1. A method for trajectory processing, comprising:
generating a trajectory diagram of a real space by using sensor data of a ranging device, the sensor data including angle information and distance information obtained by the ranging device when the ranging device travels at the real space;
displaying, on a graphical user interface, a plurality of trajectory diagrams of multiple spaces, wherein each space corresponds to at least one of the trajectory diagrams, and the plurality of trajectory diagrams includes the generated trajectory diagram of the real space;
determining a target space on the graphical user interface, wherein a perimeter of the target space being formed by boundaries of two or more spaces of the multiple spaces;
determining attribute information of the two or more spaces, wherein the attribute information of a space includes at least an area of the space calculated based on one or more of the trajectory diagrams that correspond to the space;
determining an area of the target space based on the areas of the two or more spaces;
assigning a same type of construction object to at least two spaces, comprising:
identifying the at least two spaces based on a user selection operation on the graphical user interface;
displaying, on the same graphical user interface that presents the plurality of trajectory diagrams of the multiple spaces, icons of candidate construction objects;
displaying, based on a target icon selected by a user among the icons of the candidate construction objects, that the at least two spaces correspond to a target construction object indicated by the target icon; and
in response to the target icon being selected, displaying, on the same graphical user interface that presents the plurality of trajectories diagrams of the multiple spaces, a plurality of candidate vendors, and information about specification and price of the target construction object under each candidate vendor; and
displaying total construction information for the at least two spaces based on the area of each of the at least two spaces and target construction object information of the same target construction object.
