机械臂深度配准出现了问题

[821234877]

老铁们，这个问题怎么解决？

ros@ubuntu:~/catkin_ws/src/robot_sim/experiment/depth_image_registration/src$ g++ ./depth_image_registration.cpp -o depth_image_registration $(pkg-config --cflags --libs opencv)
./depth_image_registration.cpp:4:28: fatal error: opencv2/core.hpp: No such file or directory
compilation terminated.
