System and method for identifying a product

A method for identifying a product on a shelf, the method comprising:

• providing a database which comprises a list of plurality of products, and—for each one of the products of the list—a first value of the at least one parameter of emitted light and a second value of the at least one parameter of modified light, based on an experimental trial in which first emitted light having the first value of the at least one parameter has interacted with the product of the list and has yielded first modified light having the second value of the at least one parameter at a baseline ambient lighting having a baseline value of the at least one baseline parameter, and wherein a combination of the first value and of the second value is unique to the product of the list;
• detecting an ambient value of the at least one parameter of a second ambient light at a shelf;
• providing a light emitter configured to emit a second emitted light, the second emitted light having the at least one parameter with a third value;
• providing a sensor for detecting a second modified light, the second modified light being generated by interaction of the second emitted light with an unknown product, the second modified light having a fourth value of the at least one parameter;
• adjusting a sensitivity of the sensor to compensate for a difference between the first ambient light and the second ambient light, such that an ambient light detected by the sensor is about equal to the first ambient light at the shelf even the first ambient light and the second ambient light are different;
• using the light emitter to illuminate an unknown product on the shelf with the second emitted light, wherein the second value is controlled to correspond to the first value;
• detecting the second modified light via the sensor;
• processing the first value and the second value of the at least one product from the database, and the third value of the fourth value corresponding to the unknown product, to determine whether the unknown product corresponds to one of the products of the plurality of products.

A method for identifying a product on a shelf, the method comprising:

• providing a database which comprises a list of comprising at one or more products, and—for each one of the one or more products of the list—a first value of the at least one parameter of emitted light and a second value of the at least one parameter of modified light, based on an experiments trial in which first emitted light having the first value of the at least one parameter has interacted with the product of the list and has yielded first modified light having the second value of the at least one parameter at a baseline ambient lighting having a baseline value of the at least one parameter, and wherein a grouping of the first value and of the second value is unique to the product of the list;
• detecting an ambient value of the at least one parameter of a second ambient light at a shelf;
• providing a light emitter configured to emit a second emitted light, the second emitted light having the at least one parameter with a third value;
• providing a sensor for detecting a second modified light, the second modified light being generated by interaction of the second emitted light with an unknown product, the second modified light having a fourth of the at least one parameter;
• adjusting the light emitter to compensate for a difference between the first ambient light and the second ambient light, such that the third value is an adjustment of the first value in the database;
• using the light emitter to illuminate an unknown product on the shelf with the second emitted light;
• detecting the second modified light via the sensor;
• processing the first value and the second value of the one or more products of the list, and the third value and fourth value corresponding to the unknown product, to determine whether the unknown product corresponds to one of the products of the plurality of products.
