3D reconstruction of objects can be achieved using both time of flight and photometric stereo imaging using four modulated white LEDs, a SPAD camera and a mobile phone. The standard deviation for the reconstruction is 4.1 mm at a distance of 70 cm.

Light-emitting diodes enable optical wireless data transmission and advanced imaging methods such as photometric stereo-imaging. Both, wireless communications into a scene and 3D imaging of that scene is enabled in parallel using the same set of LEDs

Among the many techniques developed for 3D imaging, photometric stereo-imaging excels through the simplicity of the hardware required. It can be used stand-alone or in fusion with other 3D imaging techniques for applications such as 3D scanners, face

3D images of moving objects can be achieved with a surveillance camera and four white light-emitting diodes. With these simple components, an imaging rate of 15 Hz is possible, limited by the camera framerate.

A common surveillance problem is the automatic detection of objects concealed under clothing and the identification of those carrying them. As many 2D methods rely on texture information, the application of patterned clothing can be used to camouflag
