Obtaining accurate estimates of the volume of stacked wood is important in view of the increasing value of wood as raw material. Therefore, the forest companies have become increasingly concerned about the methods currently used to convert cubic meters for stereo. In this context, emerged the need of optimizing the measurement process and accuracy of the volume of stacked wood. For this, companies have been testing methods with greater efficiency, speed and low operating cost. Existing methods made through approximate equations, and also by determining the conversion factor, called the stacking factor (Fe), are questioned, due to errors and inaccuracies. The use of digital photographs is an alternative method that would minimize operator intervention, allowing greater control and speed the process, thus eliminating part of the imprecision of the traditional method. The use of the method is viable, due to present an error of about 10% while traditional methods showed an error of 17%
