Description

The present invention relates to, for example, a video information collecting device, and particularly relates to a video information collecting device capable of collecting video information of an article in a form most suitable for the purpose of use.

Conventionally, when performing a visual inspection of an article, an inspector has made use of many years of experience to perform a visual inspection. In recent years, in order to automate inspections, articles are often photographed with a photographing device and inspected by images. However, it is often difficult to identify the defective part of the article just by taking the image of the article as it is, and lighting is important so that the inspection part and the defective part of the article can be easily identified / determined. Similarly, it is important to set the position and angle of the inspection object so that the inspection location and the defect location can be easily understood and found. In addition to inspection, when taking an advertisement photograph of an article, lighting, a shooting direction, and a shooting angle are important so that the article can be seen in the most attractive and characteristic manner.

On the other hand, at factory production and management sites, we want to record the daily finished state of products in order to grasp the state of various products, measure the dimensions of products that are difficult to judge by appearance alone, and record them. Therefore, it is necessary to take a picture method such as the optimum shooting device, lighting, installation position and angle of the target product according to each application.

Patent Document 1 (Japanese Unexamined Patent Publication No. 2015-94644) discloses an inspection technique using an image processing method as a technique for inspecting collected eggs, instead of the conventional visual inspection method. That is, it is a technical idea that diffused light is radiated to an egg to be inspected in a casing in which external light is skewed to take a picture, and the quality of the target egg is judged from the brightness distribution of the imprint pattern of the photographed image.

Compared to conventional visual inspection, it does not require experience, can prevent human error, and enables automatic inspection, but it is a video utilization technology specialized only for egg inspection and for general-purpose application. Is not mentioned.
