Abstract
The invention discloses a method for correcting ranging swing errors of a watchtower, and relates to the technology for improving an optical ranging method of the watchtower. A mounting platform is fixed on the top of the watchtower, and an optical ranging mechanism comprises a monitor camera and a lens component thereof, a holder, a uniaxial high-precision angular transducer and the mounting platform; when optical ranging is performed, the uniaxial high-precision angular transducer is used for measuring a swing angle of the fire-proof watchtower, and transmitting measurement data at a certain moment to a computer; the computer is used for correcting errors of the optical ranging measurement data according to the swing angle of the fire-proof watchtower. According to the method, the problem of overlarge positioning precision error caused by swing due to the fact that the positioning operation of an alarm location is completed by an elevation angle measured by the holder in current optical ranging of a fire-proof early warning and monitor system can be solved.
Description
Technical field
This invention She is Ji the improvement technology of sightseeing tower optical ranging method.
Background technology
The location of adopting optical range finding unit to finish place of alarm in the fire prevention prewarning monitoring system.The design standards of fire tower all is pedestal and body of the tower chain connection, and body of the tower can be swung by windage, because the bearing accuracy error that stagger is brought has reached 4000 meters-4300 kilometers.
Summary of the invention
The invention provides Yi Zhong sightseeing tower range finding stagger modification method, the invention solves the location that present fire prevention prewarning monitoring system optical range finding unit finishes place of alarm, stagger is excessive, causes the excessive problem of bearing accuracy error.
For addressing the above problem, the present invention adopts following technical scheme: sightseeing tower range finding stagger modification method sightseeing tower top fixed installation platform 4, consists of optical range finding unit by rig camera and lens assembly 1, The Cloud Terrace 2, single shaft high-precision angle sensor 3 and mounting platform 4; Single shaft high-precision angle sensor 3 is installed in the rotor (guard shield) 1, and sensor single shaft axis is parallel to range finding optical axis axis, and the base of The Cloud Terrace 2 is fixed in above the mounting platform 4, and rig camera and lens assembly 1 are installed in above the rotor of The Cloud Terrace 2;
When optical ranging, single shaft high-precision angle sensor 3 records the depression angle that angle is exactly range finding, and sends computing machine to the measurement data in a certain moment, and computing machine carries out distance calculation according to recording angle.
The present invention provides a cover to solve the device of positioning error technically.
The optical axis depression angle angle that the present invention records with passback by the single shaft high-precision sensor, computation in range finder is calculated is finished range finding.The present invention can revise according to the digital tripod head pitch angle data and calculate the error that is caused by swing, the measuring accuracy of Ti Gao sightseeing tower range finding.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is optical ranging schematic diagram of the present invention.
Symbol description among the figure: rig camera and lens assembly 1, The Cloud Terrace 2, single shaft high-precision angle sensor 3, mounting platform 4.
Embodiment
The below is described in detail the present invention with best embodiment.
Sightseeing tower range finding stagger modification method,
As described in Figure 2, optical ranging principle: F: optical range finding unit's measuring distance of target point; α: position angle (with the direct north drift angle) obtained by digital tripod head; β: the angle of pitch (optical range finding unit's optical axis water and plane included angle); δ: the angle of pitch that the The Cloud Terrace records (angle of optical range finding unit's rotation and optical range finding unit's rotation; P: infield; φ: mounting points geographic coordinate longitude; λ: infield geographic coordinate latitude; Hb: mounting points geographic coordinate elevation; H: setting height(from bottom); T: the optical range finding unit installation place (being installed on pylon or other stilts) that is positioned at the top, infield; TO: optical range finding unit's rotation (perpendicular to surface level); OF: the distance that need to record; TF: optical range finding unit's optical axis.L=ctan（δ）（H+h）。The δ angle value that participates in calculating is recorded by the single shaft angular transducer, can revise The Cloud Terrace in being applied to calculate.
The correction of ， sightseeing tower range finding stagger consists of optical range finding unit by rig camera and lens assembly 1, The Cloud Terrace 2, single shaft high-precision angle sensor 3 and mounting platform 4 as shown in Figure 1; Rig camera and lens assembly 1 are installed in the protective cover, the mounting platform 4 solid sightseeing tower tops that surely are installed on; Single shaft high-precision angle sensor 3 is arranged at above the mounting platform 4, and the base of The Cloud Terrace 2 is fixed in above the mounting platform 4, and rig camera and lens assembly 1 are installed in above the rotor of The Cloud Terrace 2.
It should be noted that at last: obviously, above-described embodiment only is for example of the present invention clearly is described, and is not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And the apparent variation of being amplified out thus or change still are among protection scope of the present invention.
