  "textContent": "The present disclosure relates to a ranging method and a ranging system, the ranging method includes using a first laser emitting portion of a laser emitting device to emit a vertical laser beam rotating in a vertical plane at a first rotation speed; calculating a time difference between the vertical laser beam passing through a first optical detection component and a second optical detection component by using the first optical detection component and the second optical detection component on a laser receiving device at least partially on the same vertical plane, wherein a distance between the two optical detection components is a first spacing; and calculating a first distance between the laser emitting device and the laser receiving device based on the first rotation speed, the first spacing, and the time difference. The method of the present disclosure can ensure that the first and second optical detection components provided on the laser receiving device can be set horizontally, thereby ensuring that the distance between the specific positions on the first and second optical detection components that the vertical laser beam passes is exactly the first spacing, thereby ensuring that the measured or calculated first distance is accurate.",
