Abstract
The present disclosure provides a method for calculating a TTC for an object and a vehicle for a calculation device, including: generating a timestamp matrix in accordance with a series of event data from a DVS coupled to the vehicle; scanning events in the timestamp matrix in a predetermined scanning direction, so as to calculate a time gradient of each event in the predetermined scanning direction; creating at least one subset consisting of a first quantity of consecutive events in the predetermined scanning direction and each with a positive time gradient; calculating a spatial position of each event in each subset in accordance with intrinsic and extrinsic parameter matrices of the DVS; and calculating the TTC in accordance with the spatial position and the timestamp of each event in the subset. The present disclosure further provides the calculation device and a corresponding vehicle.
