Optical flow is a key problem in computer vision with tremendous potential applications in many fields, such as action recognition, autonomous navigation and manipulation. In this paper, we propose a dense optical flow estimation approach for objects of interest. In order to improve the accuracy of the optical flow estimation, the intensity and depth data from the RGB-D sensor are used for doing object segmentation. Afterwards, a homography based method assuming the surface to be planar is applied to obtain dense optical flow for each segment. Several experiments have been performed to evaluate the proposed method. The results demonstrate the validity of our approach.

In order to solve the problem of stability control of moving mass reentry vehicle, a backstepping sliding mode control law based on standard backstepping control theoryis designed. Taking the perturbation of the aerodynamic parameters as the uncertain factors, the vehicle rolling angle and rolling angular velocity dual-loop sliding mode controllers are designed respectively. The virtual control of the angular velocity and the displacement command of sliding module are obtained. In the case which upper bound of the uncertainty is unknown, the adaptive method is used to design the approaching law parameters, in order to compensate for the uncertainty, and the stability of the closed-loop system is proved based on the Lyapunov function. The simulation results show that the method is effective and the tracking error is less than 0.4%.

Aiming at the positioning and navigation system of indoor mobile robot, a fuzzy control method of indoor location navigation based on UWB communication technology is proposed. Firstly, based on the UWB radio signal, the mobile robot localization information is obtained by the twice triangular centroid localization algorithm, and the reactive fuzzy controller is used to realize the local path planning. An improved contour following method is proposed to make the mobile robot get out of the trap area quickly and reach the target. This method can effectively drive the mobile robot to reach the target in a complex and unknown environment with reasonable path. Finally, a fourwheel indoor mobile robot is taken as an example in the indoor environment of 10m × 10m. The experiment proves that the method can effectively drive the mobile robot to reach the target point in the unknown environment with the better path.

Particle Impact Noise Detection is one of the most important methods in detecting remainders within relays before they put into use. The activation effect of relay remainders is the core attribute for PIND impact test condition, and it can directly affect the detection success rate. This paper analyzes the restraint model of relay remainders, and then presents an analysis method on impact activation process based on finite element simulation. Meanwhile, the influence of the impact test condition on the activation effect is also analyzed, and the key factors influencing the activation effect in impact test condition are given.

In this paper, the high-frequency, microscopic surface topography of precision optical components is analyzed. The surface profile of a precision optical component is measured by using a high-precision contacting profilometer. Visualization analysis software of mixed-language programming based on Matlab and LabVIEW is designed. Multiresolution decomposition for the sampled signals using the wavelet packet is performed and the high-frequency microscopic surface topography of the measured components is analyzed according to the detailed coefficients after decomposing. On the basis of the analysis results, the microscopic surface topography of the ultraprecise optical component can be determined whether it meets the requirements of optical applications, which provides reliable reference data for the fabrication of ultra-precision optical surfaces and a basis for further finishing of optical surfaces.

NoC (Network-on-Chip) is widely considered and researched by academic communities as a new inter-core interconnection method that replaces the bus. Nowadays, the complexity of on-chip systems is increasing, requiring better communication performance and scalability. Therefore, the optimization of communication performance has become one of the research hotspots. While the NoC is rapidly developing, it is threatened by hardware Trojans inserted during the design or manufacturing processes. This leads to that the attackers can exploit NoC's vulnerability to attack the on-chip systems. To solve the problem, we design and implement a replay-type hardware Trojan inserted into the NoC, aiming to provide a benchmark test set to promote the defense strategies for NoC hardware security. The experiment proves that the power consumption of the designed Trojan accounts for less than one thousandth of the entire NoC power consumption and area. Besides, simulation experiments reveal that this replaytype hardware Trojan can reduce the network throughput.

With the development of electromechanical servo technology, the electromechanical servo mechanism, with its small size, simple reliability, easy maintenance, good process and easy control, has attracted extensive attention and in-depth research, and has been widely used in the field of aerospace. With the complication of application environment and situation of electromechanical servo system, It is necessary for the servo driver to carry out its own characteristic test before the whole assembly test. The performance test of Servo drive is an important process before the factory. Its performance also directly affects the subsequent system debugging, which makes the development of testing system and method of current output capability of high voltage and large current high-power driver appear very important. At present, for the performance test of Servo drive, it is realized by using v/f mode output fixed amplitude and frequency current, this method can only test the performance of servo drive under specific operating conditions, but not the performance curve of the whole flight process, and it is difficult to judge whether the drive meets the flight requirements. If the actual condition is completely simulated, a large number of test equipment is needed, which can only be targeted at a specific project, and will cause waste of resources. Therefore, it is very important to study the optimal matching of the control parameters of the electromechanical servo system in low voltage system and the test and debugging methods in the process of mastering the design technology of the electromechanical servo system of the Low-voltage high current energy system, the low voltage large current servo-control driving technology and the low voltage dynamic servo motor design Technology Keywords: Aerospace servo-driven flight curve simulation output capability test cost control.
