Working Principle Introduction

By combining various ranging model algorithms, the distance of the object is obtained, and the actual distance is displayed through the serial port and the screen.

*   ‌**Perspective Projection Model**‌: Based on the pinhole camera model, the distance is calculated using the relationship between the projected size of the object in the image and its actual size. The formula is X/Z = x/f, where (X,Y,Z) is the position of the object in the camera coordinate system, (x,y) is the image coordinate, and f is the focal length.
*   ‌**Size-Ratio-Based Ranging**‌: The distance is calculated using the known actual size of the object and its projected size in the image. For example, given the object width W and the pixel width P, the distance can be calculated by the formula D = W×f/P.
*   ‌**Geometric-Relationship-Based Ranging**‌: The distance is calculated using the geometric features in the scene (such as the horizon and pitch angle), which is suitable for fixed-installation cameras.
*   ‌**Deep-Learning-Based Ranging**‌: The depth information is regressed directly from the image through a neural network, without the need for an accurate camera model, but it requires a large amount of labeled data.
