Abstract
In some implementations, there is provided a method. The method may include receiving data characterizing a plurality of digital video frames; detecting a plurality of features in each of the plurality of digital video frames; determining, from the detected features, a local scale change and a translational motion of one or more groups of features between at least a pair of the plurality of digital video frames; and calculating a likelihood of collision. Related apparatus, systems, techniques, and articles are also described.

A method comprising:
- receiving data characterizing a plurality of digital video frames;
- detecting a plurality of features in each of the plurality of digital video frames;
- determining, from the detected features, a local scale change and a translational motion of one or more groups of features between at least a pair of the plurality of digital video frames;
- and
- calculating a likelihood of collision.
A non-transitory computer readable storage medium comprising executable instructions which when executed by at least one processor provides operations comprising:
- receiving data characterizing a plurality of digital video frames;
- detecting a plurality of features in each of the plurality of digital video frames;
- determining, from the detected features, a local scale change and a translational motion of one or more groups of features between at least a pair of the plurality of digital video frames;
- and
- calculating a likelihood of collision.
The non-transitory computer readable storage medium of claim 9, further comprising:
- classifying one or more groups of features as being on a collision trajectory by comparing a collision point with a predetermined value defining a safety envelope around a camera.
A system comprising:
- at least one processor circuitry;
- at least one memory storing instructions which, when executed by the at least one processor circuitry, causes operations comprising:
- receiving data characterizing a plurality of digital video frames;
- detecting a plurality of features in each of the plurality of digital video frames;
- determining, from the detected features, a local scale change and a translational motion of one or more groups of features between at least a pair of the plurality of digital video frames;
- and
- calculating a likelihood of collision.
