In comparison to the standard HD image, the automatic code detection in the 360 camera image appears to improve. The calculated long slope of the crack is 0.8157 and the perpendicular slope is 1.2260. The cracks in the wall are almost fully observed by the algorithm. More examples of crack detection in the 360 camera images are shown in Figure 14. Although the algorithm generally finds the cracks in the surface, most cracks are not fully observed by the algorithm. Further research is necessary to improve the crack detection. However, the examples support the use of a 360 camera for crack detection as the results are similar to the HD camera under the drone.
