Active-passive composite micro-vision guide robot micro-assembly system and method

The invention discloses an active and passive composite micro-vision guide robot micro-assembly system and method, and the system comprises a DLP projector, a high-resolution industrial camera, a common industrial camera, a double-magnification telecentric lens, a common telecentric lens, a precise positioning robot, a working platform, an operation robot, an end effector, a common positioning sliding table, an imaging system supporting device, and the like. Coarse positioning of a target in a plane is achieved through a high-resolution industrial camera, and the precise positioning robot is guided to move the target to the center of the plane; projecting a coding pattern through a DLP projector, and triggering a common industrial camera to collect an image containing coding information; carrying out decoding algorithm processing on the image containing the coding information, and obtaining a three-dimensional point cloud of the target by using a three-dimensional reconstruction algorithm in combination with
