System and method for the measurement of the relative position of an object with respect to a point of reference

SCHEDA BREVETTO

Abstract:

A method and a system for measurement of the relative position of an object with respect to a point of reference which includes acquiring a plurality of images, each of said images being adapted to display the point of reference, processing each image of the plurality of acquired images, the step of processing each image further including the step of recognizing the object inside each of the images performed by a classifier and training with examples adapted to the construction of the classifier, and computing the relative position of the object with respect to the point of reference.

Advantages:

Hence, a field of play comprising such system could advantageously be provided.
The main advantage of the method and of the system according to the present invention lies in that those entail no modification to any component of the field of play, or to the ball. A second advantage lies in the robustness and in the reliability of the detection of the scored goal event.
A third advantage lies in the completeness of the information on the position of the object with respect to a point of reference, as the method provides the threedimensional coordinates thereof. A fourth advantage lies in that the system according to the present invention uses, for image acquisition, high-speed digital cameras, whose performances surpass those of the common cameras as well as those of the human eye.
To solve this problem, several known systems, all referable to the same category, provide the use of sensors, inserted inside of the goal structure, receiving a signal from transmitters applied into the playing ball when the latter crosses the goal mouth.
Purpose of the present invention is to solve the abovecited problems of the known art providing a method for the measurement of the relative position of an object with respect to a point of reference, characterized in that it comprises the following steps: – acquiring a plurality of images, each of said images being apt to display said point of reference; – processing each image of said plurality of acquired images; and – computing said relative position of said object with respect to said point of reference.

Application field:

APPARATUS FOR PHYSICAL TRAINING, GYMNASTICS, SWIMMING, CLIMBING, OR FENCING; BALL GAMES;

COMPUTING; CALCULATING; COUNTING score computers for games;

Technical board:

The present invention further provides a system for the measurement of the relative position of an object with respect to a point of reference, comprising: – one or more image acquisition subsystems; and – an unit for the processing of said acquired images.
In this case the system 1 provides redundant information, however the redundancy enhances the reliability of the measurement of the scored goal event..
