This paper proposed a method of real-time route planning for UAV based on model predictive control (MPC) and threat gain fuzzy controller (TGFC). First the model of three-dimensional route planning of UAV was built by MPC, including complex constraints. Then the TGFC was designed based on fuzzy control theory, in order to make UAV escape from the sudden threat quickly. Finally the route was calculated...
A new aviation proactive maintenance support system was put forward based on the Beidou satellite data link. The “Air-Ground” two-direction data processing method was adopted to carry out the on-line interpretation of flight parameters, the proactive maintenance support and the real-time operation of the safety monitoring system. The basic condition of proactive maintenance support, aircraft real-time...
In this work, a fast shape searching face alignment (F-SSFA) algorithm based accelerator is proposed to achieve real-time processing. Firstly, a learning based low-dimensional SURF feature is introduced to reduce the computation cost in the cascaded regression. Then the Euclidean distance and shape affine transformation are utilized to accelerate the shape searching procedure. F-SSFA therefore greatly...
We propose a graph matching based approach to identify multiple people in an indoor localization system by using the infrastructure camera along with microphone and speaker in a smart phone. Given a frame captured by the camera, an attributed graph is composed by considering each person in the frame as the vertice and the distance between people derived from the locations provided by the camera as...
An online health monitoring system (OHMS) was tailor-made and implemented for structural health monitoring (SHM) of train structures. A sensor network made up of miniature piezoelectric wafers was configured on the bogie frames of China's latest high-speed train model. Ultrasonic guided waves were generated through the sensor network, and a variety of signal features were retrieved and fused by the...
A programmable real-time system based on DSP and FPGA for the image object tracking is proposed. The high-performance fixed-point DSP TMS320DM643 as kernel processor is suitable for processing video signal. This paper presents in detail the work flow of the solution, the function and principle of components, such as preprocessing and OSD FPGA, the external memory interface, the transport and control...
Many complex distributed real-time applications, monitoring and controlling the external environment, require sophisticated processing and sharing of an extensive amount of data under critical timing constraints. We present adaptive real-time publish-subscribe (RTPS) messaging service for distributed real-time applications, and four primitives are defined for expressing the adaptive RTPS. Furthermore,...
