Traditional 2D machine vision systems struggle with providing complete information about 3D objects, particularly when height is critical for tasks like inspection and assembly. True 3D machine vision addresses this by capturing width, length, and height data, offering more accurate measurements and revealing hidden features through 3D point clouds. This advancement enhances automation accuracy and usability, overcoming limitations of 2.5D height maps, which can distort information. The integration of 3D imaging hardware and advanced algorithms now allows for better inspection, guidance, and assembly in factory automation, improving overall process efficiency.
