Description
Technical field
The utility model relates to a kind of surveying instrument, is specifically related to the portable surveying instrument of a kind of trees height and relative coordinate thereof.
Background technology
Trees height and the mensuration of coordinate thereof are the Focal point and difficult points in production of forestry and forest inventory investigation, most important in biomass estimation research.Wherein the height of tree is the important evidence of evaluation site quality and arboreal growth situation and the layering of division forest.Its relative coordinate is also indispensable part in Ecological Investigation, and it is the necessary basic data of spatial ecology.
Present stage, mainly contain both at home and abroad to the measuring method of the height of tree: the assize of mechanical type instrument is high, transit, total powerstation assize is high, the assize of laser type instrument is high and the assize of camera work method is high.The assize of mechanical type instrument is high belongs to traditional method, and the advantage of this quasi-instrument is cheap, easy to use, but its precision is lower, inefficient operation, function singleness, and comparatively bothers the data processing gathered.In electronization, informationalized today, such surveying instrument embodies the falling behind property of Traditional Forestry information acquisition means, hysteresis quality and extensive property.
Although these instrument assizes of electronic theodolite, total powerstation are high saves the time, reduce labour intensity, improve effect and precision, achieve the automatic collection of data, transmission and measuring and calculating, but this quasi-instrument also exists and carries difficulty, complex operation, use complexity, higher to the knowledge requirement of specialty, and forest road is rugged and rough, to total powerstation put and leveling also brings some problems.Therefore, in forest survey work, the altimeter device that can be convenient for carrying and operate more and more highlights its importance.
Now widely used portable altimeter device can be divided into following several according to the difference of principle: mechanical type, ultrasonic type and laser type.The common feature of these three kinds of altimeter devices is exactly the height that can only accurately measure level land or the very little ground object of the gradient, because this kind of altimeter device generally adopts trigonometry assize high, and the method is in measuring process, often first to measure the horizontal range between observer and trees, and most of forest surveying operation all rugged hill path or domatic on carry out, level distance is being scaled after recording oblique distance, height of tree value is calculated again according to formula, its conversion intricate operation and precision is not high, therefore the height of tree value measuring gained is not too accurate.
And this kind of altimeter device generally can only realize, to the measurement of current trees height, can not measuring the relative coordinate of its relative reference point.But in Forestry Investigation work, for the needs safeguarded trees, supvr often will know the positional information of trees, therefore these altimeter devices do not meet the needs of Forest in Current investigation work.
As known from the above, in existing portable altimeter device, also do not exist can to trees height accurately measuring, the altimeter device of the relative coordinate of trees can be measured again, if such instrument can be provided, very large practical value will be had in work on forestry.
