Real-Time Brick Counting for Construction Progress Monitoring
The prevalent method of measuring progress when constructing brick facades is through manual site surveys. These surveys are tedious and time-consuming. They are also approximate, as counting the number of bricks in place to compare against those ordered is a very laborious task compared to its end value. This paper presents a novel and automatic method for counting bricks in place to automate the brick site survey during façade construction. This method works by using images or video frames taken at a construction site. Color thresholds are selected based on the color of the bricks and are used on the video frames to distinguish bricks in the image. The edge map of the frames is generated using a Laplacian of Gaussian filter. The edges are compared with the known brick properties, including their rectangular shape, their expected arrangement and their size. Test results demonstrate that this method is capable of counting the number of bricks on a brick façade with acceptable error.
