METHOD AND DEVICE FOR IMAGING A PLANT, AND METHOD FOR DETERMINING A CHARACTERISTIC OF A PLANT

The invention relates to a device (10) for acquiring images of a plant, which comprises: - i) a first structure (60) that delimits a cavity (33) for receiving a plant part to be imaged, the cavity having a longitudinal axis (13) and an opening (65) at one of its ends and being delimited by a transpa...

description The invention relates to a device (10) for acquiring images of a plant, which comprises: - i) a first structure (60) that delimits a cavity (33) for receiving a plant part to be imaged, the cavity having a longitudinal axis (13) and an opening (65) at one of its ends and being delimited by a transparent wall forming a window (12) for observing the part to be imaged; - ii) a second structure (61) that extends around the window (12) and is mounted so as to be movable in translation along the longitudinal axis (13) with respect to the first structure, said second structure comprising: - a recessed reflective optic (11, 19) that extends around the window and has a reflective surface (19) directed towards the longitudinal axis; - a plurality of image sensors (18) distributed regularly around the window (12), the field of view (77) of each sensor including at least a part of the reflective optic so as to capture images of the plant part surrounded by the window which are reflected by the reflective optic; - iii) an actuator (64) for driving the second structure in movement with respect to the first structure, along the longitudinal axis.
