Abstract
An image motion compensation mechanism of an aerial camera belongs to the application of a nano-drive precision positioning technology in the aerial camera. The device is characterized in that a CCD camera (2) is arranged in a guide rail (3) above a photographic objective (4) and can move along the axial direction, one end of a piezoelectric ceramic driver image motion compensation mechanism (1) is fixed on a base (6) connected with the photographic objective (4), and a spherical surface (5) at the other end forms point-surface contact with the CCD camera (2). The device has the advantages of high positioning precision, high response speed, high resolution, small volume, good stability, no idle stroke and the like.
Description
The utility model is a kind of IMC mechanism of aviation measuring camera, belongs to nanometer and drives the applied technical field of precision positioning technology in the aviation measuring camera system.
IMC in the past:
The one, the mode of employing mechanical compensation.Promptly adopt the step motor drive cam mechanism, promote CCD camera or sensor and carry out IMC.Because defectives such as the friction of physical construction existence itself, wearing and tearing, gaps, cause phenomenons such as low-response, resolution are low, in fact often its IMC effect is unsatisfactory, and mechanism and bulky.
The 2nd, the mode of employing software processes.Promptly the degeneration image that is caused by image drift that the CCD camera is taken carries out software processing and realizes IMC.Though this IMC method has been avoided the negative effect that defective caused of physical construction itself, but the success or not of its image processing is subjected to directly influencing of noise treatment quality, simultaneously in the process of handling, the recovery image that also occurs pathosis easily will be prevented unusual processing at any time.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art and a kind of IMC mechanism that provides, adopt the piezoelectric micro-displacement actuator of good rigidly, promote the CCD camera and realize IMC as micro-displacement, make at the picture of time shutter internal object static with respect to sensor, thereby guarantee the image of under the situation of any one grade of time shutter, being taken photo by plane clearly.
The purpose of this utility model can reach by following measure: the CCD camera places the guide rail of photographic field lens top, and but along continuous straight runs moves, one end of piezoelectric ceramic actuator IMC mechanism is fixed on the pedestal that connects photographic field lens, and the sphere of the other end forms the some face with the CCD camera and contacts.
The purpose of this utility model can also reach by following measure: an end fixed bonding of the piezoelectric micro-displacement actuator of piezoelectric ceramic actuator IMC mechanism is on pedestal, the bonding metal driving plush copper of the other end is stretched out the stomidium that is fixed in the protective cover on the pedestal, embedding in the top groove of metal driving plush copper has a steel ball, forms the some face with the CCD camera and contacts; There is disk spring on the stomidium limit of metal driving plush copper and protective cover.
Description of drawings:
Fig. 1 is the installation site synoptic diagram of the utility model on aviation measuring camera.
Fig. 2 is the IMC mechanism map of piezoelectric actuator.
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1: CCD camera (2) places the guide rail (3) of photographic field lens (4) top, one end of piezoelectric ceramic actuator IMC mechanism (1) is fixed on the pedestal (6) that connects photographic field lens (4), and the sphere of the other end (5) forms the some face with CCD camera (2) and contacts.Upward along heading (7) do micro-displacement by sphere (5) and CCD camera (2) at track (3) by piezoelectric ceramic actuator IMC mechanism (1), make CCD camera (2) photograph the image of taking photo by plane clearly by photographic field lens (4).
As shown in Figure 2: an end of piezoelectric ceramic actuator (8) is bonded on the pedestal (6), and the bonding metal plush copper (9) of the other end is stretched out the stomidium of protective cover (11), and the steel ball sphere (5) that metal driving plush copper top embeds forms the some face with CCD camera (2) and contacts; Constitute a rigidity reinforcing mechanisms by disk spring (10) and protective cover (11), strain and be fixed on the pedestal (6), form a protection cavity that does not influence piezoelectric micro-displacement actuator (8) displacement to pedestal (6) direction; Piezoelectric micro-displacement actuator (8) is done micro-displacement by the drive point promotion CCD camera (2) of steel ball sphere (5) along heading (7) with respect to pedestal (6), thereby reaches the purpose of IMC.
The utility model is compared prior art and is had following advantage:
1. adopt good rigidly, good linearity, hysteresis is little, displacement is big piezoelectric ceramics micrometric displacement Driver is done IMC mechanism, and promote the CCD camera and in the process of taking photo by plane, carry out IMC, So that static with respect to sensor at the picture of time for exposure internal object, thereby guarantee any one Obtain clearly Aerial Images in the situation of shelves time for exposure. Its positioning accuracy height (nm level), Fast response time (＜1ms), and resolution ratio height (nm level), volume is little, repeatability and stable Property is good, no-idle running. 2. piezoelectric micro-displacement actuator is placed the protective cover of disk spring, greatly Strengthened the rigidity of piezoelectric micro-displacement actuator, so that it has in the process of taking photo by plane Higher precision. 3. owing to the existence that this rigid protective cavity is arranged, so that the piezoelectric ceramic actuator IMC Mechanism is not subjected to external interference, especially takes off when dropping on the runway high speed slide, The strenuous vibration that takes place is to the damaging influence of piezoelectric ceramic actuator, played necessary Protective effect.
Claims (3)
1. the IMC mechanism of aviation measuring camera, it is characterized in that CCD camera (2) places the guide rail (3) of photographic field lens (4) top, and can move vertically, one end of piezoelectric ceramic actuator IMC mechanism (1) is fixed on the pedestal (6) that connects photographic field lens (4), forms the some face with the sphere (5) and the CCD camera (2) of the other end and contacts.
2. aviation measuring camera IMC as claimed in claim 1 mechanism; an end fixed bonding of piezoelectric micro-displacement actuator (8) that it is characterized in that IMC mechanism is on pedestal (6); the bonding metal driving plush copper (9) of the other end is stretched out the stomidium of the protective cover (11) that is fixed on the pedestal (6); embedding in the top groove of metal driving plush copper (9) has a steel ball (5), forms the some face with CCD camera (2) and contacts.
