At present, the methods for measuring the microtopography are mainly non-contact and non-contact. The non-contact type near-field photogrammetry and laser scanning are most widely applied, have the advantages of no damage to the earth surface, higher precision, shorter time consumption and the like, but are difficult to be applied under the condition that the earth surface is covered by vegetation. The needle plate method is used as a main contact measurement technology, can better reflect the fluctuation condition of the micro-topography of the ground surface under vegetation coverage, and is widely used in field investigation. However, the method needs to manually read the scales of the measuring needle in the measuring process, and the working efficiency is greatly limited.
