Camera lens holds seat equipped with lens module, and the removable scale is made of lamp holder, slit casing and fluorescent tube, sets above the lamp holder
There is slit casing, is equipped with fluorescent tube in the slit casing, the imaging system is by two part groups of Image Acquisition box and display
At described image collecting cassette holds the lens module on seat with display and camera lens respectively and is electrically connected.
It is described can be manually rotated platform can 360 ° can be manually rotated, trimming precision can reach 0.05 ° or more, for measuring camera lens phase
Close the field of view angle in product water plane.
It is fixed lens external member that the camera lens, which holds seat, and being fixed on camera lens can be manually rotated on platform, and make the optical axis of camera lens with
It can be manually rotated platform table top keeping parallelism.
The lamp holder has the stability for keeping mobile scale, and guarantees that slit casing and lamp holder platform keep hanging down simultaneously
Directly.
The slit casing is homemade slit-type tooling, and the width of slit can be adjusted according to actual needs.
The fluorescent tube is the LED light of low-power, the reference target as test FOV.
The imaging system is to acquire complete field-of-view information by Image Acquisition box to be shown on display, thus in real time
Monitor the variation of packaged type scale position in visual field, the test judgement at auxiliary visual field angle.
The utility model is the utility model has the advantages that the key point of the utility model is to can be manually rotated the adjustment angle of platform and slit set
Pipe, can be manually rotated 0.05 ° of vernier angle precision of platform and is sufficient for error requirements；And slit casing is an adjustable slit width
Device, it is a piece of, bad judgement position that slit is too wide, and see, which is not a light,；Too narrow light is not strong, Wu Fafen
It distinguishes.The slit of the design selection has evaded this problem well.The utility model has inexpensive, easy to operate, high-precision
Feature is very suitable for the measurement of on-vehicle lens, full shot and mould group field angle, can be used for general lens module visual field
The measurement at angle.
