“…EF is the flight height h of the UAV, β is the pitch Angle of the CCD [3] , and α is the detection Angle of the CCD. The included Angle between the laser detection direction of CCD and the vertical fixed point direction of CCD is the incidence Angle of the laser, γ is the detection Angle of the laser to the direction of the UAV, and L is the distance between the laser and the target center detected by the UAV [9] . According to the geometric relationship [10] , the following formula can be obtained:…”

With the rapid development of UAV technology, the jamming method of UAV has attracted more and more attention from various countries, which makes the jamming model of laser on UAV detector have been studied deeply.By analyzing the working mode of UAV detector, an equivalent experimental system of laser irradiation optical detector was established in the laboratory environment. The corresponding relationship between pixel saturation and power of detector and the irradiation effect of single beam and double beam laser on detector under different angles were analyzed experimentally. The results show that the saturation spot size of the detector has an approximate linear relationship with the laser incident power, and different saturation interference laser power can be obtained according to the different properties of the sensor. Through the analysis of the established physical model that the incoming power of a single laser varies with the detection Angle, it shows that a single laser only has a certain irradiation effect on the detector below the deflection Angle of 50°. Symmetrical dual laser beam can improve the damage effect of optical detector.

Objective A video stitching method based on dense viewpoint interpolation is proposed to solve the problem of artifacts and defects caused by parallax when stitching under wide baseline scenes. Video stitching technology can facilitate access to a broader field of view and plays a vital role in security surveillance, intelligent driving, virtual reality, and video conferencing. One of the biggest challenges of the stitching task is the parallax. When the cameras' optical centers perfectly coincide, they are unaffected by parallax and can easily synthesize perfect images. However, achieving the complete coincidence of camera optical centers in practical applications is not easy. The cameras are also scattered in some
