VueMotion uses a patent-pending cone calibration system designed to achieve lab-grade biomechanics accuracy through smartphone-based video analysis.
To ensure the reliability of results, correct cone setup is crucial. VueMotion introduces a world-first virtual cone system that automatically validates the setup and provides instant feedback within the app.
The 'Check Cones' functionality reviews the cones set up for 5 conditions and gives instant feedback on setup. Also, it allows using non-recomended cones which the system can use if 9-inch yellow cones are not available. The cones set up is saved automatically and uploaded to be used while processing the video.
The diagram below shows acronyms for different cones and important scene geometry aspects.
VueMotion’s 5-cone configuration enables accurate calibration and spatial understanding of the scene for motion capture.
The setup includes:
Left Cones:
Left Far (LF)
Left Close (LC)
Right Cones:
Right Far (RF)
Right Close (RC)
Mid Cone (MF):
Positioned in line with LF and RF, at the center of the running lane.
Running Track
The region between the cones defines the running track. The central white line represents the direction of motion, and both Left-to-Right and Right-to-Left running modes are supported by VueMotion.
Cones are placed as a 5-point setup: two on the left, two on the right, and one in the middle.
The camera is centered on the mid cone and aligned to the far cones.
The field of view should cover at least 1.5 meters on both sides of the cones to ensure the entire stride cycle (including back leg movement) is visible.
(the yellow cones look as a square from the top)
The cones are centred in the camera field of view with the camera and the middle cone aligned. The 1.5m region on either side of the cones is left to include back leg in the acceleration test.
VueMotion performs the following five automated setup checks before analysis begins.
Each test provides real-time feedback through the app.
This test checks if the Far Cones and Close cones are parallel to each other and to the running track (which is assumed to be the horizontal line of the camera axis)
Some other cases which are possible and tested :
The camera is asked to be tilted if the test is not passed (tilt right or left) or cones to be readjusted if they are not in line (camera tilt alone will not fix misaligned cones).
Objective:
Ensure that the Far Cones and Close Cones are parallel to each other and to the running track (camera’s horizontal axis).
Feedback:
If cones are not parallel, the app will recommend readjusting the cones.
If misalignment is caused by camera tilt, users are instructed to tilt the camera right or left as needed.
This test checks if the camera axis and cones line are parallel or not.
Objective:
Verify that the camera’s horizontal axis is parallel to the cone alignment line.
Feedback:
If the cones appear skewed in the frame (points 6 and 7 misaligned), the app prompts the user to adjust camera tilt until both sides appear level.
The cones position 6 and 7 represent center points of left and right cones respectively.
Test 3 checks if mid cone is in middle of left and right cones. If not, user is asked to align mid point cone.
Objective:
Confirm that the Mid Cone (MF) lies exactly midway between the left and right cone lines.
Feedback:
If off-center, users receive on-screen guidance to reposition the mid cone along the central running line.
The test 4 checks if the middle cone is aligned with the middle of the camera axis. If not, feedback is given to shift the camera to right (case 1) or left (case 2)
Objective:
Validate that the Mid Cone aligns with the camera’s central axis.
Feedback:
If the mid cone appears right of center, users are prompted to move the camera left.
If it appears left of center, users are prompted to move the camera right.
Objective:
Ensure the camera distance from the cone array is optimal (recommended 1.5 m beyond the outermost cones).
Feedback:
If the camera is too close, the app instructs to move it backwards.
If too far, users are guided to move the camera closer to maintain frame coverage.
Go to Recording Screen via 'Record and Import Video' (camera icon in the middle)
Click the Recording Mode
Go to Step 2
By Default, Instant Cone Setup Feedback screen opens up.
More Info -> brings you to this page.
Check Cone Set Up -> Will show digital cones (see step 3)
Go to Recording -> Skip cone set up and do a quick recording
If you click -'Check Cone Set up' in step 2, the next screen shows:
A blue grid to show you center of the screen (vertical blue line) and horizontal blue line to show you the tilt of the camera.
Also, 5 cones appear on the screen which can be moved via touch-n-move to overlapp with real-world markings
The results and recommendations are displayed, once you click 'Check Cones'.
The cones positions are saved as well to allow AI processing.
If you do not want to test cone configuration, please select 'Remove Cones' and continue to recording as before.
