It is defined in a attached drawing, then in subsequent attached drawing does not need that it is further discussed.
The Camera Test method of explanation automatic positioning test pattern provided in an embodiment of the present invention shown in Figure 1, packet
Include following steps：
101, fisrt feature region is detected from the test image that camera to be measured is shot, determine that fisrt feature region exists
Coordinate in the test image of camera shooting to be measured.
Shown in Figure 7, by taking color test pattern A (color CHART) as an example, color test pattern A has multiple features
Region a1-a18, respectively represents different colours.The test image of camera shooting to be measured is C, it can be seen that color test pattern A
It is slightly displaced from, is not imaged on the center of test image C；In the prior art, it needs to manually adjust camera to eliminate
Such case is to remove imaging error, but the present invention does not need to carry out this operation.In a step 101, it can choose characteristic area
Domain a1 is fisrt feature region, detects fisrt feature region a1 from the test image C that camera to be measured is shot, determines first
Coordinate of the characteristic area a1 in test image C.
102, the coordinate according to fisrt feature region in the test image that camera to be measured is shot and fisrt feature area
The positional relationship of domain and other feature region in the test image that camera to be measured is shot determines other feature region to be measured
Coordinate in the test image of camera shooting.
Shown in Figure 7, by taking color test pattern A (color CHART) as an example, step 101 has been detected by fisrt feature
Coordinate of the region a1 in test image C, then can be according to fisrt feature region a1 and characteristic area a2-a18 in test image C
In positional relationship, determine coordinate of the characteristic area a2-a18 in test image C.For example, color is surveyed in test image C
Attempt each characteristic area in card A and its distance between characteristic area is x up and down, then can be according to fisrt feature
Region a1 calculates coordinate and characteristic area a3-a18 of the characteristic area a2 in test image C in the coordinate in test image C
Coordinate in test image C.
103, the coordinate according to each characteristic area in the test image that camera to be measured is shot is clapped from camera to be measured
Each characteristic area is extracted in the test image taken the photograph, and generates test result.
The embodiment of the present invention uses and determines that test pattern is specifically sat calibration method and taken the photograph to make up according to test pattern feature
As head is taken pictures deviation caused by central region offset, saves and adjust camera by manual methods and take pictures central region, shorten
Testing time substantially increases testing efficiency.
The Camera Test method of explanation automatic positioning test pattern provided in an embodiment of the present invention shown in Figure 2, packet
Include following steps：
201, fisrt feature region is detected from the test image that camera to be measured is shot, determine that fisrt feature region exists
Coordinate in the test image of camera shooting to be measured.
Shown in Figure 7, the test image of camera shooting to be measured is C, it can be seen that color test pattern A is slightly inclined
It moves, is not imaged on the center of test image C；In the prior art, need to manually adjust camera to eliminate this feelings
Condition is to remove imaging error, but the present invention does not need to carry out this operation.In step 201, the survey shot from camera to be measured
Attempt to determine fisrt feature region a1 in the test image C that camera to be measured is shot as detecting fisrt feature region a1 in C
Coordinate.
202, coordinate and fisrt feature region of the fisrt feature region in the test image that camera to be measured is shot are calculated
The deviation of coordinate in standard testing image executes step 203.
Shown in Figure 6 is standard testing image, it can be seen that color test pattern A is imaged on standard testing image B's
Center.In step 202, coordinate of the fisrt feature region a1 in standard testing image B and fisrt feature region are determined
Deviation of the a1 between the coordinate in test image C.
The progress of standard camera head can be used, and shooting obtains standard testing image in advance：Standard camera head is first moved to survey
Attempt the central region for being positioned in the standard camera head, then shooting obtains standard testing image；Standard testing image is carried out
Detection, determines coordinate of the fisrt feature region in standard testing image, further, can also determine other each characteristic areas
Coordinate of the domain in standard testing image.Alternatively, standard testing image can not also be obtained by really shooting, but according to survey
Examination constraint condition calculates standard testing image, obtains coordinate of the characteristic area in standard testing image.
203, whether within the allowable range to judge the deviation, if within the allowable range, thening follow the steps 204, if
Beyond allowed band, 205 are thened follow the steps.
204, coordinate of other each characteristic areas in the test image that camera to be measured is shot is calculated, in this implementation
In example, that is, determine coordinate of the characteristic area a2-a18 in test image C.Then step 206 is executed.
Calculating coordinate of the characteristic area a2-a18 in the test image C that camera to be measured is shot can be there are two types of mode：
One is special according to coordinate of the fisrt feature region a1 in the test image C that camera to be measured is shot and first
Positional relationship of the region a1 and other feature region a2-a18 in the test image C that camera to be measured is shot is levied, is determined other
Coordinate of the characteristic area a2-a18 in the test image C that camera to be measured is shot.It specifically can be with reference to shown in previous embodiment.
Another kind is the coordinate and the deviation according to other each characteristic area a2-a18 in standard testing image B,
Determine coordinate of the other feature region a2-a18 in the test image C that camera to be measured is shot.
205, it is unqualified for prompting camera to be measured.If the deviation exceeds allowed band, illustrate camera group to be measured
The error of dress is excessive, is substandard product, and it is unqualified for prompting camera to be measured.
206, the coordinate according to each characteristic area in the test image that camera to be measured is shot is clapped from camera to be measured
Each characteristic area is extracted in the test image taken the photograph, and generates test result.
The embodiment of the present invention uses and determines that test pattern is specifically sat calibration method and taken the photograph to make up according to test pattern feature
As head is taken pictures deviation caused by central region offset, saves and adjust camera by manual methods and take pictures central region, shorten
Testing time substantially increases testing efficiency.
