Prototyping a composite view for park assist cameras in automotive vehicles

Abstract: In this thesis two prototypes, based on separate implementations of a Park Assist Camera, was developed. The purpose was to investigate the possibility of presenting a composite view, where the first view shows the surroundings of the car from a bird’s-eye view and the other view shows the rear camera. The first prototype was based on Volvo Car Corporations flavour of Android OS, where the performance of the prototype was limited by a component responsible for processing frames from the four cameras into a single,continuous, stream. The second prototype, based on a computer running Linux, used OpenCV to process the camera streams due to the absence of aforementioned component in the first prototype. To evaluate the performance of each prototype, the amount of frames being rendered each second was measured as well as the perceived latency. Both prototypes presented almost identical results regarding perceived latency, while the first prototype performed better in regard to frames per second. However, the second prototype was unexpectedly suffering from a low frame rate which was not thoroughly investigated due to time constraints.
