Definitions
- the present invention relates to the field of image recording, in particular for the production of accelerated films.
- An accelerated film (“Timelapse” according to English terminology) allows the observation of a phenomenon developing slowly.
- a succession of shots of a target phenomenon is made from a fixed or slowly moving location, each shot being spaced apart by a period of time chosen according to the dynamics of evolution. of the phenomenon.
- a daily succession of images of the building site is recorded, then mounted to 50 second images.
- Each second of the film corresponds to 50 days of construction of the site, and the order of 10 seconds of film then allows to represent in a lively and brief way the entire construction phase of the site.
- These films can have a promotional vocation or allow the study of natural or industrial phenomena particularly slow and therefore difficult to observe continuously.
- Known devices for producing an accelerated film are generally derived from conventional photographic cameras. As such, they have an image sensor associated with means for recording these images, such as a removable memory card. In some cases, the frame rate can also be programmed. But these known devices are not very suitable for the realization of accelerated film slow phenomena and therefore likely to last very long (several months or years).

- the known devices are therefore not autonomous in energy and in service.
- the devices remain stolen, even if they are positioned in a location that is difficult to access.
- the present invention aims to overcome certain disadvantages of the state of the art presented above. It aims in particular to provide an autonomous device for recording and image transmission particularly suitable for the production of accelerated film. BRIEF DESCRIPTION OF THE INVENTION

- the battery is chosen to have a good yield (little loss) even when exposed to high temperatures or temperature variations. It can be a LiFePo type 4 battery. This ensures a non-degraded autonomy when the autonomous device 1 is positioned outside for a long time.
- the management module 17 has the primary function of coupling the energy generator 2 to the storage means 16 to allow charging. This module 17 also provides all the energy management functions for the autonomous device 1 and has information on the storage means 16 (for example the level of charge of the battery or its temperature) and the generator 2 (for example the level of sunshine determined from the instantaneous energy produced by the generator). These data form moreover examples of control data of the device 1 which can be reassembled to the server S by the communication unit 13.

