A common practice is to install multiple cameras and supporting light sources at different locations on the visual inspection equipment, sequentially inspecting and capturing images from different product surfaces. However, multiple cameras cannot simultaneously capture images from the same focal point on the same product to be inspected. To achieve this, multiple camera brackets are required to mount the cameras and light sources, which takes up a large installation space and is difficult to install. Utility Model Content
