The invention discloses a
wind power blade size measuring device based on
machine vision, and belongs to the technical field of
laser measurement, the
wind power blade size measuring device comprises a supporting seat and an annular rod, the supporting seat is provided with two moving holes, the annular rod is located in the moving holes, and a sliding supporting mechanism is slidably arranged outside the annular rod; according to the device, key components such as an annular rod, a second driving
assembly, gears, a toothed bar, a
laser measuring
assembly, a first driving
assembly and a reciprocating screw rod are adopted, the annular rod and the toothed bar with gaps can keep smooth and stable rotation through the arrangement of four supporting wheels and two gears, the stability of the device is improved through the design, and the accuracy of the device is improved. In addition, the rotating
laser measurement assembly can carry out laser measurement on the
wind power blade along multiple angles, the multi-angle measurement mode enables laser measurement not to be affected by light and
fixed angle measurement easily, and therefore the accuracy of the laser measurement result is guaranteed to a certain degree.
