基于图像传感器的皮肤纹理自动测量系统设计

为了客观定量评价皮肤纹理的老化，介绍了一种基于图像传感器的皮肤纹理自动测量系统。首先，利用CMOS图像传感器在光照条件下通过光电转换实现对皮肤图像的采集。然后，借助图像处理技术对采集的图像进行处理。最后，用软件定量计算皮肤表面纹理中的各测量指标（如，皮嵴的平均面积、数量、皮沟的深度等），并在此基础上通过统计学方法来分析各个测量指标的特点。整个系统集采集、处理与计算于一体，具有低功耗、高稳定、应用性广、操作简单等优点。

Design of automatic measurement system of skin texture based on image sensor

In order to evaluate aging of skin texture objectively, a kind of automatic measuring system based on image sensor is introduced. Firstly, under the condition of light, skin images collection is realized by CMOS image sensor through the photoelectric conversion. Then, the collected images are processed by using image processing technology. Finally, each measurement index, such as mean areas and number of skin ridges, depth of skin channel, and so on are calculated quantitatively with software, and with the help of statistics methods, characteristics of each measurement index are analyzed. The whole system integrates acquisition and processing with calculation, which has advantages such as low power consumption, high stability, wide applicability, simple operation, etc.
