The functional diagram of the mechatronic system for sorting and monitoring the quality of vegetables and fruit is given. The control objects were exposed to short-term thermal effects from sources of IR radiation during the movement on a roller table conveyor. The temperature fields of healthy control objects and damaged one by phyto-diseases or mechanical effects are different. This fact allows using a vision system based on a thermal imaging camera to detect subsurface defects for rejecting damaged control objects. Hyperspectral method of control was used for the surface defects detection. Defects detection algorithms in IR range images, as well as on the results of spectrogram processing, are given.
