Abstract

The application relates to a building outer wall leakage detection device and method based on a machine dog carrying an infrared imager, and comprises the following steps: S1: constructing a two-dimensional navigation map with semantic information according to the building map of each floor of a building to be measured, and planning a path; S2: the machine dog autonomously moves to each preset shooting point according to the planned path, and shoots the wall body by using the infrared imager according to a shooting optimization model; and S3: processing the shot infrared image to judge whether the wall body has leakage. The machine dog has the ability to stably work in dangerous and complex environments, through deep fusion of the infrared imager and the machine dog platform, combination of the preset optimal inspection path in the floor and the connection path between the floors, automatic and continuous detection of the building outer wall is realized, and the detection efficiency is significantly improved, and the safety risk and operation cost of manual inspection are effectively reduced.
