Abstract:
Advanced driver-assistance system(s) (ADAS) are more prevalent in high-end vehicles
than in low-end vehicles. Wired solutions of vision sensors in ADAS already exist, but are costly
and do not cater for low-end vehicles. General ADAS use wired harnessing for communication;
this approach eliminates the need for cable harnessing and, therefore, the practicality of a novel
wireless ADAS solution was tested. A low-cost alternative is proposed that extends a smartphone’s
sensor perception, using a camera-based wireless sensor network. This paper presents the design
of a low-cost ADAS alternative that uses an intra-vehicle wireless sensor network structured by a
Wi-Fi Direct topology, using a smartphone as the processing platform. The proposed system makes
ADAS features accessible to cheaper vehicles and investigates the possibility of using a wireless
network to communicate ADAS information in a intra-vehicle environment. Other ADAS smartphone
approaches make use of a smartphone’s onboard sensors; however, this paper shows the application
of essential ADAS features developed on the smartphone’s ADAS application, carrying out both
lane detection and collision detection on a vehicle by using wireless sensor data. A smartphone’s
processing power was harnessed and used as a generic object detector through a convolution neural
network, using the sensory network’s video streams. The network’s performance was analysed to
ensure that the network could carry out detection in real-time. A low-cost CMOS camera sensor
network with a smartphone found an application, using Wi-Fi Direct, to create an intra-vehicle
wireless network as a low-cost advanced driver-assistance system.
