DESCRIPTION OF EXAMPLES OF EMBODIMENTS OF THE INVENTION The present description is given without limitation, each characteristic of an embodiment being able to be combined with any other characteristic of any other embodiment in an advantageous manner.

We can now note that the figures are not to scale.

FIG. 1, which is not to scale, shows a schematic view of an embodiment of the method 100 which is the subject of the present invention.

This method 4 100 for translating data, encoded by a first code graphically representing said data, into a second code, the method comprising: a step 105 of capturing an image at least partially comprising a signal representative of the data encoded by the first code, a step 110 of reading the first code in the captured image, a step 115 of determining the data encoded by the first code as a function of a decoding key of the first code, a step 120 of generating a second code graphically representing data and 113 a step 125 for encoding at least part of the data determined as a function of the second code generated.

The capture step 105 is performed, for example, by an image sensor such as a camera integrated into a smartphone or independent.

The captured image must be that of a surface on which the data encoded by the first code are printed or displayed, in the case of a screen.

The reading step 110 is carried out, for example, by software embedded in an electronic component of a preferably mobile terminal.

This software is configured to recognize, on a captured image, the presence of data encoded by a code.

This recognition is achieved, for example, by the recognition of a pattern corresponding to the usual pattern of a code among a plurality of patterns pre-recorded at the level of the reader.

This pattern corresponds, for example, to an OR-code pattern.

In variants, any other known pattern can be used.

At the end of the reading step 110, the encoded data is extracted from the images to be decoded during the determination step 115.

The determination step 115 is carried out, for example, by software embedded in an electronic component of the terminal.

This software is configured to decode, according to a decoding key, the data encoded by the first code.

The decoding key is recorded locally at the terminal 30 or accessible at the level of a remote memory of the computer server type via a point-to-point wired or wireless link or via a data network of the Internet or cellular network type.

The particular decoding method depends on the first code and is therefore not described here.

At the end of the determination step 115, the data has been decoded and the content of this data can be read in clear.

The data can form a chain of alphanumeric characters or values representative of parameters of an audiovisual file, such as an image, a video or a sound for example.

Generation step 120 is performed, for example, by computer software embedded in an electronic component of the terminal.

The generated code is selected manually or automatically from a list of codes 10 pre-recorded in a local or remote memory.

In the event of manual selection, the terminal is connected to a man-machine interface, of mouse, keyboard or touch screen type, allowing an operator to select a code from a list of codes.

In variants, the selection is derived from answers to a questionnaire 15 by the operator, the questions of this questionnaire targeting, for example: the name of the owner of the object from which the image was captured, the name of the future owner of the object, the name of the next conveyor of the object, the name of the manufacturer of the object or the name of the next geographic destination of the object.

For example, the software may have available an owner / code association list making it possible to select the second code indirectly for the operator who only enters the name of the owner.

In the event of automatic selection, the terminal communicates with a remote memory to obtain the second code automatically.

For example, the terminal communicates geographic coordinates of the GPS type (for “Global Positioning System”) and receives the second code in return.

These variants assume knowledge, at the level of the remote memory, of the succession of steps for moving the object on which the data encoded by the first code are affixed.

Thus, for example, a second code corresponds to a first stopover in a first port, then a third code corresponds to a second stopover in a second port and so on.

6 The encoding step 125 is carried out, for example, by the implementation of software embedded in an electronic component of the terminal.

This software converts at least part of the determined data into encoded data.

Thus, as will be understood, it is possible, with the method 100 which is the subject of the present invention, to convert data encoded in a two-dimensional bar code into data encoded in an OR-code for example.

In embodiments, such as that shown in FIG. 1, the method 100 comprises, during the determination step 115: a step 130 of sending a request for sending a decoding key at 10. function of the captured image and a step 135 of receiving the decoding key.

The sending step 130 is carried out, for example, by the use of an electronic circuit of the terminal configured to implement a wired or wireless link with a remote memory.

15 The link corresponds, for example, to a link of the IEEE 802.11 type, called "WiFi to a link on an IP network (for" internet protocol,), translated as internet protocol), to a link on a mobile telecommunications network of GSM (for “special mobile group”), 3G, 4G or 5G type, or to a connection on a so-called machine-to-machine network of Sigfox (registered trademark) or LoRa type.

20 Depending on the image transmitted, the remote memory identifies the type of code and returns the corresponding decoding key.

If no code is identified by the remote memory in the image, the remote memory transmits an error signal.

The reception step 135 is carried out, for example, by the use of an electronic circuit of the terminal associated with the wired or wireless link implemented during the transmission step 130.

In embodiments, such as that shown in FIG. 1, the method 100 comprises, upstream of the generation step 120, a step 140 of selecting a type of reader of the second code, the second code being generated in depending on the type of reader selected.

This selection step 140 is performed, for example, manually or automatically by software embedded in an electronic circuit of the terminal.

This selection 140 can implement a man-machine interface allowing manual selection, by entry or by selection from a predetermined list, of a type of reader.

This type of reader is associated, in local or remote memory, with a second particular code according to the reading capacities of the reader, in terms of resolution or types of codes read for example.

In embodiments, such as that shown in FIG. 1, the method 100 comprises, downstream from the encoding step 125, a step 145 of manufacturing a document representative of the encoding carried out.

This manufacturing step 145 is carried out, for example, by the implementation of computer software embedded in an electronic component of the software.

During this step, the document is generated and includes an indication of the completion of an encoding.

In embodiments, such as that represented in FIG. 1, the method 100 comprises, downstream from the encoding step 125, a step 150 of printing the encoded data.

The printing step 150 is carried out, for example, by implementing software for controlling a printer configured to print the data encoded by the second code.
