How to deal with the data after the sensor collects it?

1. In the use of sensors, we often need to organize the sensor data in various ways to achieve better results in the application. The following describes several commonly used simple processing methods:

1. Weighted smoothing: Smooth and equalize sensor data to reduce the impact of accidental data mutations;

2. Extracting mutations: Remove static and slowly changing data backgrounds, emphasizing instantaneous changes;

3. Simple moving average: Keep the K most recent data in the data stream and take the average;

What are the filtering algorithms?

There are many kinds of filtering algorithms. Common ones include: Mean Filtering: The average value of each pixel in the image is calculated, and the value of the pixel is set to the average value of the neighboring pixels. This method can eliminate noise in the image. Median Filtering: The value of the pixel is set to the median value after the sorting of the neighboring pixels. This method can eliminate salt and pepper noise. Gaussian Filtering: Convolving the image using a Gaussian function can smooth the image and reduce noise. Butterworth Filtering: Convolving the image using a Butterworth filter can reduce noise and enhance edges. Exponential Filtering: Convolving the image using an exponential function can enhance edges and reduce noise. Layer filter: The image is convoluted using the layer operator, which can enhance the edges and detect the edge direction. Laplace filter: The image is convoluted using the Laplace operator, which can detect the edges and enhance the edges. Kalman filter: A statistical-based filtering algorithm that can be used to process data with noise, such as sensor data. Intermediate value filter: Setting the value of the pixel to the intermediate value after the sorting of the neighboring pixels can reduce salt and pepper noise. Maximum filter: Setting the value of the pixel to the maximum value after the sorting of the neighboring pixels can enhance the edges and reduce noise. Adaptive filter: Adaptive filtering based on the local characteristics of the image, such as adaptive mean filter and adaptive median filter. These filtering algorithms have their own characteristics, and the appropriate filtering algorithm can be selected according to the specific situation.

Position sensor algorithm?

1. In the use of sensors, we often need to organize the sensor data to achieve better results. The following are simple processing methods that are often used:

1. Weighted smoothing: smoothing and equalizing sensor data to reduce the impact of accidental data mutations;

2. Extracting mutations: removing static and slowly changing data backgrounds, emphasizing instantaneous changes;

3. Simple moving average: keep the K most recent data in the data stream and take the average;

Second, weighted smoothing

The algorithm is as follows:

(new value) = (old value) * (1-a) X * a

where a is the set weight, X is the latest data, the program is implemented as follows:

floatALPHA = 0.1f;
