The device consists of a pedestal, a product bracket, a flexible shielding cover, a lens set parallel optical tube, a video test pattern card and a lighting lamp box; the product bracket is arranged at one end of the upper part of the pedestal; the vidicon is arranged on the product bracket; one end of the flexible shielding cover is arranged at one side of a vidicon lens; the other end of the flexible shielding cover is connected with the lens set parallel optical tube; the rear part of the lens set parallel optical tube is provided with the video test pattern card; and the rear part of the video test pattern card is provided with the lighting lamp box. The video test pattern card is set and can detect resolution, grey scale, image evenness and the like; and different test projects can be detected through replacement of the video test pattern cards with different contents. The device and the method have simple and clear detection process, are suitable for batch detection of vidicon products and can operate outdoors or in severe environment.

Description

A kind of camera optical performance pick-up unit and detection method
Technical field:
The present invention relates to pick-up unit, especially a kind of camera optical performance pick-up unit and detection method.
Background technology:
At present, the resolution of video camera, gray shade scale, image homogeneity etc. are important performance index, processing, debug, need detect these projects when environmental test, Product Acceptance Review.
The device that detects camera optical performance both at home and abroad mainly is that video measurement graph card (the transmission-type test pattern adds lighting lamphouse) and sliding support, parallel light tube and sliding support and product sliding support are set respectively on the optics guide rail, video camera is installed on the product shelves, distance between 3 sliding supports of meticulous adjusting accurately is arranged on the focal plane of video camera test pattern and obtains distinct image signal; Picture signal shows on monitor, and the numerical value that reads maximum chequered with black and white striped from display screen is called the resolution of this video camera; Also can measure performance index such as gray shade scale, brightness uniformity by comprehensive frequency test pattern.There is following deficiency in this pick-up unit:
(1) volume is long, and weight is big, is difficult for moving and carrying;
(2) state of each sliding support changes easily, often needs to proofread and correct again;
(3) the light path opening is subject to the interference of ambient light, is difficult to read the actual highest resolution of video camera;
(4) testing process complexity, time and effort consuming when being used to detect bulk article.
The present invention provides a kind of camera optical performance pick-up unit and detection method in order to overcome the above problems.
Summary of the invention:
Pick-up unit
The present invention is a kind of small-sized whole detection device that camera optical performance detects that is used for, as shown in Figure 1.This device mainly is made of pedestal, lens combination parallel light tube, flexible light shield and camera mount; The visual field of lens combination parallel light tube adapts to the needs of camera field of view, and the video measurement graph card is set on the focal plane of lens combination parallel light tube, and the video measurement graph card adds lighting lamphouse behind.Product shelves is arranged on an end of pedestal top, and the video camera dress is placed on the product shelves, and flexible light shield one end is arranged on camera lens one side, and the other end is connected with the lens combination parallel light tube.The distance of product shelves and lens combination parallel light tube should guarantee that four edges that video camera absorbs the video measurement graph card just are full of monitor screen.
Detection method
Video camera is installed on the product shelves, by the figure on flexible light shield and the lens combination parallel light tube picked-up video measurement graph card and on monitor, show; The numerical value of the maximum chequered with black and white striped that can read from the video monitor is the resolution of this video camera; Maximum grey levels that can read are the gray shade scale of this video camera; The image resolution ratio of observation center and four jiaos is judged the image homogeneity.
The video measurement graph card of changing different content can detect different test events.
The optical axis center of lens combination parallel light tube is parallel with base plane B with the formed straight line A in video measurement graph card center, and the register pin of product mounting bracket and precision guarantee that all the optical axis center of video camera overlaps with the optical axis of lens combination parallel light tube (straight line A); Flexible light shield guarantees that video camera is light tight to the sealing of the light path between the lens combination parallel light tube, and difform video camera is equipped with corresponding mounting bracket.
Beneficial effect:
The invention has the beneficial effects as follows:
(1) volume is little, and is in light weight and integrated, is convenient to carry and carry;
(2) each assembly is fastening, and long-term use does not need frequent correction;
(3) adopt flexible light shield, make the airtight influence that is not subjected to extraneous light of light path;
(4) testing process is simple and clear, is applicable to the batch detection of video camera product, can work under outdoor or rugged surroundings.
Description of drawings:
Below in conjunction with accompanying drawing the present invention is further described.
Fig. 1 is device general assembly structural representation of the present invention.
