Character detection of edible oil bottles

Recently, our company received a consultation from a well-known domestic edible oil production enterprise on how to solve the detection problem of production character information on the bottle body. The customer reported that due to the plastic material of the edible oil bottle and the position of the printed characters, it has curved surfaces and arcs. Previously, the customer consulted many visual light source manufacturers, but none of them could effectively solve the problems of light emission and glare, resulting in a low recognition rate.

Please refer to the following picture for the effect of the primary lighting method: The reflection is quite severe and it is impossible to recognize the characters at all.

Under normal circumstances, the improvement effect of lighting: The contrast in the following picture has been greatly improved compared to before. Although there is still a little reflection, the position does not affect the part of the characters we detect. However, there are still a few characters that may be misjudged or not read out (for example, the character LL after the United States is prone to be misjudged as 11).

The solution effect drawing provided by Shanghai K-WELL: From the picture, each letter can be clearly distinguished, and the contrast is very high. There is no obvious reflection within the detection character range, and the stability is very high.
