Problems solved by technology

However, these methods have a large amount of computation, such as multiple frames and multiple exposures, which require multiple iterative processing of the image; or a large amount of data, such as requiring two or more exposures, the processing data is doubled, and multiple exposures will have a time difference , the measurement object cannot move; the dynamic range of multiple exposure images can only be increased to 120dB, which cannot completely solve the glare and other interference of the laser image

Embodiment 1

[0028] Embodiment 1: Assuming that the maximum dynamic range of the photoelectric imaging device that can receive light intensity is 0-2500, when the received light intensity range is 0-10000, the light intensity in the range of 1000-10000 is a saturation value, and at this time the electric The image presented by the imaging device is as Figure 7 As shown, the optical filter device can be used to increase the maximum dynamic range of the optoelectronic imaging device and present images with high dynamic range.

[0029] Such as Figure 5 with Image 6 As shown, five groups of optical filter stripe groups 2 are arranged on the glass substrate, and the total width W of the five groups of optical filter stripe groups 2 3 equal to the width W of the image sensor chip 4 4 , the height H of the optical filter stripe group 2 1 equal to the height H of the image sensor chip 4 2 . Each optical filter stripe group 2 includes a first optical filter stripe 31, a second optical filt...

Abstract

The invention discloses an optical filter device capable of widening the dynamic range of photoelectric imaging equipment. The optical filter device comprises a glass substrate, wherein at least one optical filter strip group is arranged on the glass substrate, the optical filter strip group comprises N optical filter strips with different cut-off rates (N is greater than or equal to 2), the cut-off rates comprise the maximum cut-off rate and the minimum cut-off rate, and the improvement multiple of the dynamic range of the photoelectric imaging equipment is determined by the maximum cut-off rate and the minimum cut-off rate. According to the optical filter device capable of widening the dynamic range of the photoelectric imaging equipment, the problem that the dynamic range of the photoelectric imaging equipment is insufficient can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of image dynamic range, in particular to an optical filter device for improving the dynamic range of photoelectric imaging equipment. Background technique [0002] Line-structured light measurement is to project a laser line onto the object through a laser projector. The photoelectric imaging device images the object with laser stripes. The light features on the image correspond to the light of the projector. According to the principle of triangulation, it can be determined that the object falls The depth information of the upper ray. [0003] Laser light has the characteristics of strong energy and good directionality, but at the intersection of different materials, such as metal and rubber sheet, the difference in reflection intensity can reach hundreds of times. For metal materials that have been processed by grinding, due to the different intensity of reflection in the area, very strong specular glare i...
