Technical field
The present invention relates to animal tracking technical field, more specifically to a kind of method for tracking Cetacean.
Background technology
Theodolite is the main angle measuring instrument in mapping operations, by telescope, horizontal limb, altitude circle, spirit level, base
The composition such as seat, can measure horizontal angle and vertical angle.Theodolite is successfully applied to various cetaceans since 1970s
Zooscopy.The method for tracking Cetacean with theodolite can be accurately positioned the position that animal occurs on map, so as to enter
The related research of row, it is main include the behavior in its natural state of research animal, the motor pattern for studying animal, research ship with
Contact, the Habit at selection of research animal between animal etc..Under field conditions (factors), it is tracked when Cetacean can not be captured
Mark or when being identified by taking pictures, can yet be regarded as a kind of effective method using theodolite track and localization.This method is not only
The behavior of animal is not upset, and can be accurately positioned and track Cetacean in the range of large scale, while field can also be saved
The input of investigation.
In the prior art, when tracking Cetacean using theodolite, as shown in figure 1, theodolite generally is positioned over into one
Higher favourable observation position, calculates the height h of theodolite position, obtains dynamic with target cetacean using transit survey
Included angle A between thing, by solving a triangle ABC can calculate between theodolite and animal apart from b, according to theodolite position
Coordinate information be the coordinate information that can obtain target Cetacean so that reach tracking Cetacean purpose.But this side
Method needs one at least 20 meters of observation platform（That is h >=20m）, otherwise make the angle between target Cetacean too big, cause
The data of acquisition are insincere.
Therefore, when how to solve to track Cetacean using theodolite in the prior art, the placement of pair warp and weft instrument ground important and influential persons
Higher technical problem is sought, as those skilled in the art's important technological problems to be solved.
The content of the invention
In view of this, it is an object of the invention to provide a kind of method for tracking Cetacean, it can be made using this kind of method
Obtain theodolite relatively low to physical features environmental requirement, it is convenient to measure the coordinate information of Cetacean.
The invention provides a kind of method for tracking Cetacean, including：
On the coast A points set the first theodolite, B points set the second theodolite, and measure between the A points and B points away from
From d；
The included angle A between the line between the line and A points and B points between the A points and Cetacean is measured,
Measure the included angle B between the line between the line and A points and B points between the B points and Cetacean；
According to the included angle A, the included angle B and described apart from d, the distance between the A points and Cetacean b1 is calculated
With the distance between the B points and Cetacean b2；
The coordinate information that is measured according to first theodolite and second theodolite and described apart from b1 and the distance
B2, calculates the coordinate information of the Cetacean.
Preferably, it is described apart from d be 200 meters -500 meters.
Preferably, first theodolite is communicably connected with computer respectively with second theodolite, described
The data that computer is measured according to first theodolite and second theodolite, calculate the seat of the Cetacean automatically
Mark information.
In the technical scheme that the present invention is provided, the method that Cetacean is tracked using two theodolites selects A points on the coast
The first theodolite and the second theodolite are placed respectively with B points, and Cetacean point is C points, A, B, C three-point shape triangularity
ABC, measurement obtains the angle A and angle B of triangle, is calculated by solving two theodolites and the triangle ABC of target Cetacean formation
Go out between two theodolites and target Cetacean apart from b1 and b2, target is then obtained according to the coordinate information of two theodolites
The coordinate information of Cetacean, so as to reach the purpose of tracking target Cetacean.It is arranged such, is not related in calculating process
The height distance of theodolite and Cetacean, and then the requirement to environment physical features is relatively low, is convenient for measuring the seat of tracking Cetacean
Mark information.
