Embodiment Construction

[0060] Such as image 3 A two-degree-of-freedom laser scanning method shown comprises the following steps:

[0061] Step 1. Scanning target point setting: select N ground points as target points in the pre-set scanning area of ​​the laser 1, where N≥3; the laser 1 is installed on a two-degree-of-freedom pan / tilt.

[0062] In this embodiment, N=4, the preset scanning area of ​​the laser 1 is a rectangular scanning area, and the four target points are respectively four vertices of the rectangular scanning area.

[0063] In this embodiment, the four target points are P 1 ,P 2 ,P 3 and P 4 , where P 1 is the lower left vertex of the rectangular scanning area, P 2 is the lower right vertex of the rectangular scanning area, P3 is the upper left vertex of the rectangular scanning area, P 4 is the upper right vertex of the rectangular scan area.

[0064] In actual use, P 1 ,P 2 ,P 3 and P 4 It can also be the lower right vertex, the lower left vertex, the upper right verte...

Abstract

The invention discloses a two-degree-of-freedom laser scanning method and a hollow numerical control holder. The scanning method includes the following steps of 1 scanning target points setting which includes selecting N ground points in a preset scanning area as target points, 2 target points three-dimensional coordinates determining which includes determining three-dimensional coordinates of the selected N target points respectively and 3 automatic scanning which includes that the hollow numerical control holder comprises a two-degree-of-freedom holder body which comprises a cabinet body and a hollow horizontal rotating platform installed on the cabinet body, a laser is installed in the cabinet body, and a light reflection mirror used for reflecting laser light beams transmitted by the laser and driven by a pitching adjusting mechanism to rotate vertically in the vertical face is installed on the horizontal rotating platform. The method and the holder are reasonable in design, convenient to operate and achieve, good in use effect and capable of solving the problem that complex and accurate coordinate demarcation is required on site in use of the existing two-degree-of-freedom holder, a laser facula position calculation result is low in accuracy and the like.

Description

technical field [0001] The invention belongs to the technical field of two-degree-of-freedom scanning, and in particular relates to a two-degree-of-freedom laser scanning method and a hollow numerical control platform. Background technique [0002] Flying birds on the airport pose a great hidden danger to flight safety. Birds being sucked into the aircraft engine may cause the tragedy of aircraft crash and death. Bird repelling is a very heavy task in every airport, and unattended laser bird repelling equipment came into being. The effect of laser bird repelling is good, but there is a key problem that must be well solved, which is the accurate calculation of the spot position in the polar coordinate system. [0003] The principle of laser bird repelling is to control the left and right rotation angle u of the horizontal axis of the two-degree-of-freedom platform and the pitch angle v of the pitch axis through a two-degree-of-freedom platform with a height of more than one ...