- the management module may have a microcontroller or a microprocessor, and its own information storage means for executing its own operating software independently of the control unit 11.
- the energy generation and storage unit 17 is able to temporarily supply the operating energy of the device from a predetermined time.
- this unit 17, via the management module is selectively coupled or decoupled from the other elements of the device, such as the control unit 11, the communication unit 13 and the sensor. image and the means of recording.
- predetermined instant it means a moment chosen in advance, preprogrammed. It is thus possible to provide the energy "just needed” to ensure the expected operation of the device.
- the autonomous device 1 may have dimensions sufficiently small to be contained in a volume defined by a cube 20 cm side. Its consumption can be reduced to less than lOWh per day, or even less than 7 Wh per day or even 5 Wh per day.
- the energy management module 17 is provided with a controllable switch for coupling the energy generation and storage unit 15 to the rest of the device 1 at a predetermined time (ie at least at the control unit 11, at the communication unit 13 and at the associated image sensor to the means of registration).
- the management module 17 or the controllable switch is provided with a real-time clock, for example of the RTC (according to the acronym "Real Time Clock"), as is well known per se.
- the housing may also be provided with a presence and / or motion sensor in order to receive activity information in the environment close to the housing.
- This information can for example be used by the control unit 11 and / or the energy management module 17 to trigger the awakening of the box and allow shooting or speed up the shooting rate.
- the awakening of the box can also be followed by sending the server information of presence and / or movement near the box, for example by integrating this information control information box.
- FIG. 3 there is shown a method of recording and transmission of images and / or control data, at a predetermined time, the autonomous shooting device 1 to a remote server S.
- the device is positioned to perform a succession of shots of a target phenomenon. It is also considered that the device is initially in standby state V, that is to say that only the generation and storage unit 15 is supplied with energy and that all the other elements of the device 1 are inactive.
- the predetermined time of shooting is stored in an information storage means of the management module 17 or the clock.
- the instant is identified, for example by comparing the time indicated by the clock of the management module at the instant predetermined and stored the next shot or waking phase of the device.
- This awakening event I which can be generated as an interrupt from the clock (or a signal from the presence and / or motion sensor) and to a microcontroller of the management unit 17, leads to initiate the execution of a program comprising a first step S1 for determining the level of energy stored in the generation and storage unit 15.
- step S2 if the stored energy level E is sufficient, that is to say if it is greater than a first predetermined threshold E1, the controllable switch is triggered and causes, during a step S3, coupling the generation and storage unit 17 to at least a part of the rest of the device, in order to supply the operating energy. If this is not the case, ie if the energy level E is lower than the first predetermined energy threshold E1, the coupling is not performed and the device returns to the standby state V, after having determined and memorized the next predetermined instant of awakening, during a step S4.
- the part of the device coupled to the unit 17 may consist of the control unit, the image sensor and the recording means. If the awakening of the device only targets the acquisition of data and their recordings, it is not necessary to couple the image sensors.
- the microcontroller / microprocessor of the control unit 11 then engages its startup program B, and proceeds in a first step S5 to the acquisition of an image and / or a control data item; then to his transfer in the means of registration.
- the acquisition of an image is performed only if the brightness is greater than a determined threshold.
- the value of the brightness can be estimated according to the energy level provided by the photovoltaic cell 2.
- the control unit 11 can signal to the management module 17 the END end of its activity.
- the energy level E is very insufficient, lower than the first predetermined threshold E1
- the step S4 of determining and recording the next predetermined instant may consist of a simple calculation of the next waking moment from certain control data (for example from the chosen frequency of shooting) or understanding the execution of a more complex algorithm of determination, aimed at estimating (for example from the state of charge of the battery and the degree of sunshine) the next time the stored energy level E is greater than the threshold E2.
- the algorithm can take into account historical sunlight information (from meteorological data base, or data collected by the box itself, or data collected by geographically close boxes) for estimate the next wake-up date allowing the feedback of the control information and / or images stored at the server, or to initiate a sequence of shots.
- the algorithm may use an ephemeris recorded in the recording means to establish the next predetermined waking moment allowing the shooting of a natural phenomenon, such as a sunset or a sunrise.
- the energy generation and storage unit can be coupled to all the elements of the device, and in particular to the communication unit 13. It is then possible to proceed during a step S7, in addition to the steps already described, to the transmission of the image or images, of the control data or of the control data of the recording means to the remote server S. Once transmitted, the images and / or data can be erased from the recording means to free space. They can also be kept for archiving or maintenance reasons.
- the transmission of images and / or control data continues until all the images and / or control data stored in the recording means have been transmitted to the server, and as the stored energy level E is greater than the threshold E2. If this level E comes to pass under the threshold E2, the transmission is then interrupted, and the transfer of the residual information postponed during a next phase of awakening.
- the law of sending images ie the choice of the quantity of images and / or data lifts during a wake-up sequence may be based on additional information such as:
- connection to the server The quality of the connection to the server, a good link (in terms of throughput) favoring a short connection time and therefore an optimal use of available energy.
- the instantaneous energy produced by the generator, witnessing good sunlight, this energy can be sufficient to perform the required operations without draining excessively stored energy.
- the transmitted control data may include the identifier of the autonomous device 1, the battery charge level as well as the current / voltage and temperature information of the battery, the time and date of the clock, the data of the battery. environment sensed by internal sensors (temperature sensor) or from devices associated with the device using the expansion connector ...
- control data from the server S may be received by the communication unit and stored in the recording means.
- the control data can correspond to a parameterization of the device (instant of the next or next shots, shooting frequency, image resolution, choice of the camera, threshold of brightness below which the taking of view is not performed, list of control data to be transmitted) and in this case, the control unit performs the settings of the relevant element of the device, during a step S8 of setting.
- the autonomous device 1 is provided with a geolocation unit 22, for example included in the communication unit 13.
- This data can be part of the control data transmitted to the server.
- Other control data stored in the means also can specify the initial or expected position of the device.
- the geolocation unit 22 may also have the function of updating precisely the date and time of the clock of the autonomous device 1, located for example in the management module 17.
- the method of the invention may then comprise, for example during step S7, the comparison between the actual position of the device (provided by the geolocation unit) and its expected position (stored in the recording means, and preferably in a non-volatile memory of the control unit 11).
- the control unit may place the device in a blocked, non-functional mode.
- This failover in blocked mode can be preceded by the sending of a message (to the server or by SMS directly to the user) in order to inform the user of the suspicious movement of the device, using the communication 13.
- this functionality is executed as soon as the energy level E is greater than the first predetermined threshold E1. It may therefore require a preliminary step of coupling the energy generation and storage unit 15 to the unit. 13 as soon as the energy level E is greater than the first predetermined threshold El.
- the device can be unlocked by connecting the device, for example via its USB or Bluetooth link, to a maintenance system (a computer or a tablet, for example) allowing it to be connected to the server without using the unit. communication 13 and its return to functional mode after identification of the user.
- a control system of the autonomous devices that have just been described, this system comprising a server in communication with a plurality of these devices.
- the server allows a user, connected by means of a computer, a tablet or a telephone, to take control of a device 1 to configure it, for example to a desired shot.
- a preliminary configuration and secure pairing step between an autonomous device 1 and a user identifier on the server S may be necessary.
- Each device 1 has a unique device identifier, stored in a non-volatile part of the recording means, for example within the control unit 11.
- the user's identifier is not held in the device, the association between the identifier of the device and the identifier of the user is held in a highly secure portion of the server S.
- the server offers a user a plurality of predefined configurations, in order to facilitate control of the device.
- the choice of one of these predefined configurations causes the sending of control information ensuring the chosen function.
- the server determines the optimal frequency of use of this device without it comes to run out of energy.
- the server can in this case suggest the optimal configuration parameters and / or transmit these parameters to the autonomous device during an upcoming connection.
- the period of shooting can be determined by the server based on an ephemeris and GPS position of the device (to take into account the effects of masking), and during this period of shooting the device can proceed to the acquisition of 5 to 10 images per second.
- a third example of a predefined configuration which is well adapted to the production of accelerated film of the building site, it is a question of adjusting the frequency of shooting (by increasing or slowing it down) according to the quantity of energy available in the device and taking care to avoid a depletion of this energy which would lead to a long period of standby of the device (without shooting).
- the autonomous device is provided with a test button (used mainly during installation or maintenance) which makes it possible to force the return to the remote server S of a shot and / or control data.
- the test button can also make it possible to force the autonomous device 1 to take into account new parameters placed on the server S.
- This button makes it possible to validate the proper functioning of the system: network coverage, camera framing. This button is functional only after one pairing of the device to a user and therefore after activation of the SIM card 24 of the communication unit 13.
- the server also allows the storage of images and control data received by the device. It can also provide the means for mounting an accelerated film from the repatriated images and making it available to a restricted audience or not.
