Embodiment Construction

[0019] According to the present invention, the cabin section to be docked is a cylinder, and it can be known from mathematical knowledge that if the three-dimensional coordinates of 4 or more non-collinear points on the cylinder surface are obtained, the axis equation of the cylinder can be obtained through the cylinder equation. The attitude difference of the two cabins and the difference of two position coordinates perpendicular to the axial direction of the cylindrical cabin body can be obtained by the axis equation of the docking cabin body. The processing accuracy of the surface of the cabin body generally does not meet the docking requirements, and more accurate position information of the docking positioning device needs to be drawn out to 4 or more non-collinear visual marker points on the outer surface of the cabin body through fixtures. The same, so the visual marker points are attached at the same position on each cabin body.

[0020] The present invention needs to ...

Abstract

The invention relates to a single-camera laser-assisted cabin docking device. The single-camera laser-assisted cabin docking device comprises a central processing unit, a base (1), a single camera, a two-degree-of-freedom rotary table, a laser range finder and two electric motors. A camera stand (2) for supporting the single camera is fixed on the base (1) and extends out of a mounting plane by a certain distance so as to obtain required vision. The two-degree-of-freedom rotary table comprises a spindle (3) and an objective table (7) mounted on the spindle (3). The laser range finder (8) is fixed on the objective table (7) of the two-degree-of-freedom rotary table, and the spindle (3) of the two-degree-of-freedom rotary table has a specific length to guarantee that the laser range finder fixed on the objective table (7) is similar to the single camera in laser point reach range. The invention further provides an assisted docking method implemented by the single-camera laser-assisted cabin docking device. The single-camera laser-assisted cabin docking device and the assisted docking method have the advantage that two cabins to be docked can be measured simultaneously.

Description

Technical field [0001] The invention relates to a device for docking by using three-dimensional measurement to assist cabin sections, in particular to realize three-dimensional coordinate and attitude measurement of two docking cabin sections by using a laser rangefinder to assist a monocular camera. Background technique [0002] Three-dimensional measurement technology is a technology that directly measures or indirectly estimates the three-dimensional information of an object. Compared with the traditional two-dimensional image information, the three-dimensional information of the object can reflect the objective object more comprehensively and truly, and provide people with more information. Three-dimensional measurement mainly includes two categories: contact and non-contact. Docking technology refers to the technology in which different components are combined into a unified whole. The docking device includes a position and attitude deviation detection device between ...
