Plinth data.
In the prior art, dedicated aviation measuring camera has both photo module and exterior orientation data acquisition module, program equipment
Cost is high.Another scheme is that exterior orientation data are directly recorded by system for flight control computer, only needs carry ordinary optical phase
Machine usually executes bat by preset time interval or flying distance output camera control signal by flight control system to control camera
According to, meanwhile, flight control system record is with the matched current exterior orientation data of image data, it can be achieved that cheap aerial survey of taking photo by plane.But by
There are the situations such as focusing is slow, leakage is clapped in camera, the program may cause image and exterior orientation data mismatch.For this problem,
Exterior orientation data record is triggered by camera while can completing to take pictures by ordinary optical camera, guarantees that data are corresponded and kept away
Exempt to be delayed.
In order to using the higher optical camera of product cost in the market, this just need to develop it is a kind of can external camera it is outer
Bearing data acquires signal trigger module, and realizes the system connection for control of taking photo by plane.
Summary of the invention
The sensing terminals such as camera belong to precision equipment, in order not to destroy camera structure, ensure its function admirable, using taking pictures
When indicator light flashing provide exterior orientation data trigger collection signal be effective ways.The utility model discloses one kind for navigating
The camera indicator light signal detection module of bat, used technical solution is:
A kind of camera indicator light signal detection module for taking photo by plane, to detect camera instruction modulating signal and export outer
Bearing data acquisition control signal；The module includes the dielectric base for pasting with camera case, right in the dielectric base
The position of camera indicator light is answered to be equipped with aperture, the upside that the aperture is corresponded in the dielectric base is equipped with total reflection prism,
The light for issuing the camera indicator light enters the total reflection prism by the aperture, from the total reflection after being totally reflected
It gets the side of prism；The exit positions of the corresponding total reflection prism are equipped with light sensitive diode, the light sensitive diode connection
There is back-end circuit；The light irradiation that the light sensitive diode camera subject indicator light issues generates current signal, the current signal by
The back-end circuit detection, and trigger output exterior orientation data acquisition control signal.
Further, the total reflection prism, light-receiving surface are equipped with collector lens.
Further, the collector lens, Fresnel Lenses.
Further, the light sensitive diode, entering light face are plane, as tack light sensitive diode；Its entering light face is tight
Paste the light-emitting surface of the total reflection lens.
Further, all elements in the dielectric base are sealed using black glue.
Using the control system of taking photo by plane of the camera indicator light signal detection module, passed through by system for flight control computer fast
Door line connection camera realizes control of taking pictures；The camera indicator light is equipped with the camera indicator light signal detection module, the phase
Machine indicator light signal detection module takes back flight control system again；Camera indicator light flashing when the camera setting is taken pictures, the camera
Indicator light signal detection module detects that camera indicator light flashes, triggering output exterior orientation data acquisition control signal, the signal
It is transmitted to flight control system, triggering exterior orientation data collect and record, and realize closed-loop control.
The utility model has the following beneficial effects: being designed by reasonable structure, so that camera instruction modulating signal inspection
Module small volume and less weight is surveyed, suitable for using in aerial survey of taking photo by plane, and its horizontal structure is conducive to alignment cameras indicator light and can be with phase
Machine close and firm is pasted；It is avoided that exterior light enters optical path and causes false triggering simultaneously；Optical path energy again is lengthened by total reflection prism
Guarantee that more indicator light light can be pooled to photosensitive element position, promotion signal intensity.The utility model can be using commonly
Optical camera realizes aerial survey of taking photo by plane, and substantially reduces cost, improves take photo by plane interior industry picture mosaic efficiency and precision, has higher practical valence
Value.
