Abstract

The present invention relates to a method for sending information to an individual ( 11 ) located in the environment of a vehicle ( 10 ), the method comprising the following steps: acquiring an image of the environment of the vehicle ( 10 ), detecting, where applicable, at least one individual ( 11 ) on the acquired image, determining a probability of collision between the individual ( 11 ) detected on the acquired image and the vehicle ( 10 ), sending at least one item of information to the detected individual ( 11 ), the information sent depending on the determined probability of collision, the steps of detecting, determining and sending being repeated, for the same individual ( 11 ), with subsequent acquired images as long as said individual ( 11 ) is detected on said images and as long as the probability of collision is greater than a threshold.

Claims (19)

1. A method for sending information to at least one individual located in the environment of a vehicle, the method being implemented by an information sending system associated with the vehicle, the information sending system comprising an acquisition unit, a computer and an information sending unit, the method comprising steps:

acquiring at least one image of the environment of the vehicle, by the acquisition unit,

detecting, where applicable, at least one individual on the acquired image, by the computer,

determining a probability of collision between the individual detected on the acquired image and the vehicle, by the computer,

sending at least one item of information in the direction of the individual detected on the acquired image, by the information sending unit, the information being sent depending on the determined probability of collision,

wherein the steps of detecting, determining and sending are repeated, for the same individual, with subsequent acquired images, as long as said individual is detected on said images and the probability of collision is greater than a threshold, and

wherein the steps of detecting, determining and sending, as well as repeating said steps are performed for a predetermined number of individuals detected on the acquired image.

2. The method according to claim 1 , wherein the method comprises, where applicable, a step of identifying, by the computer, on the acquired image, a face and/or of a direction of gaze of the detected individual the item of information sent during the sending step being in the direction of the detected face and/or of the direction of gaze of the individual detected on the acquired image.

3. The method according to claim 2 , wherein the probability of collision is determined depending on the gaze direction of the individual detected on the acquired image.

4. The method according to claim 3 , wherein the probability of collision is in addition determined depending on a calculated distance between the detected individual and the vehicle.

5. The method according to claim 2 , wherein the method comprises a step of memorizing, by the computer, features of the face and/or the gaze direction of the individual detected on the acquired image, when the features of the face memorized for said image and features of a face memorized for previous images correspond to the same individual, the probability of collision is determined depending on the acquired image and of said previous images, the previous images being consecutive images and acquired immediately before said image.

6. The method according to claim 1 , wherein the probability of collision is determined depending on the position of the individual detected in the acquired image.

7. The method according to claim 2 , wherein the item of information is visual information modeling the eyes and mouth of a virtual driver of the vehicle, the modeled eyes being oriented in the direction of gaze of the individual detected on the acquired image, the curvature of the modeled mouth depending on the determined probability of collision.

8. The method according to claim 1 , wherein the item of information is visual, auditory, vibratory, radio, olfactory and/or tactile information.

9. A vehicle, configured to implement a method for sending according to claim 1 , the vehicle being associated with an information sending system comprising an acquisition unit, a computer and an information sending unit.

10. The vehicle according to claim 9 , wherein the information sending unit is located outside the vehicle.

11. The vehicle according to claim 9 , wherein the vehicle is an autonomous vehicle.

12. The vehicle according to claim 9 , wherein the vehicle is a rail vehicle.

13. The method according to claim 1 , wherein at least the acquiring step, the detecting step, the determining step, and the sending step are performed at each moment.
