The invention discloses a wall surface monitoring method based on a marking instrument. According to the technical scheme, the wall surface monitoring method comprises the steps of controlling the marking instrument to be parallel to a straight line with the distance Z from a wall surface; enabling the marking instrument to be parallel to the wall surface and move in one way according to a planning step length and program; controlling an unmanned aerial vehicle to translate along with the marking instrument, and continuously and repeatedly changing flight height after every round trip translation; every time after the height is changed, measuring the distance from the unmanned aerial vehicle to the wall surface by a laser range finder on one side of the unmanned aerial vehicle; meanwhile measuring the flight height and obtaining a horizontal position after translation from the marking instrument by the unmanned aerial vehicle; storing the above data set by the unmanned aerial vehicle;and transforming the data set into a three-dimensional vector diagram for showing the straightness of the wall surface by an upper computer. The wall surface monitoring method based on the marking instrument has the advantages of wide application range, high accuracy and convenience in use.
Description
technical field [0001] The invention belongs to building detection, and in particular relates to a wall surface monitoring method and system based on a marking instrument. Background technique [0002] The flatness or straightness of the verticality of the building wall is an important indicator in the construction field. The vertical flatness or straightness of the wall as a whole has a very important influence on the aesthetics and quality of the wall. Existing detection of the vertical flatness or straightness of the wall of a building generally uses theodolite or total station. It is possible to carry out sampling inspection on the wall surface, but it cannot reflect the vertical flatness or straightness and data of the entire wall surface. [0003] Measurement steps of building verticality deviation: select the building to be tested, and must meet good visibility conditions, and the top of the building can be seen at points in two directions that are more than 1.5H awa...
