Obtaining paving material mat characteristics
In some implementations, a control system may include at least one total station prism connected to a screed assembly of a paving machine, and a controller. The controller may be configured to obtain paving information that indicates locations of edges of a mat of paving material deposited by the paving machine. The paving information may indicate the locations of the edges based on data collected using the at least one total station prism. The controller may be configured to determine, based on the locations of the edges, an operating plan for one or more compactor machines that are to provide compaction of the mat. The controller may be configured to transmit, to another controller for the one or more compactor machines, plan information that indicates the operating plan.
1 . A method, comprising:
receiving, by a controller, location information relating to locations of one or more total station prisms connected to a screed assembly of a paving machine while the paving machine is performing a paving operation;
receiving, by the controller, paving information relating to a thermal profile of a mat of paving material deposited by the paving machine during the paving operation;
determining, by the controller, locations of edges of the mat of paving material deposited by the paving machine based on the location information and a distance offset between a position of the one or more total station prisms on the screed assembly and an edge of the screed assembly;
determining, by the controller and based on the locations of the edges of the mat, a pattern in which one or more compactor machines are to move with respect to the mat;
determining, by the controller and based on the thermal profile, a time duration for which the one or more compactor machines are to operate on the mat;
determining, by the controller and based on the locations of the edges, an operating plan for the one or more compactor machines that are to provide compaction of the mat, the operating plan indicating the pattern and the time duration; and
transmitting, by the controller to another controller for the one or more compactor machines, plan information that indicates the operating plan.

7 . A paving machine, comprising:
a screed assembly;
at least one detection component connected to the screed assembly, wherein the at least one detection component is a total station prism; and

determine locations of edges of the mat of paving material deposited by the paving machine based on the location information;
determine, based on the locations of the edges of the mat, a pattern in which one or more compactor machines are to move with respect to the mat;
determine, based on the thermal profile, a time duration for which the one or more compactor machines are to operate on the mat;
determine, based on the locations of the edges, an operating plan for autonomous operation of the one or more compactor machines that are to provide compaction of the mat, the operating plan indicating the pattern and the time duration; and
transmit, to another controller for the one or more compactor machines, plan information that indicates the operating plan.
8 . The paving machine of claim 7 , wherein the controller, to receive the location information, is configured to:
receive the location information from a total station operating using the total station prism.
9 . The paving machine of claim 7 , wherein the paving information further relates to one or more of:
a thickness profile of the mat, or
a speed profile of the screed assembly.
10 . The paving machine of claim 7 , wherein the screed assembly comprises:
a main screed;
at least one extension screed movably coupled to the main screed; and
at least one actuator configured to extend and retract the at least one extension screed with respect to the main screed.
11 . The paving machine of claim 10 , wherein the at least one detection component is connected to the at least one extension screed or the at least one actuator.
12 . A control system, comprising:
at least one total station prism connected to a screed assembly of a paving machine; and
