Measurement data collection device and program

A measurement data collection device comprising:

• a head-mounted display unit wearable on the head of a user;
• and
• a control unit configured to control the head-mounted display unit,
• the measurement data collection device being configured to collect a measurement value measured by a measurement tool handled by the user,
• wherein the head-mounted display unit includes,
• a frame wearable on the head of the user,
• a display screen of transmissive type supported by the frame at a position to cover a field of view of the user in a state where the head-mounted display unit is worn by the user and configured to display a three-dimensional image by superimposing the three- dimensional image on a real space, and
• a camera supported by the frame at a position to image the front of the user in a state where the head-mounted display unit is worn by the user,
• the control unit includes,
• a support information generation unit configured to generate a guide frame as support information, the guide frame being displayed in a reading position which is a suitable position of the measurement tool to be imaged by the camera,
• a display control unit configured to control the support information generated by the support information generation unit to be displayed on the display screen, and
• a measurement value reading unit configured to read a measurement value by analyzing an image of the measurement tool captured by the camera,
• the head-mounted display unit further includes a 3D sensor supported by the frame to face toward the front of the user in a state where the head-mounted display unit is worn by the user and configured to acquire point cloud data indicating a position of an object body in front of the user,
• the control unit further includes a three-dimensional information analysis unit configured to identify, based on the point cloud data acquired by the 3D sensor, a position of the measurement tool handled by the user, and
• the three-dimensional information analysis unit determines whether a measurement value display of the measurement tool is located in the reading position, and outputs a trigger signal for prompting the camera to capture the image of the measurement tool in response to a determination that the measurement value display is located in the reading position.

• the control unit further includes a three-dimensional information analysis unit configured to identify, based on the point cloud data acquired by the 3D sensor, a profile and a position of the measurement tool handled by the user,
• the control unit further includes a tool information storage unit storing a type of the measurement tool and a size, position, and/or shape of the guide frame associated with the type of the measurement tool,
• the three-dimensional information analysis unit refers to the tool information storage unit with the profile identified by the three-dimensional information analysis unit to identify the type of the measurement tool handled by the user and identify, in accordance with the type of the measurement tool, the size, position, and/or shape of the guide frame generated by the support information generation unit, and
• the support information generation unit displays the guide frame having the size, position, and/or shape identified by the three-dimensional information analysis unit on the display screen.
