Object features detection under the small space of arrival is examined in the detection of aerospace, automobile, the energy and industrial equipment and failure
It is disconnected that fields is waited to have urgent application demand.However, since most of measuring system volume is larger, it is few to be suitable for narrow space
In the miniaturization of measurement, ultrashort coke sighting device.In recent years, using optical touchless method come detection object characteristic information
As research hotspot, but difficulty be to be difficult to find in narrow space or irregular container an accurate reference planes or
It is difficult to make the volume constriction of object being measured to adapt to actual measurement condition.On the other hand, vision measurement location technology is with image
It combines closely for the carrier and computer technology of information, there are the spies such as non-contact, comprehensive rapid survey positioning, high-precision
Point, oneself is widely used in various measurement tasks.Therefore a kind of miniaturization, ultrashort burnt to object features detection etc. is studied
The device of practical operation is of great significance.
Summary of the invention
The present invention provides one kind can place in narrow spatial dimension, and to ultrashort focal length (being less than 5mm) range
Interior object carries out the ultrashort burnt visual imaging detection device of miniaturization of imaging observation.Technical solution is as follows:
A kind of ultrashort burnt visual imaging detection device of miniaturization, including imaging unit, at least one microlens array unit,
Lighting source, image processing module and display module, which is characterized in that after each microlens array splicing is integral, splicing
Periphery afterwards arranges that lighting source, spliced microlens array are directly fitted with imaging unit.
Preferably, microlens array unit each unit face shape is consistent, is smooth surface, and bore shape one
It causes.The lighting source is LED light source or white light source.
The scheme provided in the embodiment of the present application at least has the following technical effects or advantages:
(1) using design is integrally formed, overall dimensions are smaller (thickness about 20mm), frivolous firm；
(2) smaller operating distance (being less than 5mm) realizes that figure is adopted in the large area shooting of high quality high speed in narrow space；
(3) variance factor is few, saves adjustment time, reduces overall cost；
For wherein core component microlens array, it is bonded to realization miniaturization imaging with imaging unit, passes through combination
The form of splicing may be implemented the ultrashort burnt visual imaging detection of thin and large area, by subsequent image synchronous acquisition, and spell
Processing is connect, separate imaging image is synthesized, achieve the effect that very big region (number meter Chang Du) while being detected.
