Abstract

The invention discloses a visual detection device comprising a sample placing surface, a reflection block and a camera that are sequentially arranged along a straight line. The reflection block includes a plurality of reflection surfaces that are sequentially connected to form a through hole penetrating the reflection block; the cross section of the through hole is gradually reduced in a directionfrom the camera to the placing surface. In addition, a visual detection method comprises the following steps: step a, adjusting a distance between a sample and each of a plurality of inclined reflecting surfaces; step b, collecting mirror images of a sample in a polygon mirror by using optical imaging equipment; step c, extracting and splicing mirror images in the reflection block by using an image processing program; and step d, carrying out defect analysis and marking on the images acquired in batches by using the image processing program. According to the invention, multi-surface images ofthe product are simultaneously collected by combining one camera with the polygonal mirror, so that the hardware cost and the acquisition time are reduced substantially by being compared with the mode of simultaneous detection by using a plurality of CCD cameras; and the visual detection device and visual detection method are applied to the technical field of detection equipment.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a visual detection device and a visual detection method. Background technique [0002] At present, the mainstream multi-faceted appearance inspection of products uses three or four CCD cameras to take pictures from the side for inspection. Such an inspection system is very complicated in structure, and the cost is also very expensive. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a visual detection device and a visual detection method to solve one or more technical problems in the prior art, and at least provide a beneficial option or create conditions. [0004] The solution that the present invention solves its technical problem is: [0005] A visual detection device, comprising a sample placement surface, a reflective block and a camera, the placement plane, the reflective block and the camera are seq...
