Abstract

A system and a method for picking and placing objects, includes capturing at least one first image of at least one object at a first time point and at least one second image at a second time point; identifying the object in the first image and the second image; and obtaining first position information and second position information of the object; based on the first position information, the second position information, the first time point, and the second time point, calculating a moving speed of the object; calculating a target position and a target time point of the object based on the first position information, the second position information, and the moving speed; and controlling the machine arm to move at or to the target position at the target time point to pick the object.

Dependent claims

A method for picking and placing objects applied in a system for picking and placing objects, the system comprising at least one machine arm and a transmission device, the transmission device being configured to transmit at least one object in a predetermined direction, the method comprising:

capturing at least one first image of the at least one object at a first time point;
capturing at least one second image of the at least one object at a second time point;
identifying the at least one object in the at least one first image and the at least one second image;
and obtaining first position information and second position information of the at least one object;
based on the first position information, the second position information, the first time point, and the second time point, calculating a moving speed of the at least one object;
calculating a target position and a target time point of the at least one object based on the first position information, the second position information, and the moving speed;
and
controlling the at least one machine arm to move at or to the target position at the target time point to pick the at least one object.

A system for picking and placing objects, the system comprising:

a transmission device configured to transmit at least one object in a predetermined direction;
an imaging device arranged above the transmission device, the imaging device configured to capture at least one first image of the at least one object at a first time point and at least one second image of the at least one object at a second time point;
at least one machine arm configured to pick and place the at least one object;
and
an operating and processing module, the operating and processing module configured to:
identify the at least one object in the at least one first image and the at least one second image;
and obtain first position information and second position information of the at least one object;
based on the first position information, the second position information, the first time point, and the second time point, calculate a moving speed of the at least one object;
calculate a target position and a target time point of the at least one object based on the first position information, the second position information, and the moving speed;
and
control the at least one machine arm to move at or to the target position at the target time point to pick the at least one object.
