Simultaneous Localization and Mapping (SLAM) is the core technology of intelligent robot system, it also basis for its autonomous movement. In recent years, has been found that SLAM using a single sensor certain limitations, such as Inertial Measurement Unit (IMU) noise serious drift, 2D radar can only detect environmental information on same horizontal plane. this regard, paper constructs multi-sensor back-end fusion algorithm combines vision, laser, encoder IMU information. Experiments...
The size of the field uncertainty (FOU) is an important performance indicator spatial optical communication systems and closely related to line-of-sight (LOS) pointing accuracy. Considering aircraft-ground laser as research background, initial angle LOS obtained using coordinate transformation matrix, factors that affect accuracy error are analyzed. Kalman filtering technique introduced into system complete modeling simulation analysis. results show position, attitude angle, other data...
To investigate the toxicokinetic differences of 3,4-methylenedioxy-
With the aging population in our society, there is a growing demand for detection of vital signs. Millimeter-wave radar has gained significant attention due to its high accuracy and non-contact nature. To enhance heart rate prediction, this paper proposes method based on hybrid CNN-Transformer model. In method, CNN layer utilized extract local features heartbeat phase, compensating limited information mining capability Transformer encoder when dealing with multivariate datasets....
As artificial intelligence flourishes and many related technologies continue to develop, Visual Simultaneous Localization Mapping, as the "vision" of robots, can utilize a large amount environmental information. In addition, semantic segmentation distinguish background in image from moving objects. recent years, convolutional neural networks have been successfully applied processing, subsequently entered field V-SLAM research. Related researchers tried directly use extract features for loop...
LMS (Least Mean Square) algorithm has become a very commonly used in the field of adaptive filtering due to its many advantages such as easy calculation, application and strong robustness. The main idea is automatically adjust parameter values filter minimize Square Error (MSE). traditional fixed-step problem that error accuracy convergence speed cannot be coordinated, so improved variable-step algorithms have emerged. This article introduces several new through examples.

This paper introduces the automatic measurement system of laser scattering method based on angular resolution. Discuss principle in optical element surface scattering, propose which use angle resolved (ARS) to measure roughness, at same time experimental platform is built results after verifying correctness method.
PID controller is widely used in industrial process control, however, because of improper parameter, most the controllers have failed to meet control requirements. This paper proposes parameter tuning method based on vector model complex plane, not only can solve parameters easily and quickly according controlled plant, but also simplify tuning. It has advantages smaller amount calculation stronger versatility. Simulation results show that simple effective, designed by using this a good gain...
A design method of enhanced robust fractional order PID controller is proposed to control electrical machinery system. Magnitude margin constraint, phase constraint and the gain robustness constraints partly flat in specified dots around crossover frequency are adopted which has stronger open-loop variation compared with integer controller. Besides, nonlinear optimization function hunt for optimal parameter solutions controller, so five parameters can be solved. The system models simulated...
Abstract In view of the fact that traffic sign detection is becoming more and important in assisted driving, but there are situations where target small, occluded background complex, this paper proposes a Transformer-based improved Faster R-CNN algorithm for detection. The uses Transformer network based on shift window as backbone. multi-level feature map fused across layers through cascade fusion module to obtain map. Moreover, model’s extraction ability improved. head eliminates rounding...
Abstract Small targets are discovered despite the challenges posed by limited number of features, low resolution, difficulty in extracting discriminative characteristics, and ease interference from external influences. A modest target detection technique based on enhanced YOLOv5s is suggested this research. First, a test storey dedicated to tiny objects appended characteristic fusion part algorithm help model efficiently acquire features with smaller sensory fields; second, find more...
