摘要： The present disclosure provides a method for measuring an angle and a distance. The method includes: at an initial position, after a laser emitting device aligns with a laser receiving device, recording a first angle and measuring a first distance between the laser emitting device and the laser receiving device; and moving the laser receiving device from the initial position to a first position, and after the laser emitting device realigns with the laser receiving device, recording a second angle and measuring a second distance between the laser emitting device and the laser receiving device. The method for measuring the angle and the distance creatively records the corresponding angle and distance at different positions, respectively, such that the position of the laser receiving device relative to the laser emitting device is accurately determined. In addition, the present disclosure also relates to a method for plotting a trajectory map and a laser ranging system using the above method.

摘要： A control system for a rotary laser receives control information transmitted by a communications terminal via a first repeater coupled to the communications terminal and transmits the control information to a controller via a second repeater disposed on a rotary laser. The controller regulates an operating state of the rotary laser based on the control information. The control system enables the communication terminal to wirelessly control and operating state of the rotary laser via cooperation between the first repeater and the second repeater so as to achieve a remote control and to avoid use of a dedicated remote control alone, reduce the system costs and be carried easily.

摘要： 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.
