Not exactly the same, but combining radio tower triangulation, GPS and measuring and adjust accelerometer errors over time - you should be able to enhance position data. Accelerometers combine an accurate variability of movement measure with a non-invasive, portable method of measurement1. You convert images to grayscale (compensating for different light entensities), then implement thresholding, image enhancement, on the images (to compensate for images getting blurred while walking), then corner detection (increase accuracy for total result estimations), then template matching which does the actual comparing between image frames and estimates actual displacement in amount of pixels. With the phone fixed and rotated about a single point, as the sensitivity of one axis increases, the sensitivity of the perpendicular axis decreases (Fig. Moreover, we found that the fingerprints persist even if the vibrations are subjected in less controlled settings, e.g., when the user is naturally holding an accelerometer-equipped phone. 0000003048 00000 n I done a few tests by walking a certain distance (with a slow and steady walk speed, to cancel out video blurring effects, but to see true accuracy with pixel displacement calculations) and comparing the pixel displacement results of each test.This was on a evenly colored carpet. So hope this helps... otherwise google for Egomotion for real-time applications. I have only a superficial understanding of techniques like Kalman filters to correct for drift, though if such techniques are relevant to my application and someone wants to describe the quality of the corrections I might get from such techniques, that would be a plus. There are hundreds of parts to choose from with a significant span in cost and performance. Accelerometers are capable of measuring acceleration, tilt, and vibration or shock, and, as a result, are used in a diverse range of applications from wearable fitness devices to industrial platform stabilization systems. endobj <> 0000007879 00000 n Just about every phone on the market will come with either a … The whole "trick in the code" is to perfect your thresholding implementation (for template matching).

I have another approach possibly plausible, if you're interested in proceeding with your project. We conducted a prospective observational study which aimed to investigate the accuracy of the most popular free of charge pedometer applications available for download to mobile phones equipped with an accelerometer. The new Android version (GTR) adds accelerometer support for even more accurate and reliable results. This isn't because the accelerometers themselves are poor, but because the orient… We have also conducted experiments subjecting smartphones to rotational motion instead of vi-bration, which too affirmed accelerometer diversity. Types of Accelerometer. Even though endstream Exactly what this is depends on how far you want the device to travel. Eventually you'll get the right stuff and figure out the jibberish I just explained to you. To get good rotation accuracy, you can add a … Sloppy mounting results in a reduction in the mounted resonant frequency, which can severely limit the useful frequency range of the accelerometer. If you only want to travel a metre or so, I recommend forgetting about the IMU and using a magnetic trcker like the miniBIRD. The accelerometer is a device that can measure the force of acceleration, whether caused by gravity or by movement. Here is an explanation why (Google Tech Talk) at 23:20. Without having a second point of reference (2 cameras) you can't reconstruct where you are directly because of depth. 0000007216 00000 n Optical flow, or as called by a view, Ego-Motion.
