A sunscreen detector, detection device and method

Abstract

The present application relates to a sunscreen detector, a detection device and a method. The detection device obtains a first differential image corresponding to the specific chemical through the reference light signal in the reference optical band corresponding to the specific chemical and through the reference light source and the image acquisition device, and is used to determine that the specific chemical is in the specified chemical The thickness distribution on the area, so as to realize the combination of optical measurement technology and image processing technology to provide a general and reliable detection method for various medical preparations, cosmetics or other chemicals suitable for the human body to judge the smearing of chemicals. It extends to the design advantages of smart terminal equipment and household daily necessities, and can effectively combat interference caused by external environmental factors.

Description

technical field [0001] The present application relates to the field of Internet technologies, in particular to the field of image processing technologies, and in particular, to a sunscreen detector, a detection device, and a method. Background technique [0002] With the development of Internet technology and image processing technology, the use of optical measurement technology for non-destructive or non-contact measurement and the use of image processing technology to extract useful information have been widely used in many aspects, and the use of the Internet has also appeared. An application that combines the terminal detection capability with the storage capability or computing capability of the cloud. These products or services, which combine optical measurement technology and image processing technology, can be used as accessories or integrated into smart terminal devices such as mobile phones and wristbands, or household daily necessities such as beauty mirrors or va...

Problems solved by technology

If the application is uneven, such as over application in some places, under application in some places or even no application, the desired effect will not be achieved

In addition, these chemicals or chemical products suitable for the human body are generally not suitable for long-term maintenance on the surface of the human body, but need to be removed or cleaned after a certain period of time, and the residue on the human body surface may cause problems such as pore blockage

[0003] In the prior art, there is a lack of a general-purpose detection method that can combine optical measurement technology and image processing technology to provide real-time and reliable judgments for the actual application of the above-mentioned various medical preparations, cosmetics, or other chemicals suitable for the human body

Moreover, products or services in the prior art require customized optical devices such as light sources and light sensors, which not only occupy additional volume but also increase manufacturing costs, making it difficult to conveniently extend to smart terminal devices such as smartphones
