The present invention relates to a vision inspection device comprising: a light emitting unit for emitting light toward a first spot of an object; a reflection unit having a first reflection surface facing the object to secondarily reflect the primarily reflected light primarily reflected from the emitted light at the first spot and to emit the secondarily reflected light heading toward a second spot which is a mirrored area of the object; a re-reflection unit having a second reflection surface arranged in the opposite side of the object based on the reflection unit to re-reflect the tertiarily reflected light tertiarily reflected from the secondarily reflected light at the second spot; a camera unit for obtaining the image information of the second spot by receiving the tertiarily reflected light re-reflected in the re-reflection unit; and a processing unit for generating information on the position and shape of the second spot based on the image information of the second spot and information on the position and shape of the first spot. |
