Embodiment 1
[0031] Such as figure 1Shown is the three-dimensional dynamic test method and device schematic diagram of the tested electrical appliance between the high-speed camera and two mirror optical imaging systems, including the high-speed camera C, the high-speed camera fixture H, the mirror J1 of the optical imaging system, and the optical imaging system. Mirror surface J2, mirror surface fixing device F, electrical appliance under test A, moving part of the electrical appliance under test B, surface B1 of the moving part of the electrical appliance under test, surface B2 of the moving part of the electrical appliance under test, fixing device G of the electrical appliance under test, Computer system D, lighting system N. It is characterized in that: the mirror J1 of the optical imaging system and the mirror J2 of the optical imaging system are installed on the mirror fixing device F, the angle E between the mirror J1 of the optical imaging system and the mirror J2 of the optical i...
Embodiment 2
[0033] Such as figure 2 It is the three-dimensional dynamic test method and device schematic diagram of the high-speed camera between the tested electrical appliance and the two mirror optical imaging systems. The high-speed camera C and the tested electrical appliance A are both placed on the mirror J1 of the optical imaging system and the mirror J2 of the optical imaging system. In the front, the high-speed camera C is placed between the mirrors J1, J2 of the optical imaging system and the electrical appliance A under test.
[0034] Such as Figure 1 to Figure 3 As shown, B1 and B2 are the two tested surfaces of the moving part B of the tested electrical appliance, J1 and J2 are two mirrors, and the moving part B of the tested electrical appliance presents surfaces B1' and B2' respectively on the OP surface after mirror reflection . Adjust the high-speed camera to an appropriate position so that the B1' and B2' surfaces are imaged in the high-speed camera at one time, the...
Embodiment 3
[0036] Such as Figure 4 It is a three-dimensional dynamic test method and schematic diagram of the device in which the optical imaging system is a mirror, including a high-speed camera C, a high-speed camera fixing device H, a mirror J1 of the optical imaging system, a mirror fixing device F, the electrical appliance under test A, and the movement of the electrical appliance under test Part B, the tested surface B1 of the moving part of the electrical appliance under test, the tested surface B2 of the moving part of the electrical appliance under test, the fixture G of the electrical appliance under test, the computer system D, and the lighting system N, are characterized in that: the optical imaging The system has only one mirror, which is the mirror J1 of the optical imaging system. The tested surface B1 of the moving part of the electrical appliance under test faces the mirror J1 of the optical imaging system, and the tested surface B2 of the moving part of the tested elect...
