The physical properties of seeds especially spill property are very important in practice. According to the requirement of spill property measurement, a measurement system of seeds gravity angle based on MC9S12DG128 microcontroller was developed. The system consisted mainly of measurement device, motor driving unit, angle measurement unit, image acquisition unit and the microcontroller unit including the LCD for display the results. The measurement principle and working process of the system were introduced in the paper. Image acquisition and segmentation was employed to evaluate the seeds flowing situation. The measurement system was validated by comparing the results obtained by the system to the ones evaluated manually on peas. The experimental data showed that the results given by the system were in accordance with those provided by manual measurements.
