2). The acquisition speed of line scan cameras is faster; the acquisition speed of different types of line scan cameras ranges from 5000 lines per second to 60000 lines per second. Users can choose a few lines or every dozen lines to form a frame of image for processing once , so a very high frame rate can be achieved.
3). The line scan camera can continuously collect and process without interruption; the line scan camera can continuously collect objects that move in a straight line (linear guides, paper, fabric, printed matter, objects on conveyor belts, etc.).
4). The line scan camera has a simpler and more reasonable structure. Compared with area scan cameras, line scan cameras do not waste resolution to capture useless data.
