Claim 3:
4. A distributed three-dimensional (3D) induced polarization (IP) data acquisition and processing method, comprising: acquiring a current signal of a region to be measured, the current signal being a preset current signal transmitted by a transmitter module to a ground where the region to be measured is located; acquiring a voltage signal and an apparent polarizability of the region to be measured, the voltage signal being a voltage signal acquired by each of receiver modules for the ground where the region to be measured is located; and respectively processing the current signal and the voltage signal to obtain an apparent resistivity of the region to be measured; wherein the receiver modules each comprise a voltage recorder and at least three receiving electrodes, the receiving electrodes each are connected to the ground, and configured to acquire a voltage signal flowing through the ground; and the voltage recorder is connected to each of the receiving electrodes, and configured to acquire the voltage signal and the apparent polarizability of the ground where the region to be measured is located, and record the voltage signal and the apparent polarizability, and wherein when there are three receiving electrodes, the three receiving electrodes are arranged in an L-shaped distribution.
