BigFoot: A Mobile Solution toward Foot Parameters Extraction

The ill-fitting shoes can cause many health implications, ranging from feet ache to feet sore, from back injury to back pain and so on. Due to the manufacturing variance and design consideration, shoes from different brands will vary in size and shape. Good-fit insoles and shoes are necessary to prevent users from ill-fitting problems. Hence, we propose a novel technique that can be used to calculate parameters of the foot from smartphone RGB camera inputs. Typically, we focus on estimating six main parameters of the foot, including foot length, foot width, foot back height, toe height, heel circumference and foot circumference. These six parameters will significantly help users to find the right shoes or order a tailor-made insoles that fits their foot condition so that they can sustain their foot health and avoid further damage. Therefore, we applied different mathematical formulas accordingly and designed algorithms to estimate foot parameters.
