Processing of an image representative of an observation zone

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.

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.
