The invention relates to a fruit weight remote measurement device comprising a microprocessor, a touch screen, a high-definition camera and an infrared range finder. A software system comprises a fruit color identification module and a fruit size identification module based on a database. Real-time monitoring of fruits can be realized via the high-definition camera and the infrared range finder. Visual identification and quadratic spline interpolation curve methods are applied to perform identification and fitting on the contour of the fruits. The size of the fruits is calculated via establishing a reference curve, and the current weight of the fruit can be calculated to be displayed on the touch screen so that lossless remote control measurement of fruit weight is finally realized.
