Description
Technical field:
The present invention relates to optical camera lens device, be applicable to safety-security areas such as square, bulk storage plant, market, airport, traffic administration, also can be used for video conference, plant produced line etc. need spend the occasion of carrying out timing monitoring and observation to circumference 360.
Prior art:
For overcome adopt many television cameras or with fire ball television camera that can 360 degree high speed rotating to circumference 360 degree carry out that comprehensive timing monitoring exists expensive, be difficult to defective such as in good time panorama sampling, the scheme with single bugeye lens video camera is assisted and computer image treatment is carried out pan-shot has been proposed.Existing technical scheme is that taken panoramic picture on CCD or CMOS picture pick-up device is carried out Flame Image Process by supporting computer software, is launched into the plane panoramic picture of undistorted (distortion obtains proofreading and correct) on display screen.For the convenience on the Flame Image Process, common optical technology is to make the light beam of a certain scope in dead ahead of camera lens in not imaging of imaging surface, promptly forms the circumference panorama pattern of " annular " of band " black Dapple " at the picture pick-up device center section.Existing way is to utilize coaxial double mirror can have the principle of blocking light action to realize forming the circumference panorama sketch of " annular " to the scenery in its dead ahead, but this way one-piece construction is big, principal reflection mirror adopts aspheric surface mostly, the dress school also is not easy, cost of manufacture is higher, another kind of way is to adopt the electronic technology method, by special dedicated video cameras such as electron scanning processing, make picture pick-up device form " black round class " position at needs and do not scan, can realize that also a bugeye lens panorama sketch changes the circumference panorama sketch of " annular " into.This method can not be widely used on the TV camera commonly used obviously.
Summary of the invention:
The objective of the invention is to overcome the deficiency of said method, by the super wide-angle of miniaturization of exploitation and built-in secondary light path, " black Dapple " on circumference panorama thing and the special graticule is incident upon simultaneously the surface of picture pick-up device, form the circumference panorama sketch of " annular ", easy to implement the method, camera lens adaptability is strong, cost performance height, miniaturization.
The present invention program: it is that main optical path and built-in secondary light path are formed that contrive equipment reaches 180 ° ultra wide-angle imaging camera lens by the visual field.
Main optical path is made up of ten lens.The optical material of ten lens is ZK in proper order

Setting the above-mentioned purpose that must satisfy is:
The purpose that condition (1) is set is that to guarantee that axle that basic wide-angle lens part is born is gone up total drift angle of light beam not too large, is beneficial to reduce the senior aberration of a last light beam and picture side's rear cut-off distance of growth main optical path.The angular magnification of bundle part is expanded in the visual field of also favourable minimizing simultaneously.
The setting of condition (2) is relevant with the basic wide-angle lens condition of preceding establishing, and the size that limits it helps the correction of off-axis aberration.
Aberration correction is perfect not to be set the purpose of condition (3) for balanced growth picture side intercept does not influence again.d
4Short, can increase picture side's intercept, but also increase the upward drift angle amount of light beam of axle relatively, be unfavorable for the correction of aberration; Otherwise effect is opposite.
The purpose that condition (4) is set is to make the light hurdle as far as possible near the front focus of the optics combination of a side behind the light hurdle, makes emergent pupil tend to the heart far away, and axle is gone up and the difference of outer illumination of axle and resolution distribution to reduce.
The purpose that condition (5) is set is spherochromatism and the outer ratio chromatism, of axle on the axis calibration.
The purpose that condition (6) is set is to guarantee that " black Dapple " on the graticule can accurately be imaged on the imaging surface of picture pick-up device.
The purpose that condition (7) is set be projection image for control " black Dapple " in panorama pattern magnitude proportion, be beneficial to reduce the ratio that light beam blocks light on the main optical path axle, also help the making of graticule " black Dapple ".
The principal character of apparatus of the present invention is: by built-in secondary light path " black Dapple " on the graticule is projected on the imaging surface, solve the requirement of circumference 360 degree panorama patterns " annular " changes that make picture pick-up device simply and effectively, made things convenient for computer image treatment software that panorama expanding is become undistorted plane circumference panorama sketch.Its introducing does not influence the design of main optical path optical texture, and aberration performance and outward appearance make main optical path optimal design separately.The bugeye lens that the visual field of the high resolving power that this programme is developed, high-performance, high performance-price ratio is 180 ° has adopted global face structure and cheap optical material.
Table 1 is main optical path embodiment data of the present invention.
