What factors will affect the accuracy of laser rangefinder?

1, weather and environmental factors. The principle of laser rangefinder measurement is to measure the distance by using the linear propagation and reflection of light. Due to the change of atmospheric state, the vertical distribution of atmospheric refractive index is uneven in space, and refraction will occur in the measurement process, resulting in measurement errors.

2. Temperature factor. Generally, if the temperature is higher than 50 or lower than 40, the laser will not work.

3. Distance factor. When the measuring range is far away, there is the influence of the curvature of the earth.

4. Human factors. Whether the operation method of rangefinder users is standardized also affects the ranging accuracy.
