Abstract (en)
[origin: EP0854450A2] The tachometer disc records all speed changes into a plot Ä6Ü on a circular disc with the radial distance being proportional to speed Ä3Ü. In order to interpret the amount of data on the disc the image is enlarged and is scanned with the aid of a digital camera. Vector data is obtained and is entered into a file. This is then processed to obtain an interpretation of the journey.
