The invention discloses a quick and stable cell nucleus location method in order to solve the problem that the processing speed of the traditional cell nucleus location algorithm can hardly meet the requirement of large-scale digital pathological full-slice computer-aided analysis. First, a color de-convolution algorithm is used to extract the cell nucleus component in a pathological image; then, the center position of the cell nucleus is highlighted by a mixed Gaussian filter; and finally, the local maximum value is found in the filtered cell nucleus image, and the position of the cell nucleus is determined through adaptive threshold judgment. The method has the advantages of clear process, easy implementation, low time complexity, fast execution and stable location effect, and is of great significance in digital pathological full-slice computer-aided analysis.

The application discloses a method for expanding the capacity of a cluster system and a base station. The method includes judging whether the number of current terminals exceeds the preset number of bearers, wherein the current terminal is the sum of communication terminals that have subscribed to GPS and communication terminals that apply for subscription to GPS; if the number of current terminals exceeds the preset number of bearers, then Adjust the initial GPS subscription period of the subscribed communication terminal, so that the adjusted number of bearers is greater than or equal to the number of current terminals; wherein, the preset number of bearers is the number of bearers corresponding to the initial GPS subscription period. Through the above method, the present application can automatically adjust the GPS subscription cycle, thereby realizing the expansion of the trunking system and meeting the needs of more terminals for GPS positioning.

The invention discloses a real-time continuous positioning method in a UWB-based NLOS tunnel environment, including: each label node communicates continuously with all adjacent anchor points, measures the distance from itself to the anchor point, and uses the least square method to predict the label Then use a greedy clustering algorithm to estimate the position of the label node, and finally determine the final position of the label node according to the predicted position and estimated position. The method of the invention makes positioning more accurate and meets the needs of tunnel personnel and vehicle positioning.

The invention relates to an image processing method for positioning eyes. The invention adopts a technical proposal that the method comprises the following steps of: acquiring an image of a face; and detecting the image of the face, establishing probability support vector machine appearance models for three components including eyes and nose respectively, establishing the Gaussian distribution models of the measuring parameters of the spatial structure of the three components respectively, redefining the length of three edges and establishing Gaussian distribution models, establishing an enhanced image model, selecting candidate points of maximum appearance characteristic similarity and maximum structural similarity as the optimal positions of a target, and determining the possibility of human eyes z1 and z2 or nose z3 according to an appearance characteristic ui shown by the probability support vector machine appearance models on the basis of the probability support vector machine appearance models to position the eyes. The method overcomes the drawbacks in the prior art such as high requirements on image resolution ratio, light and definition, and difficulty in the positioning of the human eyes in a complex environment accurately. The method establishes a high robustness space structural model starting from the appearance characteristics of eyes and the characteristics of the spatial distribution structure of the eyes and the nose and improves human eye positioning accuracy.

The invention provides a multi-sensor data fusion robot positioning method. The environment recognition sensor transmits the collected external environment information to the industrial computer and draws the environment map, and judges the pose of the robot itself and whether it moves to The area of ​​the target can be well positioned by the robot through the use of sensor data. The present invention conveys richer environmental information to the robot through the combined use of binocular cameras, laser radar and differential GPS, solves the problems of less environmental information of two-dimensional lasers and high cost of three-dimensional lasers, and also provides more accurate outdoor positioning information.

The invention provides a security and protection robot. A front wheel steering and back wheel driving structure manner is adopted, a multi-sensor data fusion positioning method is used for motion, a vehicle frame, a front wheel assembly, a back wheel assembly and a steering mechanism are included, the front wheel assembly and the back wheel assembly are supported to the front end and the back endof the vehicle frame correspondingly, and the steering mechanism is installed on the lower surface of the vehicle frame.
