Problems solved by technology

[0002] At present, the penetration rate of smart phones is already very high, but the powerful potential functions of smart phones are far from being developed accordingly; the potential functions of other smart shooting devices, such as smart cameras and smart video cameras and electronic telescopes, are also not realized Corresponding development
The main force of the existing non-contact measurement is still the level instrument. However, in reality, the accuracy of most non-contact measurement does not require the high precision of the level instrument, and it is the measurement demand anytime and anywhere.
In addition, the existing commonly used tape measures are not only suitable for occasions where contact measurement is possible, but because they are not convenient to carry around, they still cannot meet the measurement needs anytime and anywhere

Embodiment 1

[0029] Embodiment 1, the universal shooting and measuring ruler of the present invention is that the shooting device is equipped with at least two laser heads in the same direction as the shooting lens through a plug-in plate, and the axes of the two parallel laser heads with a known distance are parallel to the shooting lens. The device shoots the measured object and two parallel laser spots projected on the measured object by two parallel parallel laser heads, and the shooting device or other image analysis equipment calculates the measured object based on the distance between the two parallel laser spots on the captured picture The geometry of the part being photographed. It can also be that the shooting device shoots the measured object and two parallel laser spots projected onto the measured object by two parallel laser heads and a third laser spot projected onto the measured object at a known inclination angle. The shooting device Or other image analysis equipment, based...

Embodiment 2

[0047] Embodiment two, such as figure 2 As shown, the difference between the present invention and Embodiment 1 is that the two parallel laser heads 4 are horizontal laser heads 4 arranged on both sides of the smart phone 1 camera 3, and the two beams of parallel parallel laser axes emitted by the left and right laser heads 4 are aligned with the cameras. 3 optical path axes are all on the same horizontal plane. The axis of the optical path of the camera 3 is parallel and equidistant from the axes of the two parallel laser beams.

Embodiment 3

[0048] Embodiment three, such as image 3 As shown, the difference between the present invention and the second embodiment is that the intelligent photographing device is an intelligent camera 10 .

Abstract

The invention relates to a universal shooting measurement rule. By the universal shooting measurement rule, the problem that an existing measurement device cannot be frequent to carry is solved. A shooting device is used for shooting a tested object and two parallel laser points, projected onto the tested object, of two parallel laser heads by additionally arranging an insertion plate of the shooting device and at least two laser heads in the same direction of a shooting lens, the shooting device or other image analysis equipment is used for calculating a geometric size of a shot part of the tested object by taking distance between the two parallel laser points on a shooting image as a reference, the shooting device is used for shooting the two parallel laser points, projected onto the tested object, of the tested object and the two parallel laser heads and a third laser point, projected onto the tested object, of a known dip angle, and the shooting device or other image analysis equipment is used for calculating distance between the geometric size of the shot part of the tested object and the lens by taking the distance between the two parallel laser points on the shooting image and a dip angle of the third laser point as reference. The universal shooting measurement rule has the advantages that the universal shooting measurement rule can be carried and demands of universal measurement accuracy and conventional measurement items are satisfied at any time and at any place.
