A Inventive Method for Door Detection on FPGA Using Sobel Edge Algorithm

Now a days door detection is a key factor in robotics, especially physically disabled people or old age or senior citizen. So, it necessary to improve an assistive device for detecting door. The proposed work includes the way of robot is going to identify the door by using Sobel edge detection algorithm through image processing, once the image of the door is captured then robot move inside the door or outside the door as per the requirement. The image will be captured through camera which is fixed to the robot whenever there is an edge like structure while moving from one room to another room. This Sobel edge algorithm is implemented on Xilinx FPGA Zed board with 100Mhz frequency.
