Abstract
An automated aiming assistance towards a shooting target for a visually- challenged or blind person is provided. The method comprises: providing the shooting weapon used by the person with a camera placed on the weapon for filming the target to be aimed at; identifying the target by shape recognition in the images shot by the camera; and transmitting a signal received by the person for guiding the person for orienting the shooting weapon towards the target.
Claims12
A method to assist a visually challenged or blind person with aiming at a shooting target, comprising:
- providing the shooting weapon to be used by the person with a camera placed on the weapon to capture images of the target to be aimed at,
- identifying the target by shape recognition in the images captured by the camera, emitting a signal to be perceived by the person to guide the person in orienting the shooting weapon towards the target
- wherein the target displays at least one shape which forms a circle, disk, or ring, and wherein the shape recognition comprises a Hough transformation to identify said shape in the captured images.
A system to assist a visually challenged or blind person with aiming at a shooting target, the system comprising:
- a camera to be placed on a weapon to be used by the person, to capture images of a target,
- a device connected to the camera, for identifying the target by shape recognition in images captured by the camera, and
- a means connected to the module for emitting a signal to be perceived by the person to guide the person in orienting the shooting weapon towards the target.
A device of a system to assist a visually challenged or blind person with aiming at a shooting target, comprising:
- a memory for storing the selected shape characteristics of a target model,
- an input for receiving current image data from a camera, and
- a processor for
- searching the current image data for shape characteristics that are homologous to the model characteristics, and
- if characteristics identical to the model characteristics are identified in the current image data, within a certain tolerance:
- deciding that the target is recognized in the current image,
- determining a distance between the target and a center of aim of the camera,
- and an output for delivering a signal for which at least one parameter is a function of said distance.
