Due to the high overlap of sampling nodes of UAV aerial image, the problem of pixel wrong matching cannot be avoided in the process of UAV aerial image registration. A control technology of UAV aerial image registration process based on neighborhood consistency is proposed. According to the criteria of UAV aerial image registration area, the key image annotation points are identified, and the UAV aerial image fusion method based on neighborhood consistency is designed by calculating the consistency measure index. According to the numerical level of sampling gray factor, the overlapping relationship between image sampling nodes is analyzed, and the aerial image is subjected to coordinate transformation and geometric correction. Combined with the coordinate transformation and geometric correction results, the image boundary feature points are extracted, and the feature points are used as the registration process control points. The UAV aerial image registration process is controlled according to the distribution quality of control points and the extreme value of scale space. The experimental results show that under the principle of neighborhood consistency, the overlap between UAV aerial image sampling nodes is significantly reduced, the problem of pixel error matching is solved, and the registration effect is good.
