In this paper, we first intruded the scale invariant feature transform(SIFT) and Random Sample Consensus (RANSAC) algorithms, and then we applied the SIFT algorithm based on RANSAC to wide area target tracking by multi-camera, and the experiment proved that the algorithm perform very well in this situation. It gives more intuitive results, which is better than signal view. So it is very beneficial...
Although the coupled dictionary pair is jointly trained for image super-resolution, the sparse representations corresponding to the low resolution patches and high resolution patches are inconsistent. Therefore, we propose a sparse embedding method to establish the mapping relationship of the sparse representation. The manifold spaces of the sparse representations between the low resolution patches...
Run-to-Run control methods as applied in semiconductor manufacturing can greatly benefit from partitioning the observed disturbance state into separate components of tool and product disturbance states. Obtaining sufficiently accurate initial estimates of tool and product disturbance terms from historical data greatly improves the effectiveness of this method. Such an estimation method is developed...
With the development of computational criminology and more powerful computers, mathematical modelling of systems representing some aspect of social crime and the analysis of the resulting numerical solutions is becoming more popular. The problems of social crime and criminal behaviour control are studied according to the system self-organization theory, and from the non-equilibrium crime system point...
Fluorescent magnetic particle inspection is widely applied in industry production, however; traditional ways are manual and depend on individuals' experience, which can also cause damage to workers' eyes. An automatic fluorescent magnetic particle inspection device is presented in this paper. A series of image processing methods have been investigated, which are put into a combination for detecting...
Noise cancellation is the basic step of road surface image processing, such as road roughness detection, road crack detecting. The 2-D data will always be corrupted by noise in the process of road image sampling and digitalizing. Conventional filtering techniques such as median filter and mean filter are designed to dispel single type of noise. While the image data are always contaminated by mixed...
For smooth operation of SCARA robot for wafer transition, a new method using magenetorhelogical damper for vibration suppression is proposed. Vibration often occurs when the acceleration decrease or increase abruptly. Especially in the end of an operation period, the residual vibration decreases the safety of wafer operation and extends settling time. Firstly, Vibration sources are analyzed. And dynamics...
This paper presents two recursive identification algorithms for bilinear-parameter models: a decomposition based stochastic gradient algorithm and a decomposition based recursive least squares algorithm. The key is to decompose a bilinear-parameter model into two fictitious subsystems, and to identify the parameters of each subsystem by replacing the unknown variables in the information vectors with...
Industrial Ethernet is the movement of industrial control network systems. In order to have an overall understanding of industrial Ethernet for the readers, the paper introduces the development of industrial Ethernet. Then further state the mainstream technology of industrial Ethernet in detail. And finally, discuss the development trend of industrial Ethernet and summarize all the paper.
For the rehabilitation of hypertension patients, a feet massage robot was designed. The mechanism structure and its massage process of feet massage robot were determined conforming to the prescription provided by the massage expert. It is one of critical factors for the robot to find and localize the acupoint precisely in order to cure the diseases. By the direct representation, the model of human...
The robotized endoscope holder in laparoscopic surgery allows a surgeon to control the endoscope without the intervention of an assistant. For providing the more convenient interactions between the surgeon and a robotized endoscope holder, we propose a new method for the automatic 3D-tracking of laparoscopic instruments in real-time. The method is based on the measurement of the 3D positions of the...
In measure & control related education and training, the specifications such as cost, flexibility, user experience, and the actual operability are impossible combinations for traditional solutions and products of general object (including control object, sensor and actuator, etc.). In order to resolve this problem, a general object terminal was designed, which combined real electrical signal with...
To test and optimize brushless dc motor (BLDCM) controller, a hardware-in-the-loop (HIL) real time simulation schematic based on DSP plus FPGA was presented. BLDCM model calculating cycle is up to 14us, which leads to the motor states updating at least one motor model cycle time delay, and the delay will result to accumulative error. To pursue an accurate and fast BLDCM HIL simulation results, a new...
Bayesian network is an effective tool for fault prognosis. Learning the Bayesian network structure from data is, however, a difficult problem for complex industrial chemical processes. This paper presents an idea of jointly using Pseudo Bond Graph model and Bayesian network for fault prognosis. Pseudo Bond Graph is used to determine the Bayesian network structure, and the network parameters are learned...
The accuracy of the three dimensional localization of the vision systems of harvesting robots is likely to be effected by the occlusion of leaves and branches. To quantitatively analyze the influence to the localization for tomatoes based on binocular stereo vision caused by the occlusion, we analyzed the three dimensional localization errors of occluded tomatoes in three kinds of occlusion degree...
The decomposition process for the extraction of harmonics components from compressed power quality data was required under the frame of Shannon sample theory, but it increased the complexity of data procedure. A compressed sampling matching pursuit (CoSaMP) method was presented to detect harmonics from compressive sensing (CS)-based compressed power data sequence avoiding decompression pretreatment...
Spatial recognition is one of neural functions of rat's hippocampus. Head direction cells, grid cells and place cells play a major role in this function. Information about direction, distance, and location is integrated in the grid cells. Place cells receive information from grid cell firing and construct representation of the spatial environment of the brain. This representation is demonstrated to...
Focusing on the users is more interested in the sequential patterns that accord with the well completion business process habit overall in the web access mode of well completion mobile platform. This paper proposed a weighted sequential pattern mining algorithm based on the well completion business process. With analyzing the business process models and web access log of well completion, confirm the...
