The invention discloses a test device for a wide-angle module. The test device includes a tank body in which a spherical cavity is formed. A central light plate is arranged at the top center of the inner wall of the tank body. A channel for a lens of the to-be-tested wide-angle module to extend into is arranged at the bottom center of the inner wall of the tank body. The radius of the cavity is greater than or equal to a focusing distance of the to-be-tested wide-angle module. The side of the inner wall of the tank body is provided with at least four circumferentially and uniformly distributedperipheral light plates. The central light plate and the peripheral light plates are provided with at least one set of black and white line pairs. The distance between the central light panel and theperipheral light plates and the lens of the to-be-tested wide-angle module extending from the channel is the focusing distance of the to-be-tested wide-angle module. The test device, a test system and a test method for the wide-angel module can reduce the manufacturing cost and improve the testing efficiency of products.
