SolGrader didn’t detect all potatoes after taking a picture

Try to follow the tips below:

– hold your phone as steady as possible,
– align the white corners with blue mat corners and a cross with a red square,

– keep the red square visible and 2 cm free space from its edges,

– potatoes should not be too close or on the edges of the blue mat,

– potatoes should not be “touching” each other,

– keep the blue mat relatively clean,

  When there are other objects on the blue mat like dirt,
  small branches, they may be detected and measured as well,

– place a smaller amount of potatoes on the blue mat,

– avoid placing the mat directly in the sun, as strong shadows will affect the measurement.
