A method for corrected depth measurement with a time-of-flight camera using amplitude-modulated continuous light. In order to enable an accurate and efficient depth measurement with a time-of-flight camera, the method includes, for each of a plurality of pixels of a sensor array of the camera: acquiring with the camera a raw depth value rfor the pixel; and automatically calculating a ground truth value raccording to: r=g(r&#x2212;c)+c, to correct a systematic depth error of the raw depth value r, wherein cis a pixel-dependent first offset, g is a pixel-independent first function and cis a pixel-independent second offset.

A transmitter electrode () for a capacitive sensing device comprises a conductive sheet material (), said conductive sheet material comprising a first connecting point () for connecting the electrode to an electronic sensing unit. According to the invention the conductive sheet material comprises at least one second connecting point for connecting the electrode to an electronic sensing unit, said second connecting point (') being arranged at a certain distance from said first connecting point so that said conductive sheet material forms a conductive path between said first and second connecting point. The first and second connecting point (&#x2032;), which in use are both connected to the electronic sensing unit, enable to check the integrity of the transmitter electrode and the connection lines used to connect the transmitter electrode to the electronic sensing unit.
