In the paper, the specific implementation method for stress detection of steel structures is determined by establishing the mathematical model of photogrammetry and analyzing the finite element theory. Finally, comparison between the stress detection value of steel structures based on photogrammetry and the theoretical value is made. Results show that this method boasts good application value in stress detection of steel structures.
