  previous post : Obstacle detection using Laser and image processing on LOGI-Bone FPGA Camera Data ProcessingThis is part 1 of a 2 part article which details interfacing a camera to an FPGA, capturing the data and then processing the data using a pipelining technique.  One of the many strengths of using an FPGA is the speed and flexibility it gives to processing data in a real-time manner.  An interface to a camera is a good example of this case scenario where cameras output v ...
The Problem  Typical obstacle detection on low cost mobile indoor robots are usually performed using a variety of sensors, namely sonar and infrared sensors. These sensors provide poor information that is only able to detect the presence of a reflective surface in the proximity of the sensor and the distance from the surface. While in most cases it’s enough to navigate a robot on a crowded floor, it does not help the robot for other tasks and adds more sensors to the robot. This does ...
