Embodiment Construction

[0055] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0056] In the embodiment of the present invention, the specific construction scheme of the machine vision-based positioning algorithm for the inner layer box opening of the double-layer box is to arrange a fixed camera on the production line along the moving direction of the box body of the line and the vertical direction thereof to aim at the tank. Take pictures near the material opening to obtain images near the inner box opening in these two mutually orthogonal directions, and obtain the center position of the box opening in each direction through the image information to realize the positioning of the box opening. When using the image information in two mutually orthogonal directions to obtain the center position of the box opening in each direction, such as figure 1 As shown, the working process of the positioning algorithm for the inner layer of ...

Abstract

The invention discloses a double-layer box inner-layer box opening positioning algorithm based on machine vision, and belongs to the field of machine vision. The double-layer box inner-layer box opening positioning algorithm method is characterized in that: a camera is arranged in each of two mutually orthogonal directions of a production line for photographing images near an inner-layer box opening; the center of the box opening in the direction is positioned by utilizing information of each image; and finally, positioning of the whole box opening is realized by utilizing the center positionsrespectively determined by the two images. According to the double-layer box inner-layer box opening positioning algorithm method, the inner-layer box opening in the double-layer box can be accurately segmented, the center of the inner-layer box opening can be accurately positioned, and the problems that the inner-layer box opening is low in positioning precision and difficult to position are solved.

Description

technical field [0001] The invention belongs to the field of machine vision, and in particular relates to a machine vision-based algorithm for positioning an inner box opening of a double-layer box. Background technique [0002] In chemical production, there is a process of packing flammable and explosive powders into double-layer boxes. The outer layer of the double-layer box is a wooden packing box, and the inner layer is an iron medicine charging box. Since there is a gap of 10mm to 15mm between the two boxes, the filling process powder is easily thrown into the gap, resulting in serious safety hazards. Hidden danger. Now its specific filling process is as follows: the double-layer box body is manually placed at the starting point of the conveying track. The double-layer box reaches the position near the filling port along the conveying track, and the filling is started by triggering the limit switch: stop the operation of the conveying track and start the jacking devic...
