background knowledge

As a key component of the internal air purification of the car, the existence of the edge burr may destroy the sealing of the filter paper, leading to the unfiltered air and pollutants entering the compartment, affecting the air quality in the cockpit, and then affecting the health and driving safety of passengers. The 3D wire laser camera can accurately detect and quantify the burr size, ensure the sealing effect of the filter element, and maintain the efficient operation of the air conditioning system.
