Embodiment 1
[0034] Such as Figure 1 to Figure 3 As shown, a high-efficiency image measurement system in accordance with the present invention includes:
[0035] An image measurement unit, used to obtain the image information of the object under test;
[0036] Workbench, used to carry the DUT 4;
[0037] A plurality of position acquisition units, arranged on the image measurement unit and / or the workbench, are used to collect current position information and send it to the motion controller 11;
[0038] The motion controller 11 is used to drive the relative movement between the workbench and the image measuring unit;
[0039] The upper computer is used to read image information from the image measuring unit, and perform image processing and coordinate calculation to obtain geometric dimension measurement results.
[0040] Preferably, the image measurement unit is set on the Z slide 6, specifically including:
[0041] A camera 7, which acquires the image information of the DUT 4;

Embodiment 2
[0054] Such as Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that a position latch is further provided in the motion controller 11, and the position latch is respectively connected with the position comparator and the host computer. Since in embodiment 1, the photographing position is the set position, in fact, due to the signal delay, the camera 7 exposure photographing position will deviate from the set position. For this reason, a position latch is added. When the position comparator sends a signal, the position latch records the current position of the XYZ three-axis. Every time the host computer reads an image, it reads a position record from the position latch to ensure The strict correspondence between the image and the photographing position achieves the purpose of improving the measurement accuracy.
[0055] In the measurement process of the present invention, the start / stop action in the measurement process of the current image measu...
