Embodiment 1
[0042] see figure 1 , this embodiment provides an accuracy measurement device for laser radar.
[0043] The accuracy measuring device includes a horizontal linear track 11 , a displacement platform 12 for moving on the horizontal linear track, several laser range finders 13 , a laser target 14 and a laser pointer 15 .
[0044] The laser radar 16 is fixed above the displacement platform.
[0045] The laser target is arranged at one end of the horizontal linear track, and the laser radar is aimed at the laser target.
[0046] The laser pointer is fixed on the laser radar and aligned with the laser target. When the displacement platform moves on a horizontal linear track, the marking position of the laser pointer on the laser target remains unchanged;
[0047] The laser range finder is used to measure the distance between the displacement platform and one end of the horizontal linear track;
[0048] The laser radar is used to obtain the length of the laser target;
[0049] Th...
