The servo turntable is composed of an azimuth axis servo motor, a pitch axis servo motor, and a mechanical bracket.

[0041] The laser cannon is installed on a collapsible tripod and can identify, track, and damage a target through automatic or manual tracking methods. For automatic tracking, the image sensor captures an image to calculate the target miss distance, and information such as the target speed and acceleration is obtained from the miss distance. Then, the servo turntable is controlled to perform corresponding following movements to achieve rough tracking of the target. At the same time, according to the feedback information of the miss distance, the two-dimensional galvanometer is driven to perform fine tracking of the target to achieve aiming and locking of the target.

[0042] For manual tracking, mainly through a keyboard or a joystick and using the signal receiving module to send signals to the servo turntable to control the movement of the turntable to achieve rough tracking of the target. The image sensor captures an image to calculate the target miss distance, and the two-dimensional galvanometer is driven to perform aiming and locking of the target.

It has a higher degree of intelligence and can realize automatic target recognition, tracking and aiming, and striking. It can realize unmanned defense and multi-unit joint area defense. The control method is more diverse and can be applied to a wider range of application environments. It has a higher output optical power and can quickly damage unmanned aerial vehicles to achieve good striking effects.

[0044] As Figure 2 shown, in some embodiments, the working process of the laser cannon includes: capturing a target image through the image sensor; according to the target image, using the servo turntable to perform rough tracking on the target and using the two-dimensional galvanometer to perform fine tracking on the target to achieve aiming and locking of the target; measuring the distance between the laser cannon and the target through the laser rangefinder, and adjusting the focal length of the optical lens group according to the distance to achieve adjustment of the laser emission focal length.

[0045] In some embodiments, the rough tracking of the target by using the servo turntable includes: calculating the miss distance of the target through the image processing unit, and calculating the speed of the target in each direction according to the miss distance; controlling the azimuth axis servo motor and the pitch axis servo motor to rotate, and adjusting the azimuth axis angle and the pitch axis angle to achieve rough tracking of the target.

[0046] In some embodiments, the fine tracking of the target by using the two-dimensional galvanometer includes: calculating the miss distance of the target through the image processing unit, and calculating the target angle deviation according to the miss distance; transmitting the target angle deviation to the two-dimensional galvanometer drive control circuit, and controlling the two-dimensional galvanometer to perform fine tracking on the target.

[0047] The laser rangefinder is used to measure the distance between the laser gun and the target, and the optical lens group is used for collimation, beam expansion and focusing of the laser. The optical lens group is installed on the motor and the guide rail, and the relative position of the lens group on the guide rail is adjusted by controlling the rotation of the motor, so as to adjust the focal length of the optical lens group to realize the adjustment of the laser emission focal length.

[0048] The laser emitter is installed on a two-axis turntable module composed of two servo motors. The emitter and the turntable module are fixed by screws or slot structures (including but not limited to these two methods). The base of the turntable module group is installed on a collapsible tripod, and the two are fixed by screws and nuts or slot methods (including but not limited to these two methods). The laser light source and the emitter are connected by an optical fiber.

[0049] During specific implementation, the power is turned on, and the image sensor starts to capture images. After the target is recognized, the miss distance of the target is calculated through the image processing unit, the miss distance is analyzed through an algorithm, the speed of the target in each direction is calculated, the motor speed is obtained through calculation, the signal is transmitted to the motor driver, the motor is controlled to rotate, and the azimuth axis angle and the pitch axis angle are adjusted to achieve rough tracking of the target.

[0050] At the same time, the target angle deviation is calculated according to the miss distance, the angle information is transmitted to the two-dimensional galvanometer drive control circuit, and the two-dimensional galvanometer is controlled to perform fine tracking on the target and lock the target. The laser rangefinder measures the distance between the target and the laser gun in real time, calculates the motor for adjusting the focus of the emitted laser through the distance, changes the relative position of the optical lens group on the guide rail, and realizes the real-time adjustment of the focal length of the emitted laser, so that the emitted light has a smaller light spot to ensure energy concentration and cause faster and more effective strikes on the target.

[0051] Among them, during the working process, the power supply powers the laser, the laser converts electrical energy into light energy, the laser is collimated by the collimator and then irradiated on the two-dimensional galvanometer, and after being reflected by the two-dimensional galvanometer, it passes through the optical lens group and finally exits from the lens to form the emitted laser.

[0052] During the process of target recognition and tracking, the image sensor captures images in real time and transfers the images to the image processing unit. Through the internal algorithm of the image processing unit, calculations are performed to obtain the target miss distance. Based on the miss distance, the angular deviations of the target in the X and Y directions are calculated. The image processing unit transfers the deviation information to the two-dimensional galvanometer driver to drive the galvanometer to perform angular compensation in two directions, achieving precise tracking of the target.

[0053] During the process of target recognition and tracking, the laser rangefinder measures the distance between the target and the laser cannon in real time and transfers the distance information to the image processing unit. The image processing unit calculates the focal length of the outgoing light and the distances between various lenses based on the distance information. According to the above information, the movement direction and movement distance of the lead screw motor are calculated, and the parameters are transferred to the lead screw motor driver to drive the motor to achieve real-time focal length control, enabling the system to have the best striking effect.

[0054] During the process of target recognition and tracking, the image sensor captures images in real time and transfers the images to the image processing unit. The image processing unit calculates various required parameters and sends the parameters to the corresponding servo motor driver and two-dimensional galvanometer driver to drive the motor and the two-dimensional galvanometer to perform target tracking and locking, achieving automatic tracking and locking of the target.

[0055] Through a wired or wireless control method, signals are transmitted to the signal sending and receiving module using a keyboard or joystick to control the servo turntable. The azimuth and elevation motors inside the turntable respond accordingly to achieve rough tracking of the target. During the process of target recognition and tracking, the image sensor captures images in real time and transfers the images to the image processing unit. The image processing unit calculates various required parameters and sends the parameters to the two-dimensional galvanometer driver to drive the two-dimensional galvanometer to perform precise tracking of the target, achieving manual tracking and locking of the target.
