Detailed Description
Fig. 1 is a logic diagram of an automatic tracking shooting system according to a first embodiment of the present invention, where the automatic tracking shooting system includes a control module 11, a pan-tilt system (not shown), a main camera 12 disposed on the pan-tilt system, an auxiliary camera 13, and a narrowband filter 14 disposed in front of the auxiliary camera 13, and the main camera 12 and the auxiliary camera 13 are disposed in close proximity to each other, and their central axes are parallel, so as to ensure that their shooting ranges are nearly the same.
In this embodiment, the auxiliary camera 13 is used to capture an image of a shooting area, where a reference point on a target object in the shooting area has light with a preset wavelength band, the target object is, for example, a person, an animal, an automobile, etc., and the light with the preset wavelength band may be light with a wavelength greater than 760nm (for example, infrared light) or light with a wavelength less than 380nm (for example, ultraviolet light). In addition, the light of the reference point can be directly emitted by a narrow-band light source, for example, an infrared emission tube or an ultraviolet emission tube is arranged on the reference point, and a corresponding fluorescent agent can be arranged on the reference point; the light of the reference point may also be reflected by a reflector, for example, a reflector is arranged on the reference point, a narrow-band light source is arranged elsewhere (for example, beside the auxiliary camera), and the reflector is located within the illumination range of the narrow-band light source.
In this embodiment, the control module is configured to process an image captured by the auxiliary camera 13, and adjust the pan-tilt system to move correspondingly according to a relationship between a position of a reference point in the processed image and a preset position of the lock window until the reference point falls into the lock window.
For example, referring to fig. 2A and 2B, before the automatic tracking, since the narrow-band filter is disposed in front of the auxiliary camera 13, when the auxiliary camera 13 performs the shooting, only the light energy of the preset wavelength band on the reference point of the target object passes through, so that only the reference point 1 can be shot in the image, and then the image is processed. In addition, the preset position of the lock window 2 is located at the center in the image, and the lock window 2 is rectangular. Then, according to the position relationship between the reference point 1 and the locking window 2, the pan-tilt system is adjusted to move correspondingly, for example, in this embodiment, as shown in fig. 2A, the reference point 1 is located at the upper left of the locking window 2, and the pan-tilt system can be controlled to move leftward and upward until the reference point 1 falls into the locking window 2, as shown in fig. 2B. Therefore, when the target object moves, the reference point in the image can be controlled to always fall into the locking window by adjusting the holder system. In addition, the shooting ranges of the auxiliary camera 13 and the main camera 12 are nearly consistent, so that the main camera can be ensured to track the shooting target object all the time.
It should be noted that the above is only one embodiment of the present invention, in other embodiments, the position of the lock window 2 may be preset elsewhere in the image, the user may set the position of the lock window through the user interface, and the shape of the lock window 2 may also be circular, elliptical, hexagonal, etc.
In some cases, because there may be one or more reflection points of the reference point on the target object, in the image captured by the auxiliary camera, besides the image of the reference point, there may also be an image of the reflection point, as shown in fig. 3, 1 is an image of the reference point, 1' and 1 ″ are images of the reflection point of the reference point, respectively, and the brightness of the image of the reflection point is not as high as that of the image of the reference point, in order to achieve accurate tracking, the control module first needs to determine the position of the reference point in the image according to the brightness value, for example, in fig. 3, determine 1 is an image of the reference point, and then adjust the pan-tilt head system according to the relationship between the position of the reference point and the position of the lock window.
Fig. 4 is a logic diagram of a second embodiment of the automatic tracking camera system according to the present invention, which further includes a main display module 15 and an auxiliary display module 16, compared to the embodiment shown in fig. 1.
The control module 11 is configured to superimpose the locked window and the processed image captured by the auxiliary camera. The auxiliary display module 16 is used for displaying the superimposed image, so that a user or a tester can conveniently check the automatic tracking process in real time.
The control module 11 is configured to superimpose the processed image captured by the auxiliary camera with the processed image captured by the main camera. The main display module 15 is used for displaying the superposed images. In this way, the user can see the target object and the reference point in one display screen at the same time, and further, when the determined reference point in the image is found to be inconsistent with the actual situation, the user can correct the situation by reselecting the reference point, and the system can perform automatic tracking again. Of course, in other embodiments, the control module 11 may also superimpose the lock window with the image captured by the main camera and the image captured by the auxiliary camera.
Fig. 5 is a flowchart of a first embodiment of an automatic tracking shooting method according to the present invention, where the automatic tracking shooting method includes:
s1, an auxiliary camera with a narrow-band filter captures an image of a shooting area, wherein the auxiliary camera is arranged close to a main camera, the central axes of the auxiliary camera and the main camera are parallel, a reference point on a target object in the shooting area has light with a preset wavelength band, and the light with the preset wavelength band on the reference point is emitted by a narrow-band light source arranged on the reference point of the target object; or, the light with the reference point having the preset wavelength band is reflected by a reflector arranged on the reference point of the target object;
