Map generation system and map generation method
An aspect of the invention is a map generation system including a three-dimensional data acquisition unit configured to acquire three-dimensional data from a scanning distance measurement sensor measuring a distance to a target to be measured, an operation information acquisition unit configured to acquire operation information representing an operation of a work machine occurring in a cycle of update of the three-dimensional data by the scanning distance measurement sensor, and a three-dimensional data correction unit configured to remove a portion corresponding to the work machine in the three-dimensional data based on the operation information.
1. A map generation system comprising:
a processor configured to:
acquire measurement data from a scanning distance measurement sensor measuring a distance to a target to be measured;
acquire operation information representing an operation of a work machine occurring in a cycle of update of the measurement data by the scanning distance measurement sensor; and
remove a portion corresponding to the work machine in the measurement data based on information interpolating between the operation information acquired at a scanning start time of the scanning distance measurement sensor and the operation information acquired at a scanning end time.
2. The map generation system according to claim 1 ,
wherein the information is a work equipment model to which an interpolation angle information for interpolating between angle information of work equipment of the work machine acquired at a scanning start time of the scanning distance measurement sensor and angle information of the work equipment acquired at a scanning end time is applied.
3. The map generation system according to claim 2 ,
wherein the processor is further configured to display an image in which an image based on measurement data with the corresponding portion removed is superimposed on an image captured by an imaging device.
4. The map generation system according to claim 1 ,
wherein the processor is configured to remove the portion corresponding to the work machine based on the operation information with a position of an end portion of a work tool of the work machine in the cycle of the update in the measurement data as a reference.
5. The map generation system according to claim 4 ,
wherein the processor is further configured to display an image in which an image based on measurement data with the corresponding portion removed is superimposed on an image captured by an imaging device.
6. The map generation system according to claim 1 ,
wherein the processor is further configured to display an image in which an image based on measurement data with the corresponding portion removed is superimposed on an image captured by an imaging device.
7. The map generation system according to claim 1 ,
wherein the operation information includes a position of the work machine and a posture of work equipment of the work machine.
