Description
Technical field
The present invention relates to a kind of camera system, be specifically related to a kind of racemization camera system, be mainly used in the object of two relative rotary motion, take and write down the working condition of another rotating object, belong to image processing field by rotating object.
Background technology
For an object A that rotation takes place to separate in motion process, in the time of need taking and write down the motion conditions after separating, many at present employing camera systems are directly taken, but the carrier of camera system---object B is also in rotation, make that photo and the image of directly taking gained are very fuzzy, cause to discern, accurately writing down the motion conditions of object A, be unfavorable for that the technical staff carries out analyzing and processing afterwards.
Therefore, the technical staff adopts software compensation that the blurred picture that aforesaid way obtained is reduced, but the effect of this method is unsatisfactory, the situation that has image fault, and such software is comparatively complicated, and the cost height does not fundamentally solve the fuzzy problem of image and video.
Summary of the invention
The invention provides a kind of racemization camera system, mainly solved existing camera system when existing relative rotary motion to take with target, the image of taking is very fuzzy, the following adopted software compensation carry out image restoring the method weak effect, have the problem of image fault.
Concrete technical solution of the present invention is as follows:
This racemization camera system comprises controlling organization and image mechanism, it is characterized in that: described controlling organization comprises microprocessor and motor drive module; Image mechanism comprises shell, camera head, conducting slip ring, rate gyro unit, motor and bearing; Camera head is arranged in the shell, and camera head is connected with conducting slip ring one end, and rate gyro unit is arranged at other end inside, and rate gyro unit is electrically connected with microprocessor, and camera head is arranged on its motor rotating of control, and motor passes through bearings; Motor drive module is electrically connected with microprocessor, and the control motor speed also provides voltage for motor.
Described rate gyro unit is used to measure the rotating speed of camera lens; Described microprocessor is used for the rotating speed of inbound pacing gyro to measure and handles, and to the closed-loop control of motor drive module output control signal, regulates camera head by the motor rotation then.
Described camera head comprises optical lens and connected image detector.
Described motor is a direct current torque motor, and camera head is connected with axle in its motor rotating of control.

The invention has the advantages that:
The present invention adopts the form of mechanical structure compensation to realize racemization.The racemization camera system is installed on the back of the rotating object B that will separate, carries out the rotation of about 720 °/s with rotating object B.
The present invention obtains the rotating speed of rotating carrier B by built-in rate gyro unit, and carries out same speed by the driven by motor camera head and rotate, and eliminates the relative rotary motion that exists between rotating carrier and camera head with this, and compensation image drift effect makes it can obtain picture rich in detail.
Racemization camera system provided by the invention is used for the Aeronautics and Astronautics field, has satisfied the adaptive strict demand to volume weight and environment.Especially mechanical environment will bear the vibration and the impact of relatively large level.This racemization camera system can be in harsher mechanical environment, eliminates rotatablely moving of carrier and obtains picture rich in detail, and for the effective course of work of object observing provides effective foundation, result of the test can satisfy instructions for use.Can obtain the detailed situation in the two articles separation process in rotatablely moving, for failure diagnosis and scrap build provide foundation.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a control system block diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is described in detail, as shown in Figure 1 and Figure 2:
This system comprises controlling organization and image mechanism, and controlling organization comprises microprocessor and motor drive module; Image mechanism comprises shell, camera head 1, conducting ring 4, rate gyro unit 5, motor 3 and bearing 2.
Rate gyro unit is used to measure the rotating speed of the object that the racemization camera system is installed, for the control that realizes the camera lens rotating speed provides given and feedback; Microprocessor is used for the rotating speed of inbound pacing gyro to measure and handles, and then to motor drive module output control signal, regulates the rotating speed of camera head by the motor rotation.
The principle of this institute of system foundation is as follows:
1, detects the rotating speed of the object that loads the racemization camera system, generally adopt rate gyro unit to measure;
2, regulate the rotating speed of camera head
Because camera head is arranged in the object that loads the racemization camera system, when loading the object rotation of racemization camera system, camera head also is rotated, when the camera head of rotation is taken, the image that is obtained is very fuzzy, need the rotating speed of camera head is eliminated, promptly camera head is static with respect to the earth;
The rotating speed of the object of the installation racemization camera system that rate gyro unit is recorded transfers to microprocessor, draw camera head with respect to the static rotating speed that needs compensation of the earth, by microprocessor this rotating speed is converted to the compensating rotational speed signal and transfers to motor drive module, motor drive module rotates according to the compensating rotational speed signal drive motor; The rotation of driven by motor camera head is regulated the rotating speed of camera head;
3, obtain image
Obtain the picture rich in detail that is lower than 10 °/s after the rotating speed compensation; When the rotating speed of the object that the racemization camera system is installed changed, repeating step 1,2 was regulated, and makes the image that obtains be lower than 10 °/s.
The present invention adopts the form of mechanical structure compensation to realize racemization.The racemization camera system is installed on the back of the rotating object that will separate, and carries out about 2 revolutions per seconds rotation with rotating object.
During concrete the application, general camera system can adopt following leading indicator: the angle of visual field: diagonal 45 ± 5 degree; Camera distance: 1m～100m; Video standard: CCIR, 25FPS; Pixel number: 〉=512 * 582; Differentiate and require: object distance 1m place, distinguishable 50mm * 50mm object; Image effect: the image rotating speed is lower than 10 degree/s.
