The measurement method of novel rectangular hull area measurement instrument, steps are as follows:
Step 1: hand-held reading pole pedestal adjusts the angle α at shaft, makes elastic material A, elastic material B, elastic material
C, the length-width ratio of the surrounded rectangular field of view profile of elastic material D is approximate with object to be measured length-width ratio.
Step 2: reading pole being held level with both hands, flushes survey person's pupil with peep hole pedestal top edge, adjustment peep hole pedestal
The angle α is finely tuned in position, observes object to be measured by peep hole, makes object to be measured outer edge and elastic material A, elastic material B, bullet
Property material C, the surrounded rectangular field of view profile of elastic material D are completely coincident；
Step 3: the distance of the top edge of peep hole pedestal to reading pole bottom is d meters, and object to be measured distance is D meters, is surveyed
Out corresponding s square metres of surrounded rectangular area of elastic material under the angle α, s by rigid pole A, rigid pole B length and between angle α
It is calculated, then the target area at D isSquare metre.
The measuring instrument need of work knows target range (in the sea), can use pathfinder, range estimation, reckoning, watercraft AIS system
Equal different modes obtain.
Beneficial effects of the present invention:
1. quickly, the ranging scope of application is big for measurement.When target range is 1 nautical mile or when close to 1 nautical mile, target area can be by
Reading pole is directly read；When distance is k nautical miles, target area k2Read pole reading.
2. cheap, maintenance is simple and easy, good reliability.Equipment does not have electronic chip, at low cost, does not need electricity
It tries hard to keep barrier, is not afraid of into water, it is not easy to it damages, it is simple and easy to do maintenance after damage.
3. " sea " taste is dense, equipment is using to connecting.The shipborne equipments such as radar are for marine distance mostly in form in the sea
It provides, can be used directly when carrying out area measurement using the equipment, it is not necessary to convert.
4. as long as the environmental suitability of equipment greatly improved can find that objective contour can measure.
