3. Question At an airport, an air cargo transport company wishes to quickly and easily measure the size and shape of airfreight on pallets, prior to loading the pallets into aircraft (under the passenger seating area - as shown in Figure 03). They have approached a machine vision company to produce a system for measureing the airfreight. Required performance for the system includes: Measure the object size and shape as accurately as possible, up to a maximum base size of 3 x 2.5 metres and height of 2.5 metres. Maximum system camera height is 4.5 metres. System to operate in a warehouse environment, where significant changes in background light occur (although the system will not be subjected to direct sunlight when in use) Provide a detailed recommendation to the carrier of how they should approach the system development. As part of this, give camera, lens, lighting and other technical recommendations that will enable them to realise the required performance. Include diagrams/sketches that show how you could arrange and configure the required equipment. Explain what machine vision techniques you would use to measure the size and shape of the palletised airfreight. Try to address any practical problems that would arise. For example, if you employed 1 camera directly above the object, and if the latter were tall (e.g. close to 2.5 m) and quite wide, camera occlusion would mean that the sides of the object would not be visible - so if protrusions were present in the sides, they would not be visible. Suggest methods for overcoming this potential problem (and any other potential problems you can think of). Be as specific as possible and where possible recommend specific components and machine vision methods (e.g. make recommendations about the make and model of cameras)
