| description | The invention is suitable for the technical field of radars, and provides a distance measurement method and device, terminal equipment and a computer readable storage medium, and the method comprises the steps: extracting the signal features of an original echo signal; determining a target ranging timing value according to the signal characteristics; and calculating the distance of the target object according to the target distance measurement timing value, extracting signal features capable of representing the self-correlation degree of the signal intensity in each signal segment, carrying out threshold detection by using the signal features, and further calculating the target distance measurement timing value for calculating the distance of the target object. According to the invention, the detection distance of the laser radar in a low signal-to-noise ratio scene can be increased, and the ranging performance of the laser radar in a long-distance detection scene can be improved.
