Background technique
The size and coral cover of corallite are the most frequently used and basic in coral-reef ecology and Physiologic Studies
Index.Corallite size is the weight that can be used to measure a coral development condition, time-to-live, breeding potential and competitiveness
Biological indicator is wanted, while it is also one of the major criterion for measuring coral growth situation and estimating coral biomass.
There are two types of the indexs of most common corallite size: one is corallites in the case of vertical view on horizontal cross-section
Area as index, but since corallite is irregular, often hemispherical or shape of growing thickly, this is not only that measurement adds difficulty
Degree, while also increasing the error of measurement.Another kind is in the case where vertical view with the longest shaft length of corallite and with it
Vertical axial length is usually directly measured using tape measure or ruler under water as index, and data board or note under water
Record paper identifying recording layer.Entire underwater operation process will be very difficult when having stormy waves or water flow for this kind of method, and needs
Operating time it is longer.
Camera shooting bat is carried out right above coral using the video camera with measurer to the Individual Size measurement of coral at this stage
According to, then by being measured on photo, by ratiometric conversion at actual size.But this measurement method is shot
The angle come is relatively random, more complicated in the conversion process of the longest axis to coral, and to the axis perpendicular with the longest axis
Length is inconvenient for operation by repeatedly measurement and conversion.

Specific embodiment
For the purpose of this utility model, technical solution and advantage is more clearly understood, below with reference to embodiment and attached drawing,
The utility model is described in further detail, and the exemplary embodiment and its explanation of the utility model are only used for explaining this
Utility model is not intended to limit the scope of the present invention.
Embodiment:
Referring to figure 1, figure 2 and figure 3, a kind of measuring scale convenient for the investigation of underwater coral, including rectangle frame 1 are set in rectangle frame 1
It is equipped with graduated scale 2, graduated scale 2 offers through slot 3, the central axes of through slot 3 and the central axes weight of rectangle frame 1 along its length
It closes, 3 two sides of through slot are provided with size scale；Two cunnings that can be slided along one group of opposite side of rectangle frame 1 are provided in rectangle frame 1
Item 4, two draw runners 4 are located at the two sides of graduated scale 2, and two draw runners 4 are parallel with graduated scale 2, two 4 both ends of draw runner
Size scale is provided on the opposite side for the rectangle frame 1 that head is connected；The surface of rectangle frame 1 is provided with carriage 5, platform bracket
With the plane parallel where rectangle frame 1, carriage 5 is fixedly connected by support rod 6 with rectangle frame 1；It is opened respectively in carriage 5
Equipped with ranging hole 7 and camera hole 8, it is provided with rangefinder 9 on ranging hole 7, Underwater Camera 10 is provided in camera hole 8, under water
The camera of video camera 10 is vertical with 5 upper surface of carriage.
In the present embodiment, measuring scale is placed in water, and keeps rectangle frame 1 horizontal positioned, and be located at coral to be measured
The surface of coral adjusts the vertical height of rectangle frame 1 and surveyed coral, makes the figure of the coral shown in Underwater Camera 10 entirety
Image position is in rectangle frame 1.The angle for rotating horizontally rectangle frame 1 makes the longest axis of coral in the image shown in Underwater Camera 10
In the through slot 3 of graduated scale 2；The position for adjusting the draw runner 4 of 2 two sides of graduated scale again, makes the figure shown in Underwater Camera 10
As the coral edge of upper the longest axis two sides is tangent with the draw runner 4 of two sides respectively；Fix after adjusting taking pictures.Survey is utilized simultaneously
Rangefinder 9 measures the distance between focal position and the coral of Underwater Camera 10 H, on the image that video camera 10 is shot under water
Directly read the length h of coral the longest axis1And with the longest axis perpendicular axis length h2, coral is calculated separately out in proportion
The longest axis H1And the perpendicular axis H with the longest axis2Length.
Calculation formula are as follows:
H1=H*h1/d
H2=H*h1/d
Wherein vertical range of the d between rectangle frame 1 and the focus of Underwater Camera 10.
It is flexibly connected between the camera of Underwater Camera 10 and camera hole 8 by bearing, is keeping Underwater Camera 10
Camera position rigid condition under, can be positioned by the longest axis of the rotary bracket platform 5 to coral, evade camera and existed
Biggish movement leads to the problem of focus effects difference, guarantees the clarity of shooting image, significantly smaller measurement error.
Through-hole is offered respectively on one group of opposite side parallel with graduated scale 2 of rectangle frame 1, and bolt 11 is provided in through-hole,
The screw hole to match with the bolt 11 is respectively arranged on two draw runners 4；Bolt 11 is arranged in screw hole, and bolt 11 and institute
It is vertical to state draw runner 4；One end that bolt 11 is located at outside rectangle frame 1 is provided with knob 12, and it is logical that bolt 11 is located at one end in rectangle frame 1
It crosses ball-type articulated joint 13 and graduated scale 2 is hinged, draw runner 4 is adjusted by rotating knob 12, tester is facilitated to grasp
Make；Simultaneously 4 position of draw runner regulated is fixed using screw thread, prevent in shooting process 4 position of draw runner arbitrarily slide.
The upper surface of carriage 5 is provided with air level 14, and tester can pass through observation 14 hollow bubble of air level
Position, distinguishes whether the rectangle frame 1 in shooting process is in horizontality, adjusts in time convenient for operator, guarantees shooting angle
That spends is accurate.
Rangefinder 9 is ultrasonic range finder, mainly by supersonic generator 15, ultrasonic receiver 16 and timer group
At by adjusting making the focal length three of supersonic generator 15, ultrasonic receiver 16 and Underwater Camera 10 be located at same water
In plane；In ranging, the coral that supersonic generator 15 is measured to needs emits a branch of ultrasonic pulse signal, and ultrasonic wave arrives
Reflection a part, ultrasonic receiver 16 are used to receive reflected ultrasonic pulse signal immediately after up to coral；Herein
In the process, timer record supersonic generator 15 emits ultrasonic pulse signal and ultrasonic receiver 16 is received and is reflected back
The time interval t between ultrasonic pulse signal come；Speed v that ultrasonic wave is propagated in water is obtained by tabling look-up, and utilizes public affairs
Formula H=v*t/2 can quickly calculate the distance between focal position and coral of Underwater Camera 10.
