Hexa Cam: An FPGA-Based Multi-view Camera System

Accurate perception information of the surroundings is a desirable feature in any cyber-physical system for autonomous robotics. Besides, providing a cost-wise solution to this need, is also useful for developing other kinds of applications such as mapping, decision-making, self-localization, among others. In this work, we present and benchmark a cost-effective camera device with six image sensors attached to a custom built FPGA board. The perception information is delivered on the host side, thanks to a HOG based object detector executed on the GPU. Our conclusion is that the low cost prototype is able to acquire and extract the perception data in 9.41 frames per second.
