Generating a Three-Dimensional Object Localization Lookup Table

A process executes at an electronic system. The process identifies device characteristics of an imaging device. The imaging device has signal emitters and signal detectors. The process determines a modulation signal for controlling the signal emitters to illuminate a field of view. The process partitions the field of view into a 3-dimensional plurality of voxels. According to the modulation signal and the device characteristics, the process generates unit response signals. Each unit response signal is associated with one of the voxels, and each unit response signal represents reflection from the voxel when the voxel is filled and reflects illumination generated by one of the signal emitters according to the modulation signal. The process samples the unit response signals to form unit response vectors. Each unit response vector corresponds to one of the plurality of voxels. The process then combines the unit response vectors to form the lookup table.
