It has previously been demonstrated that detectors can be constructed that are sensitive to the 3D trajectory of a structure. The general approach is based upon a biological model for looming detectors proposed by K. Beverley and D. Regan (J. Physiol., vol.193, p.17-29, 1973). The computational model is based upon recent results in motion analysis and static stereopsis concerning the measurement of trajectory without prior form recognition. Some of the characteristics of these detectors are examined, and a number of experiments that show the responses of particular detectors to structure with different trajectories, disparities, and velocities are described. Some of the similarities and differences between the detectors presented and models for looming detectors present in biological vision systems are indicated
