The related performance indicator requirement of head end video acquisition component, the mobile embedded testing vernier being embedded in measuring instrument, by preceding
It holds video acquisition component acquisition embedded testing vernier to show numerical imaging or video, figure minimum photographic distance, field angle is carried out with this
The performance indicator of degree and illumination zone detects.
Before being detected, further includes opening handheld video somascope according to products instruction, confirm hand-held
The step of video check instrument can work normally.
The process that this example carries out initialization detection device is as follows:
Firstly, by (i.e. in semicircle orifice 110), position is initially embedded in the normal direction groove for testing vernier insertion semi-circular plate measuring instrument
Setting should be at 1.0cm；
Then, vernier angle is tested in adjustment, and the inclination reflective mirror above exact p-value vernier directly displays on graduation mark
Distance values.
This example carry out related performance indicator test operation specifically includes the following steps:
(3.1) the minimum photographic distance index request of video acquisition front end assemblies is that somascope is being less than or is being waited apart from target subject
Target subject correlative detail should be able to be clearly apparent at 10mm.Thus, according to product service manual, test vernier is placed on band and is carved
It is moved on the normal direction groove of the measuring instrument of degree, is until video acquisition front end assemblies can be clearly apparent test vernier correlative detail
Only, the numerical value on the normal direction scale where record test vernier, and judge whether somascope meets the requirement of this performance indicator.
(3.2) the field of view angle index request of video acquisition front end assemblies is the visual field of somascope front-end video acquisition device
Angle should be greater than or be equal to 45.0 °.Thus, according to product service manual, mobile embedded test vernier, until display screen is shown
Until embedded testing vernier edge, the numerical value of the angle index at the place of embedded testing vernier is recorded.Pass through 3 times or 3 times
The above measurement is averaged, and judges whether somascope meets the requirement of this performance indicator.
(3.3) the illumination zone performance indicator of video acquisition front end assemblies is that the secondary light source illumination of somascope should meet two
Item requires, and first is that should cover video acquisition range, and second is appointing apart from light source 1.0m in field angle after secondary light source is opened
Intensity of illumination should all be more than or equal to 50lx at meaning.Thus, repeatedly the step of above-mentioned (3.2), open secondary light source illumination, check
Embedded testing vernier can determine whether somascope meets the first requirement of this performance indicator whether in illumination range.
In addition, the illumination of the secondary light source of somascope to be adjusted to most high-grade, illumination photometer of the service precision more than or equal to 0.1lx, respectively
By marking at normal distance light source 1.0m and on symmetrical measuring instrument at the rear view being selected on measuring instrument with a scale
It infuses and carries out intensity of illumination measurement at 1.0m, record the reading of illumination photometer respectively, be averaged, and judge whether somascope meets
The second of this performance indicator requires.
From the foregoing, it will be observed that this example, by using above-mentioned detection device, according to above-mentioned detection method, user be can be convenient precisely
Ground measures the performance indicators such as minimum photographic distance, field of view angle and the illumination zone of handheld video somascope, directly reads with specific
The measurement result that numerical approach embodies.
It can be seen that by using the detection device of clear scale value, the detection method of operating specification science can be realized effectively
The laboratory of handheld video somascope related performance indicators is precisely detected, and experimental condition controllability is high, and repeatability is strong, energy
Greatly improve detection efficiency.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
