Abstract
The invention discloses a detection system based on a line scanning camera. The detection system comprises the line scanning camera and a conveyer belt which is used for conveying products, wherein reflectors are respectively arranged at the left side and the right side of the conveyer belt; an included angle between each of the left and right reflectors and the conveyer belt is 45 degrees; and the line scanning camera is positioned right above the center of a scanning area between the left and right reflectors. Meanwhile, a side light source or a front light source is arranged above the left side and the right side of the scanning area respectively; and a front light source or a side light source is arranged above the front side and the rear side of the scanning area respectively. According to the detection system, the multi-channel imaging of the camera is achieved by the two added reflectors; based on the reflection characteristic of the reflectors, one front image and two side images can be synchronously formed by the reflector camera; and in the imaging manner, cameras are reduced, the cost is saved and the debugging difficulty is reduced.
Description
Technical field
The present invention relates to a kind of system that product is detected, be specifically related to a kind of detection system based on line scan camera.
Background technology
Existing product detects (detecting positive, side) simultaneously, and what adopt is multicamera system, and system cost is high like this, and debugging difficulty is large, is difficult to adapt to existing customer's demand.
Summary of the invention
The object of the invention is to detect for existing product the problem and shortage that multicamera system exists, a kind of detection system based on line scan camera is provided.
Technical scheme: a kind of detection system based on line scan camera, comprise line scan camera and for transporting the conveying belt of product, the left and right sides at conveying belt is respectively arranged with reflective mirror, left and right sides reflective mirror and conveying belt angle are 45 degree, and line scan camera is directly over the center, scanning area between the reflective mirror of the left and right sides (conveying belt center).
Above the left and right sides, scanning area, be respectively arranged with side light source or front light source, above both sides, front and back, scanning area, be respectively arranged with front light source or side light source.
Beneficial effect: the present invention is the multi channel imaging of realizing camera by increasing by 2 reflective mirrors, according to the characteristic-reflection of reflective mirror, can become width front and 2 secondary side images by catoptron camera simultaneously, such imaging mode has reduced camera, save cost, reduced the difficulty of debugging.
Brief description of the drawings
Fig. 1 is the end face structure schematic diagram of detection system of the present invention;
Fig. 2 is the side structure schematic diagram of detection system of the present invention;
Fig. 3 is the plan structure schematic diagram of detection system of the present invention.
Embodiment
Fig. 1, Fig. 2 and Fig. 3 are three schematic diagram that the present invention is based on the detection system of line scan camera.In figure, label 1 is line scan camera, and 2 is side light source, and 3 is front light source, and 4 is reflective mirror, and 5 is conveying belt, and 6 is product.Certain section of region of conveying belt is as the scanning area that product is detected, directly over the center of this scanning area, be provided with line scan camera 1, and above the left and right sides, scanning area, be respectively arranged with side light source 2 (or front light source), above both sides, front and back, scanning area, be respectively arranged with front light source 2 (or side light source).Meanwhile, be respectively arranged with reflective mirror 4 in the left and right sides of the conveying belt 5 of scanning area, left and right sides reflective mirror 4 is 45 degree with the angle of conveying belt 5, line scan camera 1 directly over the center, scanning area between left and right sides reflective mirror 4,
The present embodiment one camera detection system realizes the detection of front, side simultaneously equally, and this mode greatly reduces the difficulty of cost and debugging.
