There is a quite wide range of animal leathers such as cow leather, sheep leather and buffalo leather used for leather garments and leather goods such as bags, wallets and other customized leather articles. The drawbacks of manual cutting can be eliminated by laser-based cutting. However, unwanted carbonization is happened owing to the higher thermal influence. There is no standard procedure or method available to measure the carbonization region on leather cutting. Diode lasers can process leather rapidly and efficiently. In the present work, an attempt was proposed to introduce the image processing-based measurement approach in leather cutting using CO₂ laser and diode laser. The cutting experiments were performed on sheep leather with a thickness of 1 mm. It was found that the proposed can effectively measure the heat-affected zone (HAZ) of leather cutting. It has also been found that diode laser could produce lower HAZ than CO₂ laser on leather cutting.

用于皮革服装和皮革制品如包、钱包和其他定制皮革制品的牛皮革、羊皮革和水牛皮等动物皮革种类繁多。手动切割的缺点可以通过基于激光的切割来消除。然而，由于较高的热影响，会发生不需要的碳化。没有可用于测量皮革切割碳化区域的标准程序或方法。二极管激光器可以快速高效地加工皮革。在目前的工作中，建议尝试在使用 CO _{2 的}皮革切割中引入基于图像处理的测量方法激光器和二极管激光器。切割实验在厚度为 1 毫米的羊皮上进行。结果表明，该方法可以有效地测量皮革切割的热影响区（HAZ）。还发现在皮革切割时，二极管激光可以产生比 CO ₂激光更低的 HAZ 。
