High-speed transmission of aerial images based on PTP protocol

In order to reduce the mount of image data, enhance the speed of image transmission and to realize the high-speed transmission of aerial images, a high-speed and feasible method for image transmission was researched. On the basis of the Picture Transfer Protocol(PTP), an image transmission system of aerial digital camera was presented by using the JPEG image compression algorithm and the multi-threaded transfer mode of file stream. The design scheme of the system was introduced and its feasibility was proved. Experiment results demonstrate that the image average transfer rate is 53.641 Mb/s and error rate is 0.00%, which shows that this system not only guarantees a good data primitiveness and prevents data loss, but also reduces the data path blockage effectively.
