技术领域 FIELD

[0001] 本发明属于激光测量领域,具体涉及一种自校准的双工位激光水平测高仪。 [0001] The present invention belongs to the field of laser measurement, in particular to a self-calibrating laser level duplex altimeter.

背景技术 Background technique

[0002] 国民经济生产中对于高度的测量需求很多,大到地质勘测、建筑物高度测量或者山脉相对高度测量,可以称为地理测高;小到身高检测、机械零件尺寸检验等,可以称为物体测高。 [0002] Production economy height measurement needs many large geological surveying, building or mountain height measured relative height measurement, may be referred to the geographical high frequencies; detecting small height, dimensional inspection machine parts and the like, may be referred to altimetry object.

[0003] 关于高度的测量方法或者仪器已经有很多,在一些建设项目的工地上,技术人员进行地理测高工作所使用的仪器是经玮仪。 [0003] There are already about a high degree of measurement instrument or a lot, on the site of a number of construction projects, technical personnel altimeter instrument geographical work is used by Wei instrument. 经玮仪由望远镜、水平度盘、竖直度盘、水准器、基座等组成。 Wei instrument via a telescope, horizontal angle, vertical dial, vial, base and other components. 测量时,将经玮仪安置在三脚架上,用垂球或光学对点器将仪器中心对准地面测站点上,用水准器将仪器定平,用望远镜瞄准测量目标,用水平度盘和竖直度盘测定水平角和竖直角。 Measurement, the instrument was Wei the tripod with plumb bob or optical plummet instrument centering the station on the ground, with the instrument set level vial, with the telescope measurement target, with a horizontal circle and a vertical Determination of horizontal and vertical angle plate.

[0004] 进行物体测高主要是高度尺,是放置于平台上进行单轴测量的仪器,理想的情况是花岗石平台。 [0004] mainly performed altimeter object height gauge, is placed on the platform uniaxially measuring instruments, ideally granite platform. 还有一种是基于三角测量原理的激光测距仪,通过对相关倾角以及辅助距离值的测量间接实现对目标高度的测量。 There is also a laser range finder based on the principle of triangulation, to achieve indirect measurement of target height by measuring the inclination and the relevant auxiliary distance value. 申请号为201010256289.5的专利通过测高仪上的角度计测量观察被测物体最高点时的仰角,然后测量被测物体最高点到观测点的水平距离,从而通过三角关系实现高度测量。 Patent Application No. 201010256289.5 measured elevation angle when viewed through the highest point of the object on the altimeter angle, and then measuring the highest point of the object to the horizontal distance of the observation point, resulting in highly measured by a triangle.

[0006] 1、由于测量原理不同、量程不同、测量精度等级不同,现有的测高仪器都是专用设备,不能兼顾地理测高和物体测高。 [0006] 1, due to the different measuring principle, different ranges, different accuracy level measurement, height measurement instruments are conventional equipment, and can not take into account the geographical object altimetry altimetry.

[0007] 2、现有的测高仪器,测量精度依赖于测量基准面的水平度,测量仪器需要摆放在稳定、平整的基准表面上,并且水平度的测量一般依靠自带或外部的气泡水平仪,水平检测精度不高,调节不方便。 [0007] 2, a conventional altimeter instrument, the measurement accuracy depends on the level of the measuring reference plane, measuring instruments need to be placed on a stable, flat reference surface and measuring the levelness generally rely on external or built-in bubble level, the level of the detection accuracy is not high, inconvenient regulation.

[0008] 3、现有的测高仪器,对于凹模、型腔等零件上槽、孔等特征部位的高度,由于探头难以伸入,无法测量。 [0008] 3, a conventional altimeter instrument, wherein the height of the groove portions, the other parts of the die holes, cavities, etc., since it is difficult to project into the probe, can not be measured.

[0009] 4、经玮仪的测量过程需要多人协作,操作复杂;高度尺的测量过程是接触式测量,与操作者的经验关系很大,测量结果的重复性较差。 [0009] 4, the measurement instrument needs collaborative multi Wei, complex operation; measuring height gauge contact measurement process, a great relationship between the operator's experience, the poor reproducibility of the measurement results.
