Time-to-contact estimation device and method for estimating time to contact |
摘要 |
A time-to-contact estimation device for estimating a time to contact of a moving body to an object in surroundings of the moving body, includes: an image sensor provided on the moving body, and continuously capturing time-varying images of the surroundings of the moving body; a brightness change calculation unit calculating brightness changes in pixels between the time-varying images captured one after another; and a time-to-contact calculation unit calculating optimized brightness gradients based on the brightness changes calculated by the brightness change calculation unit, and calculating the time to contact of the moving body to the object based on the optimized brightness gradients.
