“…In order to quickly and accurately identify and capture the target spot omnibearing in an uncertain area in real time [6] , this paper uses a panoramic camera with a large field of view and image processing techniques such as circle detection, image segmentation and circle fitting to process the sampled images to complete the target spot capture targeting and tracking, and finally build a laser communication APT system based on this image processing algorithm solution. APT system, which can accomplish the pre-processing of 2048 pixel × 2048 pixel images and the detection of the spot position, and finally complete the turn table based on the laser light source accuracy of 0.1° of random pointing, establish and maintain the communication link.…”

In wireless laser communication systems, beam acquiring, pointing, and tracking (APT) technology is the key to establishing and maintaining a laser communication link. In order to solve the problem that the capture cameras used in APT systems usually have a small field of view and are inefficient in scanning the uncertain area and capturing the target spot, which leads to the inability to precisely locate the spot position, an image processing-based omnidirectional laser communication spot image detection technology solution is designed under the condition of using a large field of view of the capture camera, which has the characteristics of strong anti-interference capability and high detection accuracy. Firstly, the block design was simulated on matlab platform, and then the APT system of omnidirectional laser communication was built based on the panoramic camera with large field of view and two-dimensional turntable to verify the scheme. The scheme is implemented in 0.1° steps to sample the laser spot within 180° of the horizontal and tilt directions and obtain the spot coordinates. The spot position information is sent to the two-dimensional turntable through the serial port, and the 0.1° pointing of the turntable to the laser light source is accomplished, which verifies the feasibility and accuracy of the system solution.
