Some applications have limited viewing positions for the camera. Like speed cameras above the motorway or when you have not enough space in your machine. You can improve imaging blur caused by tilted setting of the camera. A well designed scheimpflug adapter compensating the prism effects gives you sharp images. For example: taking images in ITS applications, at a conveyor belt checking fruit, grain, recycling materials, etc.
Scheimpflug principle: camera tilted to 45 degree. See below
The picture ‘With Scheimpflug correction’ has a higher MTF/CTF, this result is due to the Scheimpflug adapter.
The matching of the colours is an important engineering challenge.
