Intangible cultural heritage(ICH) is an important part of China's excellent traditional culture. Under the background of the new era, it is necessary to shoulder the cultural mission entrusted by the times, play a leading role of intangible culture, and promote the foreign exchange and dissemination of Chinese culture. With the development of modern society, the living environment of ICH has changed, and it is difficult to adapt to modern living conditions, which leads to problems that it has never encountered in the process of inheritance. How to deal with this kind of cultural conflict reasonably and pass on the ICH in an innovative form needs to be considered from the aspects of inheritors, ways of inheritance, audience groups, and so on. If these points and aspects are well combined, a new way can be opened up from the historical development process, which will greatly promote the protection of ICH. In this paper,  Single shot multibox detector(SSD) target detection algorithm based on deep learning technology is further studied. The experimental results show that the accuracy of the improved SSD target detection algorithm map is 5.2% higher than that of the original SSD algorithm, which effectively improves the ability of SSD algorithm to detect targets.
