Research on the Appearance Size Detection Method of Highway Engineering Based on Tilt Photography Technology

Based on the application research of UAV tilt photogrammetry technology in highway engineering design and construction compliance detection, this paper changes the shortcomings of traditional detection with low efficiency, poor overall evaluation level and high cost, and provides a new high-efficiency, high-precision and low-cost highway engineering design and construction compliance evaluation and detection method for design units. After constructing the inclined real scene model for the aerial photography of the test section of Uma expressway, the new LSV drawing software is used to integrate the three-dimensional real scene model with the design CAD drawing, extract and measure the virtual 3M ruler measurement method, EPS conversion two-dimensional model, and extract and measure the appearance storage quality inspection index in the standard for quality inspection and evaluation of Highway Engineering - Civil Engineering (JTGF80/1-2017). The advantages of the new system are verified by comparing with the traditional compliance detection in terms of index coverage, detection accuracy and cost. It provides a reference for the further study of highway engineering design compliance evaluation in the later stage.
