摘要:
Apparatus to acquire an image of roots of a plant located in a target rhizotron, said apparatus comprising:- a turntable (12) having a rotation axis (X) and intended to support said target rhizotron;- a lightening device (14);- an first camera (16) having an optical axis (O) substantially oriented toward said rotation axis (X), said first camera comprising a plurality of elemental light sensors, each elemental light sensor being configured to acquire a respective elemental signal (S52);- a control module (20) configured toi) determine an elemental time period (Δt) as a function of- a rotation speed (ω) of the turntable around said rotation axis, and- a distance (D) between said elemental light sensors and said target rhizotron and/or the zoom magnification of the first camera;ii) control the elemental light sensors to generate pixel signals from said elemental signals (S52), each pixel signal starting at an initial pixel tick, lasting for said elemental time period (Δt), and finishing at a final pixel tick;iii) parameterize a pixel of an image according to a respective pixel signal.
