What is the principle of Laser Distance Measure?

Laser Distance Measure is an instrument that uses a specific parameter of the modulated laser to measure the distance to the target. According to the distance method, it is divided into phase method rangefinder and pulse method rangefinder. The pulsed laser rangefinder shoots a beam or series of short-lived pulsed laser beams at the target during operation, and the photoelectric element receives the laser reflected from the target. The timer measures the time from emission to receipt of the laser beam and calculates the distance from the observer to the target.

What is the principle of laser rangefinder?

A laser rangefinder is an instrument that uses a specific parameter of the modulated laser to accurately measure the distance to the target. The pulsed laser rangefinder shoots a beam or series of short-lived pulsed laser beams at the target during operation, and the photoelectric element receives the laser beam reflected from the target. Distance from instrument to target.

If the power of the emitted laser beam is sufficient, the measuring range can reach about 40 km or even further, and the laser rangefinder can work day and night, but if there are substances with high laser absorption rate in the room, the distance and accuracy of the rangefinder decrease.

Install the laser rangefinder under the cabin of the gripper ship unloader, and the laser scans vertically down. After the system is ready, a start command is issued by the controller. The laser emits short laser pulses at high speed and measures the area below it point by point with extremely low angular resolution. After a large number of measurement data points have been collected by the software, they are converted into point cloud data in three-dimensional space, and then the data collected by the laser is converted into position and contour information of the material through a special data processing algorithm. The information is output to the higher-level control system. After the control system has determined the next gripping point, the execution system completes gripping.

How do I use the laser rangefinder?

1. Touch the Start/Measure button of Laser Distance Measure to turn on the rangefinder.

   
   

2. Press the plus or minus button to change the measurement reference edge as needed (applies to a single measurement only), A – front edge; B – instrument carriers; C – trailing edge.

   
   

3. Aim the laser at the target, touch the Start/Measure button again and note the measured value.

   
   

4. When the measurement is complete, press Delete until the start screen appears. Press the plus and minus buttons simultaneously to turn off the rangefinder.

   
   

5. The laser rangefinder shuts down automatically when there is no work order for 90 seconds.

   
   

6. The rangefinder itself can be calibrated based on the standard distance and corrected via the menu item "Offset".
