Deployment
                  In final working prototype of the Road Crossing Assistant,
                  which can be used by blind people in real time, we have
                  deployed our single frame cnn model on Nvidia Jetson Nano B01.
                  We converted our pretrained TensorFlow model into a TensorRT
                  model to optimize the processing power and achieve low latency
                  with high throughput. The throughput obtained by TensorRT
                  model is 8 fps as compared to 3 fps by simple TensorFlow
                  model.

                    Deployment workflow
                  
                  
                    
                        Jetson Nano will run the pre-trained TensorRT model on
                        real-time video stream (obtained from the camera module
                        attached to it) and predict whether it is safe to cross
                        the road seen in the video stream. It will also control
                        the audio output of headphones to communicate with the
                        user through simple audio commands.
