A wearable device is provided that is used while being worn on a body of a user. The wearable device includes a biometric-information authentication portion that acquires biometric information from the user for biometric authentication. The wearable device acquires biometric information from a portion in contact with or in the vicinity of the user's body to perform the biometric authentication without requesting the user to operate for the biometric authentication.

The invention discloses a piece of automatic walking equipment and a working region judgment method thereof. The method comprises the following steps: an image of a target region is shot; the image is divided into a plurality of sub image blocks; colors of pixels of at least one sub image block are extracted; the proportion of a predetermined color in the sub image block is calculated and compared with a first preset value; the texture feature value of the sub image block is extracted and compared with a second preset value; and a sub region corresponding to the sub image block is judged as the working region when the proportion of the predetermined color in one sub image block of the image reaches or exceeds the first preset value and the texture feature value reaches or exceeds the second preset value. Therefore, the working system is enabled to be simple and user-friendly, and working region identification is flexible and convenient.

For recognizing traffic signs that include a main sign and an associated additional sign, a method involves using a camera to record image data of an environment outside a vehicle, evaluating the image data to detect the presence and the class of the main sign and to detect the presence and partially classify the content of the additional sign by pattern recognition, performing text recognition to read and interpret text of the additional sign, and comparing the recognized text with actual current situational information to determine whether the main sign is currently applicable.

The invention discloses a semantic recognition method and device, and relates to the technical field of computers. The method comprises the specific steps that to-be-recognized statement information is acquired; the to-be-recognized statement information and preset statement templates are matched based on the longest common subsequence, and a matching result with a weight value is determined; semantic recognition is carried out according to the matching result. The method can perform more accurate semantic recognition on the acquired to-be-recognized statements on the basis of the matching method with the weight value of the longest common subsequence according to the preset statement templates, completely utilize statement template information, and be higher in flexibility and high in efficiency. In addition, the method can update the statement templates in real time in a short time to perform subsequent testing feedback.

The invention relates to a flexible production line based on visual inspection. The flexible production line comprises an upper computer, a control module, a visual inspection device connected with the control module and a workpiece conveying mechanism for conveying a to-be-inspected workpiece; the visual inspection device is erected on the workpiece conveying mechanism and inspects the to-be-inspected workpiece to identify defects; after the to-be-inspected workpiece is identified to have the defects, the control module controls a mechanical pick-up arm to pick up the to-be-inspected workpiece and transfers the to-be-inspected workpiece to another workpiece conveying mechanism; and the control module reports an inspection result to the upper computer. With the flexible production line, the workpiece inspection efficiency is improved by the aid of the visual inspection device, multi-angle images of the to-be-inspected workpiece can be acquired, the workpiece is inspected more comprehensively and flexibly, the defective workpiece is picked up automatically after being identified, and the production efficiency is improved.

The invention relates to the technical field of washing machines, and an objective is to solve problems that a fluorescent agent and / or pigments cannot be detected flexibly and conveniently, and accumulation of the fluorescent agent and / or pigments in a washing machine cannot be prevented. For this purpose, the invention provides a pollutant monitoring module used for a washing machine, a washingmachine, and a control method thereof. The pollutant monitoring module can be connected with a washing machine body in a detachable manner, and the pollutant monitoring module comprises an identification module. In a dismounted state and / or a connected state of the pollutant monitoring module, the identification module can identify pollutants in a detected object. The washing machine comprises thepollutant monitoring module. The control method comprises: making the pollutant monitoring module close to clothes or making clothes close to the pollutant monitoring module, to identify whether clothes pigments and / or the clothes have fluorescent agents; and according to information of the identified pigments and / or the fluorescent agents, recommending a washing program. The module can flexiblydetect the fluorescent agents and / or the pigments, and absorb the fluorescent agents and / or the pigments.

The invention relates to a flexible production line, comprising a control module, and an automatic discharging and feeding mechanism, a vision detector, a mechanical picking arm and a workpiece transferring mechanism for transferring workpieces to be detected, which are connected with the control module. The automatic discharging and feeding mechanism is used for conveying the workpieces to be detected to the workpiece transferring mechanism; the vision detector is arranged on the workpiece transferring mechanism in an erecting way, and used for detecting the workpieces to be detected; and when the defect of a workpiece to be detected is recognized, the control module is used for controlling the mechanical picking arm to pick the workpiece to be detected. According to the flexible production line provided by the invention, the workpiece detecting efficiency is improved through the vision detector; a multi-angle image of the workpiece to be detected can be acquired, so that the detection can be carried out more comprehensively and flexibly; and the defective workpiece is automatically picked after being recognized, so that the production efficiency is improved.

The present application provides a method and device for controlling a robot to grab an object, wherein the method includes: obtaining a target picture, the target picture contains a target mark, and the target mark is set on the target to be grasped; Identify the target, and determine the position information and attitude information of the target object, and the corresponding grasping scheme according to the target identity; then perform low-coupling kinematics solution to determine multiple joint variables; according to multiple joint variables and the corresponding grasping scheme, Control the robotic arm to grab the target. Because the scheme determines the position information and attitude information of the target and the corresponding grasping scheme by identifying the target mark set on the target; by using low-coupling kinematics to solve, calculate and obtain multiple joint variables; and then according to multiple joint variables and the corresponding grasping scheme to grasp the target, thereby solving the technical problems of the existing methods such as complex process of identifying the target, high cost, and low efficiency of calculating joint variables.
