Claim 0:
1. A powder leakage monitoring device, characterized by comprising:
light field camera, used to record original light field image of monitored area;
3D PTZ (3-Dimensional Pan/Tilt/Zoom), arranged under the light field camera, is used to rotate in a set direction to adjust a shooting angle of the light field camera, so that the light field camera is aligned with the monitored area;
computer, respectively connected to the light field camera and the 3D PTZ, is used to generate a refocused image corresponding to the original light field image, and determine spatial coordinates of pneumatic conveying dust leakage point in the monitored area and the hazard range of dust leakage, basing on the refocused image and the shooting angle.
