排球智练 vs PoseAnalyzer Motion Analysis

Want training feedback at the level of a professional volleyball player? Curious about how to improve your serving, spiking, or blocking techniques? Volleyball Smart Training — Uses AI video motion analysis technology to provide expert-level feedback on every training session. Upload your training videos, and the AI ​​analyzes body movements and technical mechanics to deliver detailed breakdowns—taking the guesswork out of your training. 【AI Video Motion Analysis】 Upload your volleyball training videos, and the AI ​​automatically captures key skeletal points. Based on biomechanical principles, it analyzes movements—such as serving, spiking, setting, and blocking—frame-by-frame, generating professional-grade reports that pinpoint exactly where improvements can be made. 【Four Key Training Scenarios】 · Serving — Focus on toss height and arm swing trajectory to boost consistency and aggressiveness. · Spiking — Analyze approach timing and arm-swing angles to increase power and placement control. · Setting — Optimize hand positioning and touch to improve setting accuracy and tactical coordination. · Blocking — Refine jump timing and hand positioning to increase block success rates and defensive coverage. 【Real-Time Motion Correction】 The AI ​​captures movement trajectories in real-time and compares them against standard technique models, providing instant feedback on deviations to help you make quick adjustments and train efficiently. 【Personal Progress Tracking】 An analysis report is automatically generated after every session, with a complete history saved. Track your progress clearly through data comparisons and ensure every training session is backed by objective insights. 【Exclusive Member Benefits】 Subscribe to unlock all training scenarios and in-depth analysis reports. Enjoy unlimited video analysis and receive more detailed technique breakdowns and personalized training recommendations.

PoseAnalyzer is a motion analysis app for physical education and sports coaching. From videos you shoot on your iPhone or iPad, it computes a person's skeleton, joint angles and center of mass (CoM) on the spot. All analysis runs on the device. Videos and data are never sent to external servers. ■ Shoot, select, analyze ・Record a trial and it appears in the list right away. ・Choose the range to analyze (start and end), then tap the box around each person you want to analyze (you can pick several). ・Only the selected people are tracked, so others in the frame never get mixed up. ・Analysis runs in the background. You can watch videos or record the next trial while you wait. ・If you stop an analysis midway, you can still see the results so far. ■ Quick result right after recording Skeletons estimated live during recording are shown with graphs as soon as you stop. When you analyze every frame later, they are replaced with the accurate result. ■ Result correction Fixes swapped left/right legs, removes outlier points, fills hidden points from neighboring frames, and smooths the motion. You can switch back to the uncorrected result at any time to compare. ■ What you can see ・Skeleton (26 Halpe-26 keypoints, including toes and heels) ・Joint angles (elbows, knees, shoulders and hips, left and right; knees are measured on the back side) ・Center of mass and its trajectory ・Graphs: show one or two of position, velocity, acceleration and joint angles (for the CoM or any keypoint) ・Frame stepping (also by tapping the screen edges), 0.1–2.0× speed, range looping, pinch to zoom ■ Real-length calibration Calibrate with two points of known length (for height: top of the head and the feet) or with the four corners of a rectangle on the floor and its diagonal, and position, velocity and acceleration are shown in m and m/s. ■ Center of mass fitted to the subject The CoM is calculated with body segment parameters that match the subject's age group, build and sex. Children's heads are relatively heavy, so adult parameters would place their CoM too low. ・Ages 3–15: Yokoi et al. (1986) (by build; by sex from age 9) ・Ages 16–18 and adults: Ae et al. (1992) ・Older adults: Okada et al. (1996) You can change the subject for each trial after analysis, and the CoM is recalculated immediately. ■ Export ・Video with the skeleton overlaid (saved to Photos), optionally with graphs and the original audio ・CSV (one row per frame: 26 keypoints with confidence, 8 joint angles, CoM) ・JSON (video information and data for every frame) ・The original video ■ Camera ・30 / 60 / 120 / 240 fps (as supported by the device) ・Standard and ultra-wide lenses, manual focus ・Live skeleton and CoM while shooting (up to 3 people) ・Delayed playback (shows the scene from 3–20 seconds ago, so athletes can check their own movement right away) ■ About the measurements Angles and the CoM are measured in the image plane as seen by the camera. Motion toward or away from the camera is not reflected. Real-length calibration is an approximation that assumes motion in a plane parallel to the camera. If you use the values for research or assessment, please keep these properties in mind. ■ Privacy All videos and results are stored on your device. No account is required, and nothing is sent to external servers.
