Objective： To research a low cost, non-contact and high efficiency technology for wound image acquisition and area calculation based on non-contact wound area image measurement technology of advanced RISC machines（ARM）, so that achieve quick, accurate and convenient measurement for wound area. Methods： Proposed a measurement method for wound area based on ARM9 embedded platform; used the embedded pictures to realize the low cost and high efficiency for the image acquisition, and used the calibration technology of the laser beam area to realize the collection for non-contact wound area. Results： The comparison results between the old method and the new method showed that all of measuring errors were in 1%, but the design of the new technology has the advantages of non-contact. Conclusion： By using the new method, the wound area can be rapid, accurate, convenient measured, at the same time, it can avoid the cross infection. The method has a certain clinical application prospect.
