With one camera, without markers, and using a laptop, you can measure walking and check the results on the spot.
**Why can measurements be taken with a single camera without markers?** The joint positions during walking are determined using the following steps: - A depth camera captures the surface point cloud data visible from the camera. - Next, the standard human model stored in the computer is matched with the surface point cloud data. - From the matching results, the three-dimensional coordinates of the joint points can be obtained. - A simple calibration is performed to reduce errors caused by lens distortion. **Why can't walking measurements be taken with OpenPose?** - Recently, OpenPose has gained attention as software that estimates joint points (2D) from human appearance and data such as video footage. - While posture and skeletal estimation is indeed possible, it is considered difficult to obtain three-dimensional joint angles. **What can be measured with Anakin-Single?** The following measurement results can be confirmed on-site: - Stride length, walking speed, and cadence. - Walking posture viewed from various angles (displayed in stick picture format). - Changes in the position of various body parts and joint angles. **Prevention of dementia** Simply walking about 4 meters in everyday clothes provides immediate results.

basic information
**Why measure a person's posture and movements?** The ease or difficulty with which a person handles objects is unconsciously reflected in their posture and movements. Furthermore, the condition of a person's body is also manifested in their posture and movements. Therefore, measuring a person's posture and movements is extremely important for understanding the quality of objects and the state of the body. **What is measured without markers?** **Walking Measurement** - **Measurement Items** Walking speed, stride length, body tilt (forward/backward, side to side), head height, arm swing angle, shoulder and hip rotation, hip joint tilt (forward/backward, side to side), knee angle, foot extension/flexion, etc. - **Utilization of Data** By using the above data to evaluate the effectiveness of target products or services (such as rehabilitation or fitness guidance), it can be utilized in their development and design. **Movement Measurement (Usage)** - **Measurement Items** Body tilt (forward/backward, side to side), movements of arms and legs, shoulder and hip rotation, etc. - **Utilization of Data** By using the above data to evaluate the effectiveness of target products or services (such as sports instruction), it can be utilized in their development and design. For specific examples of individual usage, please refer to the details.
