In engineering construction, each construction period needs accurate measurement of measurement work. Engineering survey is the direct application of surveying and mapping in national economy, social development and national defense construction, and it is also the most extensive application. The most important work of engineering survey is to mark out the data in the construction drawings one by one by using measuring instruments to construct. Its massive data and complex construction environment, however, make the measurement work time-saving, large error and difficult to maintain. With the development of surveying and mapping technology and computer technology, surveying robot comes into being, which is simple to operate and can be completed by one person, thus improving the construction efficiency and accuracy.
