Abstract

The application relates to a system accuracy detection method, system and electronic device of a surgical mechanical arm, wherein the accuracy detection method comprises the following steps: determining a space transformation relationship between an execution component coordinate system in which an execution component is located and an image coordinate system in which an image acquisition device is located; controlling a terminal of the surgical mechanical arm to move to an actual pose based on a position of a target feature object, and acquiring feature object data in the image coordinate system collected by the image acquisition device for the target feature object at the actual pose; and converting the feature object data in the image coordinate system to the execution component coordinate system based on the space transformation relationship, so as to obtain a system accuracy result of the surgical mechanical arm. Through the application, the problems of low system accuracy detection efficiency and large human error of contact type measurement of the surgical mechanical arm are solved, and a system accuracy detection method of the surgical mechanical arm with high efficiency, high accuracy and strong anti-interference ability is realized.
