    Abstract: At present, image recognition technology first classifies images and outputs category information through the neural network. The next step involves the search. Before retrieval, the feature database needs to be established, followed by one-to-one correspondence. This method is tedious, time-consuming and has low accuracy. In computer vision research, researchers have proposed various image recognition methods to be applied in various fields and made many research achievements. However, at present, the accuracy, stability and time efficiency cannot meet the needs of practical work. In terms of UAV image recognition, high accuracy and low consumption are required. Previous methods require huge databases, which increases the consumption of UAVs. Taking aerial transmission and line images as the research object, this paper proposes a method of image recognition based on chaotic synchronization. Firstly, the image is used as a function to construct a dynamic system, and the function structure and parameters are adjusted to realize chaos synchronization. In this process, different types of images are identified. At the same time, we research this dynamic system characteristics and realize the mechanism of image recognition. Compared with other methods, the self-built aerial image data set for bird's nest identification, iron frame identification and insulator identification has the characteristics of a high identification rate and less calculation time. It is preliminarily proven that the method of synchronous image recognition is practical, and also worthy of further research, verification and analysis.

    Abstract: Unmanned aerial vehicle automatic fault identification of high voltage transmission equipment has entered the stage of product development, in which image recognition technology is one of the key technologies. There are often bird nests on the high voltage transmission tower, which have an impact on the transmission, so they needs to be automatically detected. Methods: For bird's nest recognition, a novel algorithm is proposed. Firstly, the template image and auxiliary function are used to construct the system, and the iterative point trajectory set, called feature set, is obtained by iteration; Then, the target image is searched by blocks, and the image blocks are iterated with the same auxiliary function to construct the iterative system, and the set of iterative point tracks to be identified is obtained. The correlation coefficient is calculated by comparing the feature set with those to be recognized. And we can confirm whether the image block is a bird's nest according to the size of correlation coefficient. Results: Different from the general image recognition method, the iterative algorithm obtains the iterative trajectory by iterating the image and the auxiliary function, and takes the iterative trajectory as the image feature, then the feature comparison is carried out, so as to achieve the goal of bird's nest recognition. The effectiveness of the method is proved by experiments. The recognition accuracy is 99% by experiment on the self-built data set. Conclusion: This paper proposes a new feature extraction algorithm for bird's nest recognition. The algorithm based on iteration is very simple and effective for bird's nest identification. As a new method, it needs further development and improvement.
