The high cost of state-of-the-art equipment in the health field makes it unfeasible to apply this technique in the clinics\u2019 routines. In this vein, RGB-D and RGB equipment, which have joint tracking tools, are tested with portable and low-cost solutions to enable computational motion analysis. The recent release of Google MediaPipe, a joint inference tracking technique that uses conventional RGB cameras, can be considered a milestone due to its ability to estimate depth coordinates in planar images. In light of this, this work aims to evaluate the measurement of angular variation from RGB-D and RGB sensor data against the Qualisys Tracking Manager gold standard. A total of 60 recordings were performed for each upper and lower limb movement in two different position configurations concerning the sensors. Google\u2019s MediaPipe usage obtained close results compared to Kinect V2 sensor in the inherent aspects of absolute error, RMS, and correlation to the gold standard, presenting lower dispersion values and error metrics, which is more positive. In the comparison with equipment commonly used in physical evaluations, MediaPipe had an error within the error range of short- and long-arm goniometers.<\/jats:p>","DOI":"10.3390\/s23010003","type":"journal-article","created":{"date-parts":[[2022,12,20]],"date-time":"2022-12-20T03:29:20Z","timestamp":1671506960000},"page":"3","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":45,"title":["Validation of Angle Estimation Based on Body Tracking Data from RGB-D and RGB Cameras for Biomechanical Assessment"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3348-5142","authenticated-orcid":false,"given":"Thiago Buarque de Gusm\u00e3o","family":"Lafayette","sequence":"first","affiliation":[{"name":"Departamento de Engenharia Biom\u00e9dica, Universidade Federal de Pernambuco (UFPE), Recife 50670-901, Brazil"},{"name":"Voxar Labs, Universidade Federal de Pernambuco (UFPE), Recife 50670-901, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Victor Hugo de Lima","family":"Kunst","sequence":"additional","affiliation":[{"name":"Voxar Labs, Universidade Federal de Pernambuco (UFPE), Recife 50670-901, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pedro Vanderlei de Sousa","family":"Melo","sequence":"additional","affiliation":[{"name":"Departamento de Fisiotarapia, Universidade Federal de Pernambuco (UFPE), Recife 50670-901, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paulo de Oliveira","family":"Guedes","sequence":"additional","affiliation":[{"name":"Voxar Labs, Universidade Federal de Pernambuco (UFPE), Recife 50670-901, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7180-512X","authenticated-orcid":false,"given":"Jo\u00e3o Marcelo Xavier Nat\u00e1rio","family":"Teixeira","sequence":"additional","affiliation":[{"name":"Voxar Labs, Universidade Federal de Pernambuco (UFPE), Recife 50670-901, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C\u00ednthia Rodrigues de","family":"Vasconcelos","sequence":"additional","affiliation":[{"name":"Departamento de Fisiotarapia, Universidade Federal de Pernambuco (UFPE), Recife 50670-901, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Veronica","family":"Teichrieb","sequence":"additional","affiliation":[{"name":"Voxar Labs, Universidade Federal de Pernambuco (UFPE), Recife 50670-901, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alana Elza Fontes","family":"da Gama","sequence":"additional","affiliation":[{"name":"Departamento de Engenharia Biom\u00e9dica, Universidade Federal de Pernambuco (UFPE), Recife 50670-901, Brazil"},{"name":"Voxar Labs, Universidade Federal de Pernambuco (UFPE), Recife 50670-901, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1186\/1743-0003-3-4","article-title":"Gait analysis methods in rehabilitation","volume":"3","author":"Baker","year":"2006","journal-title":"J.
