realm - where the target vehicle is of specific dimensions and going through a multitude of changing environments.
Therefore Xylon has developed a flexible and robust system that enables users to change a variety of hardware, software and camera positioning specifications on a case by case basis.

Surround View can adjust to the number of cameras used, the types of lenses used and the proper mathematical calculation to adapt to these differences and deliver a stable and reliable product. For this purpose Xylon has created our own user-friendly and graphically representative software suite used for set up and modification of certain camera parameters – called logiBUILDER . It enables users to create, add or create modes to adjust the camera parameters to their needs via an easy to use graphical interface. It is accompanied by the logiOWL Vehicle Self Calibration application, an automatic end-of-line camera calibration suite that can run fully embedded in the target vehicle and enables full vehicle multi-camera calibration in as little as 10 seconds.

Some of the key features, each developed to tackle a challenge that was discovered through the practical use of our Surround View implementations. Users also retain the ability to turn on and off each feature depending on their needs and requirements in each scenario.

Real-Time Dynamic Stitching

In the overlap zones of cameras, there is a distinct possibility of a blind spot occurring at specific distances from the vehicle. To combat this, Xylon has implemented real-time regions angles changes or dynamic stitching, which enables users to quickly and on-the-fly modify the overlap zones calculations using alpha masks. By relying more on one cameras field-of-vision-rather than the neighbouring, users can spot incoming vehicles in the overlap zones at a farther distance. One such practical example can be seen below in our Surround View showcase video at 03:15.

Color Contrast Equalization

When using a top down view in Surround View, users may notice the differing color contrast or brightness levels on each sector. Despite this at first looking like wrong and an issue with the system, in reality it is due to the effects of the suns position and corresponding shadows. To compensate for this when using the top down view, Xylon has developed this feature to produce a consistent visual representation across all regions, especially for overlap zones that may experience.

Real Time Bowl Shape Changes

As with real-time dynamic stitching, through numerous years of experience with developing and integrating Surround View solutions Xylon has identified the benefits of having a real-time changeable representation of the space surrounding the vehicle. The "so-called" bowl of 360 degree space surrounding the target vehicle can be shaped as anything from a picture perfect circle to various ellipsoidal shapes. By being able to the change the bowl's radius in both positive and negative directions in both the X and Y axis, users can be change the bowls shape to have a farther view into either the space on the sides of the vehicle, in the front-back axis of the vehicle or equally in all directions.

Blindness Detection

Using Xylon’s logiDIRT Blindness Detection IP Core is used to determine whether pictures from
camera are blurred by dirt, snow or water. By implementing this capability as a separate IP Core, it is far more configurable and faster than purely software-side solutions. The usage of the IP Core can be toggled and decided for each camera individually. Frames from every camera is cut into regions of interest (ROI) where every region is individually detected for blur. User can also choose manually ROIs which will be used for blindness detection modifying a single text file.

Model Transparency

Users can in real-time turn the transparency of the target vehicle's model on and off, depending on the needs of the situation. The vehicle model itself is easily changeable and modifiable by the user.
