The invention relates to a limb dimension real-time measurement method and device and computer equipment. The method comprises the steps of obtaining current shape structure data of a limb of a user, and generating a current limb structure model of the limb based on the current shape structure data of the limb; based on the current limb structure model of the limb, through a light ruler structure modeling strategy, generating a current light ruler measurement model, and based on the current light ruler measurement model, adjusting a light ruler measurement device to obtain a current light ruler measurement device; and carrying out dimension measurement processing on the limb through the current optical ruler measurement equipment to obtain current dimension data of the limb, and generating a current dimension measurement result of the limb through a historical limb dimension database based on the current dimension data of the limb. By adopting the method, the limb dimension measurement accuracy can be improved.

The application relates to an early pregnancy prenatal ultrasound four-limb standard section image acquisition method, which comprises the following steps: in the early pregnancy prenatal detection process, inputting four-limb section ultrasound images in a real-time ultrasound video stream into a target prediction model to detect each sub-limb structure in the four-limb section ultrasound images and predict a first image quality score of each sub-limb structure; determining a corresponding sub-section type of the four-limb section ultrasound images under a four-limb section type according to the detected each sub-limb structure; determining an image quality score of each four-limb section ultrasound image based on the first image quality score of each sub-limb structure in the four-limb section ultrasound image; in the case that the four-limb section ultrasound images corresponding to the same sub-section type in the video stream are multiple, selecting a standard section image under the sub-section type from the multiple four-limb section ultrasound images of the same sub-section type based on the image quality score. The method can automatically select high-quality early pregnancy four-limb standard sections in real time.

The invention relates to a pneumatic artificial muscle nerve teaching model and system, which are combined with a pneumatic artificial muscle nerve teaching model technology and adopt an aluminum alloy frame and a 3D printing bone surface model to construct a limb structure. The system receives an instruction through the voice recognition module, the Arduino controller coordinates the LED lamp strip display system and the dual-motor driving system, and nerve conduction path visualization and joint precise control are achieved. Innovation points comprise multi-mode interaction, pathological phenomenon quantitative simulation (folding knife phenomenon / spasm / ankylosis), muscular tension grading and safety mechanism design. The application scene covers basic anatomy teaching, neuroscience learning, rehabilitation training and clinical skill assessment, supports Ashworth grading comparison and upper motor neuron injury simulation, improves teaching immersion and clinical association ability, and has the characteristics of modular design, convenience in maintenance and upgrading, safety and reliability.

The invention discloses a limb structure of a robot and the robot, and belongs to the field of robots. The limb structure comprises a main limb, two ends of which are respectively provided with a joint connecting part; the two joint assemblies are connected to the two joint connecting parts respectively, and each joint assembly and the corresponding joint connecting part form a connecting rod mechanism; the two telescopic components are arranged corresponding to the two joint connecting parts, one end of each telescopic component is hinged to the joint assembly, the other end of each telescopic component is hinged to the main limb, and the length of each telescopic component is adjustable so as to drive the connecting rod mechanism connected with the telescopic component to act. According to the limb structure, profiling is easy, supporting on the joints can be improved by means of the main limb body, particularly, impact on the joints is reduced when loads change, and the situation that the damage risk is large due to the fact that the driving pieces are concentrated on the joints, and joint stress concentration is caused is avoided.

The utility model relates to the technical field of doll equipment discloses a doll skeleton, including torso structure, four limbs structure and connecting structure, be provided with two shoulder connecting parts and two crotch connecting parts on torso structure, two shoulder connecting parts and two crotch connecting parts are arranged respectively in the opposite two ends of torso structure, four limbs structure includes at least two arm assemblies and at least two leg assemblies, one end of any arm assembly is adapted to be connected with a shoulder connecting part, one end of any leg assembly is adapted to be connected with a crotch connecting part, connecting structure is arranged between torso structure and arm assembly and between torso structure and leg assembly, wherein, torso structure, arm assembly and leg assembly are configured as hollow cavity structure, and all adopt plastic grease material, the utility model can reduce the use amount of soft filling in the doll, and reduce the density and weight of the formed doll made of the skeleton, to facilitate user to use, and improve the experience effect of user.
