Description
Technical field
The present invention relates to field of measuring technique, the especially high measurements of total powerstation instrument.
Background technology
Instrument higher position is to set up the ground survey control point of total powerstation to the vertical distance of instrument scale central point.Total powerstation
The high precision of instrument directly determines the precision of coordinate elevation to be measured and trigonometric levelling, the influence for entire measurement accuracy
It is very big.
（1）Steel tape mensuration
Most traditional instrument high measurement method.Instrument height is vertical distance of the measurement control point to instrument scale center, is directly surveyed
Amount is not because being flat relation of plane, and there are errors, and in addition steel tape measurement accuracy is not high.
（2）Suspension surveying method
1. total powerstation is erected at distance measurement object remotely so that the vertical angle of survey station telescope to outstanding high point is less than 45
Degree.Because if vertical angle is larger, the altitude difference error that trigonometric function calculates is larger.2. being projected on ground in outstanding high point
Datum mark erects prism.The line of survey station and ground reference point, the preferably trend with Suspension surveying object intersect vertically.3. entering
The Suspension surveying program of total powerstation inputs prism height, and alignment prism simultaneously presses measurement key, observation survey station and datum mark prism away from
From.4. unclamping the braking of telescope vertical direction, sight the outstanding high point above prism, instrument can with the rotation of vertical circle,
Show corresponding ground point to the height difference for hanging high point.This measurement method operation sequence is cumbersome, and error includes mainly Laser Measuring
The error that prism away from error, trigonometric function error and introduction is brought.
（3）Laser optical method
Currently, there is a kind of index plane laser ranging total powerstation instrument height measuring system, laser displacement sensor is vertically mounted to
Under total powerstation pedestal, it is high can easily and efficiently to read total powerstation instrument for the measurement mark being aligned on ground.Its existing weight
It is to have ignored to measure the millimetre-sized error that the groove at the upper centering mark of mark is brought to laser ranging to want problem.This be by
In, 1, laser alignment when, laser center is injected into groove, and the distance of measurement may be deep into inside grooves, be not to
Measure the distance of mark top end surface；2, inside grooves and its surrounding are rough, cause laser reflection light direction chaotic,
The intensity of reflected light and poor quality received is terminated by laser pick-off, and very big error is brought to laser ranging.
The measurement accuracy of the above measurement method is grade, the not applicable occasion for needing fine instrument high parameter.In order to
Meet certain elevation high-acruracy survey occasions, needs high-precision, easy-to-use total powerstation instrument height measuring system and method.
