Description
Technical field
The present invention relates to photogrammetry field, and in particular to a kind of interchangeable imaging sensor adapter.
Background technology
Flash ranging is the important exterior measuring means in target range, due to its non-contact, directly perceived, high-precision feature, in range test scape
As having irreplaceable effect in the tasks such as record, Analysis of Abnormal Phenomenon, attitude measurement.But photogrammetry equipment can not at present
Meet simultaneously the high light intensity dynamic range of new weapon test mission, high time resolution, high variable spaces resolution ratio etc. into
As requiring.In section flash ranging at the beginning of target, the light radiation intensity dynamic range of target is big, Spectral Radiation Information is abundant, target detail
It is more, and as the increase of target move distance, the light radiation intensity dynamic range of target will with the detailed information showed
Generation significant changes, existing single complete equipment are not satisfactory to the imaging effect of its overall process.
The optical lens of existing optical measuring device and imaging sensor regular collocation, flexible applicability aspect have much room for improvement.Greatly
The update of bore optical imaging system is slower, and image sensor technologies and image processing techniques progress are maked rapid progress, at present
Both regular collocations make it that the capability improving of photogrammetry systems technology is difficult, it is difficult to it is prominent winged to keep up with all kinds of imaging sensor technologies
The development pushed ahead vigorously, or need to spend substantial amounts of manpower and materials to redesign production new equipment, it can not meet that target range is new advanced
The fast-developing flash ranging requirement of weapon test.
The content of the invention
The present invention provides a kind of interchangeable imaging sensor adapter.The interchangeable imaging sensor be primary mirror with camera it
Between increased one group corresponding camera matching camera lens, the cameras of different target surface sizes is suitable for, in adapter and camera
Connection, and changed in use as a global facility.The interchangeable imaging sensor adapter forms " primary mirror+suitable
Orchestration+polyphaser " structure.Adaptation of the main lens from different imaging sensors is realized, different appoint can be directed to using same primary mirror
Business demand easily changes imaging sensor, makes heavy caliber theodolite synchronous with imaging sensor development level.
Interchangeable imaging sensor adapter includes：One group of adapter, each adapter front end 1 and main lens interface are mutual
Even, each adapter rear end 2 interconnects with the corresponding interface of camera 3；Adapter is consistent with camera quantity；
Adapter, together as global facility, is changed with camera, realizes main lens and different imaging sensors in use
Adaptation.
In order to not influence the picture matter of complete machine while realizing that adapter exchanges, it is real that adapter can take following two schemes
It is existing.
1）The rear end datum clamp face 6 of adapter I is connected with phase machine screw 4, it is ensured that into clear on camera after adapter I is changed
Clear picture；Datum clamp face 6 is positioned with cylindrical pin with internal thread 5 simultaneously, its structure is as shown in Figure 1.This frame mode connection
It is firm, accurate positioning, but need to twist screw during replacing.
2）Adapter II, to realize its quick-replaceable, and is tightened using the structure type of dovetail groove 7 with clamp-screw 8, is made
It is firm that it is connected with camera, as shown in Figure 2.This structure installation is quick, but is easily worn using rear dovetail groove for a long time, causes
Error.
Compared with prior art, the present invention has following clear advantage：
1）Imaging sensor is interchangeable：Flexibly can easily it be replaced with for different task demand using same primary mirror as passing
Sensor, reach the optimum performance to a certain task.
2）Restructural, the reusability of expensive main equipment can be achieved, it is cost-effective.
3）Can with it is most economical, newest imaging sensor is easily used for existing equipment, realize theodolite with imaging
Sensor development level is synchronous.
Brief description of the drawings

Embodiment
The interchangeable imaging adapter of flash ranging camera can realize the quick exchange of different target surface size cameras and different masters
Mirror-camera combination mode designs, and flexibly can be easily replaced with for different task demand as sensing using same primary mirror
Device.Interchangeable imaging sensor adapter can realize the restructural of expensive main equipment, reusability, can be with most economical, easily
Newest imaging sensor is used for existing equipment, realizes that theodolite is synchronous with imaging sensor development level, in target range light
Realize that the imaging of target high quality is significant in survey.
This interchangeable imaging sensor adapter is applicable not only to high dynamic range imaging module hardware structure design, and
Adaptability in high time and spatial resolution image-forming module Design of Hardware Architecture is good.
The interchangeable adapter of camera mainly includes interconnecting with the adapter rear end of camera interface interconnection and with main lens interface
Adapter front end two parts, realize adaptation of the main lens from different imaging sensors, using same primary mirror can be directed to difference
Mission requirements easily change imaging sensor, make heavy caliber theodolite synchronous with imaging sensor development level.
From optical principle, in order to adapt to the camera of different target surface sizes, increase by one group of mirror between primary mirror and camera
Head, corresponding camera matching is allowed to, this group of camera lens corresponds with camera, referred to as adapter.While in order to avoid dividing
The structure of electro-optical device is interfered with primary mirror, and adapter is divided into fore-end and rear end part, and fore-end is in primary mirror and light-dividing device
Between, rear end part is connected with camera, and is changed in use as a global facility.
In order to realize adapter exchange while do not influence complete machine as matter and follow-up image co-registration, take following two
Scheme is realized.
The rear end datum clamp face 6 of adapter I and camera mode connects for screw, it is ensured that into clear on camera after adapter I is changed
Picture；Datum clamp face position is positioned with cylindrical pin with internal thread simultaneously.
Adapter II realizes its quick-replaceable using the structure type of dovetail groove, and with screw-driving, makes itself and camera
It is firm to connect.
Adapter can cause the skew of picture centre in Renewal process, have an impact to successive image fusion.Cause image
The main reason for skew is the skew of the optical axis of the error band of its datum clamp face after adapter is changed.
After the system requirements more changer adapter, the off-centring of image is less than 0.05mm, then controls picture centre skew
Measure is the following aspects：
（1）Axially engaging for spigot surface lengthens as far as possible；
（2）Gapless（Minimum clearance）Structure design；
（3）Adapter is accurately positioned, prevents from producing rotation after changing；
（4）Control the perpendicularity 0.01mm of adapter and datum clamp face, the precision is medium accuracy for machining, energy
Preferably meet technical requirements.
