Camera device for workout
An exercise machine includes a cable. It further includes an interface to a moveable camera device coupled with the exercise machine. It further includes a processor configured to receive a cable-based measurement associated with an exercise performed by a user. The processor is further configured to receive, from the moveable camera device, video information associated with the exercise. The processor is further configured to provide a workout determination based at least in part on both the cable-based measurement and the video information received from the moveable camera device.
1. An exercise machine, comprising:
a cable;
a motor coupled to the cable to provide resistance during an exercise performed by a user;
an interface to an external camera device coupled with the exercise machine; and
one or more processors configured to:
receive cable-based measurements associated with the exercise performed by the user, wherein the cable-based measurements are is based at least in part on cable position data associated with the cable coupled to the motor, and wherein the cable position data is measured at least in part by a position encoder
receive, from the external camera device, key points generated by the external camera device from captured video frames video information-associated with the exercise, wherein the key points correspond to one or more points of the user, wherein the key points are associated with timestamps, and wherein at least one of the external camera device or the exercise machine is configured to perform interpolation to generate a synthetic key point;
map a portion of the received key points to a corresponding portion of the cable-based measurements at least in part by performing synchronization using the timestamps associated with the received key points; and
provide a workout determination based at least in part on the mapping of the portion of the received key points to the corresponding portion of the cable-based measurements.
2. The exercise machine of claim 1 , wherein the key points are batched together by the external camera device.
3. The exercise machine of claim 2 , wherein the batch of key points is transmitted by the external camera device based at least in part on a phase of an exercise repetition being performed.
4. The exercise machine of claim 1 , wherein the external camera device is wired to, or wirelessly coupled with, the exercise machine.
5. The exercise machine of claim 1 , wherein at least one of the external camera device or the exercise machine is configured to perform smoothing of the key points at least in part by aggregating a window of video frames.
6. The exercise machine of claim 1 , wherein the exercise machine is configured to provide to the external camera device an indication of a start of the exercise.
7. The exercise machine of claim 1 , wherein the external camera device comprises a mobile phone, and wherein the mobile phone comprises a mobile application.
8. The exercise machine of claim 1 , wherein the one or more processors are configured to determine whether an amount of the key points is below a threshold.
9. The exercise machine of claim 1 , wherein the workout determination comprises at least one of form feedback, rep counting, range of motion (ROM), flexibility, struggle detection, or fatigue detection.
