Conveyor belt vibration can only be minimized, not completely avoided
[0009] The current visual detection device for the appearance of cigarette packs adopts a two-dimensional detection and measurement method, but the position of the cigarette pack relative to the camera changes in a three-dimensional space. A two-dimensional tool with a large projection measurement error is used to detect a three-dimensional swinging cigarette pack. , it is difficult to meet the measurement requirements of millimeter precision

The invention discloses a cigarette packet appearance three-dimensional visual detection method and device, and belongs to the field of cigarette detection. The device comprises a cigarette packet conveying belt, a right side guide steel wire, a left side guide steel wire, a lower right side guide plate, a lower left side guide plate, a light source, a front camera, a rear camera, a trigger sensorI, a trigger sensor II, a parallax camera set, a three-dimensional visual processor, a controller, a rejection unit, a lens assembly and an imaging element. The two cameras are adopted to carry out parallax shooting and parallax three-dimensional visual processing on cigarette packets at the same time to obtain three-dimensional measurement data and detection results of the cigarette packets, sothat the detection and measurement precision of the cigarette packets is effectively improved, the missing detection and rejection of unqualified cigarette packets are obviously reduced, and mistakenrejection of qualified cigarette packets is reduced.
Description
technical field [0001] The invention belongs to the field of cigarette detection, and more particularly relates to a method and a device for visual detection of the three-dimensional appearance of a cigarette pack. Background technique [0002] The current visual inspection device for the appearance of a cigarette pack uses a camera to capture a two-dimensional image, and processes the obtained two-dimensional image to obtain two-dimensional detection and measurement results. However, in practical applications, the relative position change of the cigarette pack relative to the camera changes in three-dimensional space. The influence of the relative position change of the cigarette pack and the camera on the detection and measurement accuracy cannot be ignored. A two-dimensional tool with a large projection measurement error is used to measure a It is difficult to meet the requirements of millimeter-level precision measurement for three-dimensional swinging cigarette pack det...
