Abstract:
1. A measuring device configured to measure a height of a mold, the mold supported by a base, the measuring device comprising: a laser generator positioned above the mold, a laser beam emitted by the laser generator substantially perpendicular to a top surface of the mold; a raster positioned between the laser generator and the mold, a laser beam emitted by the laser generator being refracted by the raster to divide the laser beam into two laser beams, the two laser beams cooperatively defining a predetermined angle θ; a camera module positioned above the mold and located between the raster and the mold, the camera module configured to capture an image of the two laser beams irradiated onto the top surface of the mold; and a controller electrically connected to the camera module, the controller configured to receive the image transmitted by the camera module and to calculate an actual distance D between the two laser beams irradiated onto the top surface of the mold, according to the image, the controller being capable of calculating a height H of the mold, according to D and the predetermined angle θ.
