Description
Technical Field
The invention belongs to the field of video monitoring application, and relates to a device and a method for realizing large-range panoramic scanning imaging by using an area array photoelectric detector.
Background
In the field of video monitoring and alarming application, image monitoring is required to be implemented in a large region or large airspace range, and the application has high requirements on technical indexes such as monitoring range, resolving power, sensitivity, alarm response time and the like of a monitoring sensor. On the premise of ensuring the resolution and the sensitivity of the sensor (ensuring the detection distance to a specified target, especially the detection of a small target by a distance of thousands of meters), the realization of large-range scene image acquisition by a scanning method is a main way for expanding the monitoring range.
For area array imaging detectors, such as CCD, CMOS, infrared focal plane, etc., the basic condition for obtaining a good image is to keep the gaze (stationary) of the scene imaging during the exposure (detector light integration, integration time is typically between tens of microseconds and tens of milliseconds), otherwise the image blur may be caused, seriously affecting the detection capability.
Currently, methods for achieving short gaze during scanning are inverse scan compensation and optical multichannel. The inverse scan compensation method sets a scanning mirror with very small inertia in the sensor (camera) optical system, and the mirror can move in the direction opposite to the scanning direction of the camera in the integration time of the detector to compensate the scanning movement, so that the detector obtains a staring scene; during the blanking period of the detector, the reflector is reset, and the preparation for reverse compensation is carried out for the next image exposure. The method has the characteristics of high compensation speed, high requirement on scanning synchronization precision and high technical difficulty. The optical multichannel method adopts a plurality of optical channels with different directions, and images of scenes in different directions on the detector are completed sequentially through light path switching. Is characterized by large volume and is not suitable for long-focal-length long-distance detection system application.
In addition, the traditional camera is driven by a stepping motor to stop and step by step to perform step scanning, in principle, large-range scanning imaging can be completed, but the scanning speed is slow due to the large sensor mass, and particularly when the focal length of an optical system of the camera is increased (the mass of an optical lens is increased) to a certain extent, continuous step impact can cause the power consumption of the system to be increased suddenly, the reliability to be suddenly reduced, and the feasibility of engineering application is influenced.

Detailed Description
As shown in fig. 1, the device for scanning and imaging in a large range of the present invention includes a photodetector array 3, an imaging lens 4 and a reflecting mirror 5 which are sequentially arranged in space, wherein the photodetector array 3 and the reflecting mirror 5 are both arranged on the optical axis of the imaging lens 4, and the reflecting mirror 5 is arranged at an inclined angle with the optical axis 11 of the imaging lens 4, that is, the vertical line in the center of the reflecting mirror 5 maintains a certain angle with the optical axis of the imaging lens 4, the angle ranges from 30 ° to 60 °, preferably 45 °, and the external scene 8 is imaged on the photosensitive surface of the photodetector array 3 after passing through the reflecting mirror 5 and the imaging lens 4.
In order to realize large-scale imaging around the direction of the optical axis 11, the photoelectric detector array 3 is fixed on a first rotating shaft 1 which is arranged coaxially with the optical axis 11, the reflecting mirror 5 is arranged on a second rotating shaft 2 which is arranged coaxially with the optical axis, and the first rotating shaft 1 and the second rotating shaft 2 synchronously rotate to ensure that imaging is carried out on a proper position of a detector photosensor. In order to meet the staring requirement, after synchronous stepping to a set position, the photoelectric detector exposes the set integration time to realize clear imaging. The structure that can be adopted is that both sides of the reflecting mirror 5 are fixed on a frame-shaped reflecting mirror holder 6, and the reflecting mirror holder 6 is fixed on the second rotating shaft 2 and rotates around the second rotating shaft 2.
Fig. 1 shows a specific embodiment of a periscope structure, in which the optical axis is vertical, and the light of an external scene 8 is reflected downwards by a reflector 5 and imaged on the photosensitive surface of a photodetector array 3 by an imaging lens 4, so that a wide-range imaging around the optical axis direction can be realized. In practical application, the reflecting mirror 5 and the photoelectric detector array 3 synchronously rotate under the drive of the stepping motor, and the scanning in a certain sector area is completed and then reversed. If the panoramic view or the continuous scanning exceeding 360 degrees is required to be completed, a collecting ring is required to be arranged between the photoelectric detector array 3 and the first rotating shaft 1, so that the power supply and the signal output of the detector are realized. The photodetector array 3 may be an area array detector or a line array scanning detector, so long as imaging in the field of view is satisfied. Since the heavier imaging lens 4 is kept stationary, only the light-weighted mirror 5 and the photodetector array 3 are rotated, so that under the condition of compact structure, rapid stepping can be realized, and the stability of the system is maintained.
Fig. 2 shows a further modified embodiment, in which an angular swinging mechanism is provided on the mirror holder 6 to drive the mirror 5 to swing, so as to realize a change in the tilt angle between the mirror 5 and the optical axis 11. The angular swinging mechanism can take a variety of configurations, only one of which is shown in the present embodiment. The angle swinging mechanism comprises a swinging motor 7 and a bearing 9, two side edges of the reflecting mirror 5 are correspondingly provided with two coaxial swinging rotating shafts 10, one swinging rotating shaft 10 is fixed on the reflecting mirror frame 6 through the bearing, the other swinging rotating shaft 10 is fixedly connected with the rotating shaft of the swinging motor 7, and the swinging motor 7 is fixed on the reflecting mirror frame 6. The angle swinging mechanism can adopt other modes of driving other mechanisms by a motor, so long as the pitching angle adjustment of the reflecting mirror 5 can be realized, and a swinging mechanism with light weight and small moment of inertia is selected in the implementation.

The third step is that the pitching mechanism begins to swing, the inclination angle between the reflecting mirror 5 and the optical axis 11 is changed, for example, 0.1 degrees, after each swinging unit, the angle is kept unchanged, then the detector and the reflecting mirror 5 rotate about the optical axis 11 by an angle unit, for example, 1 degree, and the photo detector array collects the image signals recorded at the position; when the 360-degree or fan-shaped angle rotation scanning is completed, the pitching mechanism swings to the next angle again, the steps are repeated until the scanning from the swing starting point position to the swing end point position is completed, and the wide-range view field imaging is realized.
