1. A computer implemented method for generating a collision warning, the method comprising:
- defining, by the processor, a monitoring area monitoring by a warning device attached to a first object, wherein the monitoring area moves with the warning device;
determining a change in a collision awareness factor in relation to the monitoring area, the collision awareness factor corresponding to an estimated awareness level of an operator of the first object of a likelihood of collision with a second object, wherein determining the collision awareness factor is based on a direction of movement of the first object, a velocity of the first object, an angular divergence of a focus direction relative to a movement direction of the first object, a number and a distribution of one or more objects within the monitoring area, a velocity of one or more objects within the monitoring area, a size and a shape of one or more objects within the monitoring area, a position and a proximity of one or more objects within the monitoring area, a current weather condition in the monitoring area, a light condition in the monitoring area, a time of day and a level of humidity in the environment of the first object;
defining a warning zone in relation to the monitoring area based on the collision awareness factor; and
generating a warning based on at least the second object being within the warning zone, and the collision awareness factor.

Abstract
A monitoring area may be defined for a monitoring device attached to a first object, wherein the monitoring area moves with the monitoring device. The monitoring device may detect a second object in the monitoring area. A collision awareness factor may be determined in relation to the monitoring area, and a warning zone may be defined in relation to the monitoring area based on the collision awareness factor. A warning may be generated based on detecting the second object within the warning zone and based on the collision awareness factor.
