Abstract: A system for managing a motor vehicle parking area comprises a plurality of physical media bearing a unique bar code-type optical identifier, a QR code, or an RFID tag. Each physical medium is arranged on or in a motor vehicle. The system further comprises at least one camera for filming the vehicles, an analysis means running a program for analyzing the images sent by the camera to extract the unique optical identifiers, and a means for wireless communication between the analysis means and at least one human or robotic conveyor moving or transporting the vehicles associated with the identifiers, so as to send to the at least one conveyor a digital message indicating the destination address of the vehicle. A method may be employed using the system to manage the motor vehicle parking area.

Abstract: The present disclosure relates to a system for transporting articles or loads, the system being formed by at least one carriage comprising a platform provided with at least two axles supporting wheels, and a carrying vehicle, wherein the carrying vehicle is a self-propelled vehicle comprising a platform that can be slid underneath one of the carriages, the platform comprising means for lifting the carriage high enough to prevent contact of the wheels with the ground.

Abstract: The invention relates to a method for managing a fleet of autonomous parking robots by a supervisor. Each autonomous robot comprises a computer and a memory for storing a digital map of the parking space and geolocation means, environment sensors and means for telecommunication with said supervisor. The supervisor comprises a computer and a memory for storing a digital map of the parking space, as well as means for telecommunication with said robots, a record of a unique identifier of each of the robots, and a computer for computing the trajectories of said autonomous robots.

Abstract: A conveyor for moving four-wheeled vehicles comprises a telescopic frame provided with tire-chock arms movable between a retracted position and a position in which they engage with the treads of the wheels. The conveyor comprises a propulsion unit made up of a front frame to which two lateral subunits are secured, each comprising a motorized and directional wheel, which can be oriented independently of one another and a means for coupling the telescopic frame with the front frame.

Abstract: A method for managing an automatic parking lot involves determining a target space depending on an expected departure date of the vehicle, using a computation including allocating, to a new vehicle entering the lot, a target storage space according to the following rule: selection of spaces corresponding to one of the following criteria: o in the case where a row comprises at least one available proximal space, in front of a vehicle associated with a departure date after the departure date of the entering vehicle, o in the case where a row comprises at least one distal proximal space, positioning in a row the last vehicle of which is associated with a departure date before the departure date of the entering vehicle, allocating the target space to one of the selected spaces—otherwise allocating a space in a temporary storage zone including lanes of consecutive spaces.

Abstract: The disclosure relates to a conveyor for moving four-wheel vehicles. The conveyor includes a chassis having stowable extensions movable between a position in which the extensions make it possible to move the chassis under the vehicle and a position in which the extensions make contact with the treads of the wheels. The chassis is telescopic and includes two segments that each have a pair of arms. At least one of the arm pairs is hinged so as to enable movement between a position perpendicular to the longitudinal axis of the chassis with an extension at least equal to the track width of the vehicle and a folded-up position that is to occupy a width less than the distance between the inner flanks of the wheels of the vehicle. The segments are movable between a position where the arms are not in contact with the wheels and a position where each arm makes contact with the tread of one of the wheels so as to raise or lower the vehicle.

Abstract: A method of detecting the presence of an element (fog, rain, etc. . . . ) disturbing the visibility of a scene illuminated by a headlight (105, 107) at night. The method comprises: a) acquiring an image of the scene with the help of a camera (120); b1) detecting the light sources in the image; b2) detecting the presence of the disturbing element as a function of the halo (H) appearing in the image in the vicinity of the light sources; c) detecting the presence of the disturbing element in the image as a function of the backscattering of the light emitted by the light sources; and d) weighting the results of the detections performed in steps b2) and c) in such a manner as to output an indication concerning the presence of the element disturbing the visibility of the scene. The method provides satisfactory results in an environment with or without lighting. The invention also provides a computer program and a device for implementing the method.

Abstract: Devices and methods for detecting of drops on a transparent wall through which digital image is acquired by means of an image acquisition system. The method includes establishing a gradient image from the digital image by assigning to each pixel the value of the gradient for the pixel; filtering the gradient image by assigning to each pixel a value obtained by rank filtering; and establishing a mask representing the position of the detected drops in the digital image by activating the pixels for which the difference between the value of the pixel in the filtered image and the value of the pixel in the gradient image exceeds a predetermined value.
