Patent Images
1. A method for processing data, in particular an image representative of an observation zone in which is situated an object arranged with respect to a reference plane, comprising the following steps:
- reception of said image which has been captured beforehand by means of first and second image capture devices,display of said image received,said method comprising the following steps;
in the course of the display step, display of said image in a plane which comprises an object plane, containing said object, and said reference plane which has been determined beforehand as being the plane situated at the intersection of a conical beam and of a parallel beam emitted respectively by said first and second image capture devices,determination, in the displayed image, of the number of pixels separating two contiguous sides, respectively of the object plane and of the reference plane, and extending along a determined direction (X or Y),correlation of the determined number of pixels with the value of the measurement of the real distance which separates said object from said reference plane.

Abstract
A method for processing data, in particular an image representative of an observation zone in which is situated an object arranged with respect to a reference plane.
Such a method comprises the following steps:
- reception of the image which has been captured beforehand by means of first and second image capture devices,
- display (EV2) of the image received in a plane which comprises an object plane, containing said object, and said reference plane which has been determined beforehand as being the plane situated at the intersection of a conical beam and of a parallel beam emitted respectively by said first and second image capture devices,
- determination (EV3), in the displayed image, of the number of pixels separating two contiguous sides, respectively of the object plane and of the reference plane, and extending along a determined direction (X or Y),
- correlation (EV4) of the determined number of pixels with the value of the measurement of the real distance (d) which separates said object from said reference plane.

7. A device for processing data, in particular an image representative of an observation zone in which is situated an object arranged with respect to a reference plane, the device comprising:
-
means for receiving said image which has been captured beforehand by means of first and second image capture devices, means for displaying said image received, said display means are designed to display said image in a plane which comprises an object plane, containing said object, and said reference plane which has been determined beforehand as being the plane situated at the intersection of a conical beam and of a parallel beam emitted respectively by said first and second image capture devices, means for determining in the displayed image the number of pixels separating two contiguous sides, respectively of the object plane and of the reference plane, and extending along a determined direction (X or Y), means for correlating the determined number of pixels with the value of the measurement of the real distance which separates said object from said reference plane. - View Dependent Claims (8, 9, 10, 11, 12)

13. A system for measuring a real distance between at least one object and a reference plane, comprising first and second image capture devices for capturing an observation zone in which is situated said object with respect to the reference plane, said system comprising:
-
means for determining said reference plane as being the plane situated at the intersection of a conical beam and of a parallel beam emitted respectively by the first and second image capture devices, a device for processing data comprising; means for receiving an image of said captured observation zone, means for displaying said image received in a plane which comprises an object plane, containing said object, and said reference plane, means for determining in the displayed image the number of pixels separating two contiguous sides, respectively of the object plane and of the reference plane, and extending along a determined direction (X or Y), means for correlating the determined number of pixels with the value of the measurement of the real distance (d) which separates said object from said reference plane. - View Dependent Claims (14)
