Abstract: A contactless tire inspection apparatus for tire tread depth measurement using 3D reconstruction includes a driver side (DS) measurement device (MD) and a passenger side (PS) MD. The DS MD includes a DS light source configured to, responsive to receiving a trigger signal (TS), project a first structured illumination (SI) onto a DS tire of a vehicle and at least one DS camera configured to, responsive to receiving the TS, capture DS image(s) of the first SI projected onto the DS tire for 3D reconstruction. The PS MD includes a PS light source configured to, responsive to receiving the TS, project a second SI onto a PS tire of the vehicle and at least one PS camera configured to, responsive to receiving the TS, capture PS image(s) of the second SI projected onto the PS tire for 3D reconstruction when the at least one DS camera captures DS image(s).
