Abstract： At present, workpiece size detection mainly depends on mechanical measurement or manual measurement, which is difficult to detect and low efficiency. Aiming at that situation, this paper designs a set of non-contact object dimension and shape measurement system. The system uses STM32 as the core processor. OpenMV and laser ranging sensor are used as the non-contact detection unit to realize the function of measuring the color, shape, size and distance of the target object. At the same time, the direction of the laser tube in the system is controlled by the steering gear, so as to achieve the purpose of fast tracking the target object center. The experimental results show that the device can accurately measure the color and shape of the target object, obtain the size and distance of the object with high precision, and quickly track the center position of the target object.
