Detection system based on line scanning camera

The utility model 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 synchronou
