The therapeutic elastic gloves are of great help in the treatment of hand burns and scalds, making superficial and mild burns heal quickly without residual scars or damage to a patient’s functional ability. However, the hand data used to create the elastic gloves for burns and scalds are usually measured by workers. This manual measurement method has a high cost, large error, and unreliable results. In this paper, we propose an image-based parameter measurement method and establish a portable measuring system for finger and palm parameters; these parameters are then applied to create therapeutic gloves for burn and scald treatments. The proposed method can provide an accurate and rapid measurement of the finger and palm parameters. The experimental results for normal hand parameters and injured hand parameters show the effectiveness of the proposed method.
