Abstract: When it comes to the development of customized orthopedic products that fit the patient’s anatomy the measurement capture method is a constant challenge. Therefore, the measuring instrument must have high accuracy. Considering this context, the three-dimensional digitization methods are helpful tools for the capture of complex measurements and geometries. The advantages and limitations of each scanning method will determine the fidelity in data capture and the dimensional singularities of the object to be scanned. This paper aims to validate and determine the precision of optical scanning tools in support of orthopedics. They were evaluated here as digitization techniques of photogrammetry and structured light for the representation of the patient’s anatomy. As result a comparative study between the dimensional deviation of the digital 3D models and the actual limb is made. The obtained results evidenced greater dimensional and geometric fidelity of the digital model generated by scanning through structured light.
