Abstract: Mesoscale convective system (MCS) has a great influence on the air flight, this article used infrared cloud image data detected by FY2D static satellite, through TBB and area threshold found the MCS from cloud image, then calculated and analyzed the adjacent period of MCS’ cloud area ,centroid position, the development strength and some other characteristic changes to test whether it meet the targets matching principle, finally, discriminated whether the signed cloud were the same target cloud so as to realize the automatic tracking of MCS.

Abstract: Mobile carrier satellite communications are becoming increasingly attention. Civil, with satellite television, satellite Internet access, as well as development of civilian systems such as video phones, on growing demand for mobile communications carrier; the military, rapid response to equipment and mobility as well as steady aim, track and combat capabilities of mobile high demand, also depend on the mobile carrier satellite communications. Mobile carrier satellite communications system is the key equipment of satellite antenna auto-tracking system. Develop performance-price ratio reasonable automatic satellite antenna tracking system to fill the gaps in this area, is of great significance.

Abstract: With the improvement of living standards, people's requirements on their living environment are higher, Especially, safety has become the primary considerationBut now the surveillance cameras which often be installed in residential quarters can only monitor the area setted, can not take initiative to track the target, so the monitoring effect is often not be satisfied. In order to change the fact, writer designed a new monitoring system.In this system, piezoelectric infrared sensors sense humans body, MCU detects sensors output signal, then controls motor to make the camera can automatic tack human body in residential quarters.

Abstract: In this paper, the design is with the single chip microcomputer as the core of automatic tracking controller. The system is mainly composed of the signal acquisition part, the signal conditioning part, a control circuit and a drive circuit. The signal collection circuit composed of photosensitive resistance sensors to collect light signal, signal conversion circuit with voltage follower LM324 convert the change of light intensity to the change of the voltage, through the voltage comparator LM393 produce high and low level control stepping motor rotation; Control circuit use the AT89S52 as the main control device, output different control signals to the driving circuit; Driving circuit use the ULN2003 as driver stepper motor. Is obtained by simulation debugging, physical test, the error rate is less than 5%, in order to realize the efficient utilization of solar energy.

Abstract: In order to solve the problem that high-rise users can't install traditional solar water heater for limited area and the problem that the utilization rate of panel position fixed solar energy is low, this paper proposed a new design of high-rise building integration solar water heater, which can make solar water heater integrate with high-rise building, and has the function of tracking sunlight automatically in real time, raising the utilization ratio of solar energy, and prolonging sunshine time. In addition, the auxiliary electrical heating system can be intelligently started or closed by setting the temperature sensor in the storage water tank of water heater. Humidity sensors automatically control the stretch of panel according to humidity, which can effectively protect the panel and prolong its life, and preferably realized green and energy-saving architectural concept.

Abstract: Based on introducing the traditional scan and single target tracking state, focuses on the automatic tracking characteristics of each stage under the condition of multiple targets. The two form of automatic tracking multiple targets, and the development direction of the future.

Abstract: This article according to the characteristics of the normal vector plane method is proposed to motion principle, sunlight vertical cliff movement equation, designed a solar energy automatic tracking model, principle of the system to conduct a comprehensive analysis, gives the related transformation equation, the system motion control equation is established.

Abstract: Aiming at the low generating efficiency of the current solar energy generating system, solar energy maximum power point tracking control system based on STC89C52 is designed and made. The photoelectric detection and tracking is adopted as the control mode in the system. By using stepping motor as driving mechanism, comprehensive trace of the sun is realized by controlling the movement of tracking mechanism in the horizontal and pitching directions. Based on this, real-time detection of wind velocity and change of wind direction is realized by wind velocity and direction transducer which is equipped on the tracking mechanism, which makes the system automatically avoid the typhoon above level 8 to weaken the damage to panel by the storm. The experiment results of model machine indicate that the system has reliable performance which can satisfy the need of auto-solar track, it can also make the panel orient towards east again after darkness to realize daily circular run and it is of relatively high practical value.

Abstract: We proposed an online method of tracking the tunnel cable based on egomotion estimation. The method is firstly applied key point detection algorithm to extract feature points, and then the points are matched to estimate the matrix of egomotion representing the camera movement. Finally, we use the matrix to locate a mask around the cable in each frames captured inside the power line tunnel. The experimental results show robustness and efficiency of our method.

Abstract: This paper proposed a design of algorithm of an excimer laser coaxial observation processing system which can automatically track preset line. With using of the Visual C + + image processing technology and the least square method, the XY axis in both directions of processing platform can obtain accurate processing displacement, and stability control platform for real-time tracking a straight line center. Processing system can acquire the coordinate of processing place where can get the distance from the centre of image in order to achieve real-time tracking.
