The invention relates to a light source device for melon fruit vision measurement in the technical field of melon and fruit detection. The light source device comprises a two-degree-of-freedom adjustable gantry bracket, a PWM dimming driver, an annular front light source, an image acquisition module and a rectangular back light source, wherein the two-degree-of-freedom adjustable gantry bracket is provided with the PWM dimming driver and is provided with the rectangular back light source, the annular front light source and the image acquisition module from left to right in turn; the PWM dimming driver is respectively connected to the annular front light source, the rectangular back light source and the image acquisition module; and the image acquisition module is respectively connected to the annular front light source and the rectangular back light source. The light source device can provide a soft, uniform and pure white area light source so as to reduce the image distortion phenomenon; and the profile of m
