Abstract
In one embodiment, a dimension measurement apparatus has a camera a processing device. The processing device acquires a distance image of an object to be measured which is to be generated by the camera. The processing device divides the distance image into an X coordinate image, a Y coordinate image, and a Z coordinate image, removes a coordinate point not corresponding to one reference surface of the object to be measured, in the respective coordinate images, and detects coordinate images of the reference surface corresponding to the reference surface.
Claims10
A dimension measurement apparatus, comprising:
- a camera which photographs an object to be measured to generate a distance image of the object to be measured;
- and
- a processing device which generates dimension data indicating a length, a width, and a height of the object to be measured, based on the distance image generated by the camera;
- the processing device having a memory to store a control program for generating the dimension data and a controller;
- the controller executing the control program,
- to acquire the distance image of the object to be measured,
- to divide the acquired distance image into an X coordinate image, a Y coordinate image, and a Z coordinate image in a three-dimensional space,
- to remove a coordinate point not corresponding to one reference surface of the object to be measured, in the respective divided X coordinate image, Y coordinate image, and Z coordinate image, to detect an X coordinate image, a Y coordinate image, and a Z coordinate image of the reference surface, and
- to generate the dimension data indicating the length, the width, and the height of the object to be measured, based on the respective detected coordinate images of the reference surface.
A control method of a dimension measurement apparatus having a camera which photographs an object to be measured to generate a distance image of the object to be measured, comprising:
- acquiring the distance image of the object to be measured which has been generated by the camera;
- dividing the acquired distance image into an X coordinate image, a Y coordinate image, and a Z coordinate image in a three-dimensional space;
- removing a coordinate point not corresponding to one reference surface of the object to be measured, in the respective divided X coordinate image, Y coordinate image, and Z coordinate image, to detect an X coordinate image, a Y coordinate image, and a Z coordinate image of the reference surface;
- and
- generating dimension data indicating a length, a width, and a height of the object to be measured, based on the respective detected coordinate images of the reference surface.
