　Collaborate simulators and camera sensors
"UC-win/Road Camera Sensor Base Plug-in Option" can generate distorted images on UC-win/Road that is like shot by a fisheye lens. It supports the transmission of camera information by the cluster system, and the camera sensor simulation linked with simulators can be performed.
　Difference of image between 3D CG and camera
Perspective projection that draws in the range of the square pyramid with the viewpoint position at the vertex is usual for 3D CG rendering, and this method is also used for the rendering in UC-win/Road. As for actual cameras, the central projection that is the same method as the CG perspective projection is general. However it doesn't always match the perspective projection because these lenses also have distortion in some degree.

Moreover, as for the fisheye lens that a wide view angle can be shot with, the used projection method is not the central projection method, but the equidistance projection that the distance from the center is proportional to angle, and the equisolid angle projection that the area from the center is proportional to solid angle. This plug-in has been developed in order to achieve the simulation of the shooting by a real camera on UC-win/Road.		 Click to enlarge the image.

　Function overview
This plug-in renders all directions around the camera in UC-win/Road, and creates simulation result image accordingt to the camera parameter in the result. As for the fisheye lens' projection method, it supports "Equidistance projection", "Equisolid angle projection", "Stereographic projection", and "Orthogonal projection". From the information of "number of pixel", "cell size", "focus distance", and projection method, it calculates and arranges the height of the image and the camera direction at the sensor position and generates camera images.

More various camera simulations are available by defining the angle and image height processing by polynomial, or the distortion table file by CSV file, in addition to the setting by these projection methods and parameters. This plug-in can be utilized for a lot of ways such as R&D of camera sensors and examination of location and performance of security cameras.		 Click to enlarge the image.

　Linkage with cluster system
In a cluster system, this plug-in supports transmission of camera information from master to clients. Information that can be sent is the drawing parameter information by camera sensor plug-in as well as the relative coordinates from objects or traveling vehicles and the absolute coordinates kept as the camera position in UC-win/Road. This enables the simulation of the camera sensor that is attached to the traveling vehicle performed on the cluster client side at the time of driving simulation by using the cluster system.
　Customization development by applying this plug-in
When you want to simulate cameras or sensors, you can utilize the customization development based on this plug-in. It can be used as a development base according to a variety of ways of use such as developing a function to generate simulation image of the actual camera and the simulation of laser sensor using depth information.

It would be appreciated if you introduce the camera sensor base plug-in as the development base including sensor simulations, and make a use of UC-win/Road.		 Click to enlarge the image.
