1. A vehicle collision prevention system, the system comprising:
a first light source positioned on a left side of a vehicle and configured to emit first rays;
a second light source positioned on a right side of the vehicle and configured to emit second rays;
a camera positioned at a center of the vehicle and configured to capture a shape of the first and second rays irradiated on an object, and output the captured shape as image data;
an image processing device configured to generate braking information based on the image data; and
a braking device configured to perform, based on the braking information, decreasing speed of the vehicle or stopping the vehicle,
wherein:
the first and second rays are emitted to overlap with each other at one focal point,
a first shape of the first rays irradiated on the object is different from a second shape of the second rays irradiated on the object,
the image processing device is configured to generate the braking information when the image data indicates that the first and second rays overlap with each other on the object,
the image processing device is further configured to generate the braking information when the image data indicates that the first rays are displayed on a left side of the object and the second rays are displayed on a right side of the object, and
the image processing device is further configured not to generate the braking information when the image data indicates that the first rays are displayed on a right side of the object and the second rays are displayed on a left side of the object.
