Abstract
(EN)
Provided are a positioning device for calibrating camera levelness and distance and a method thereof. The positioning device comprises a fixed frame (1) and a tripod (4) arranged opposite each other. The fixed frame (1) is provided with a photographic plane (2); a laser emitter (3) is vertically arranged on the photographic plane (2); a 360-degree rotatable clamp base is arranged on the tripod (4); the clamp base is used for mounting a camera (5), enabling the camera (5) and the laser emitter (3) to be linearly positioned on a same straight line, so that a transmitting beam of the laser emitter (3) coincides with a reflected beam of the lens of the camera (5); and a gauge (6) is arranged between the fixed frame (1) and the tripod (4). By means of the positioning device and the method thereof, camera levelness and distance between a camera and a photographic plane can be quickly calibrated.

La présente invention concerne un dispositif de positionnement pour étalonner un niveau et une distance de caméra et un procédé associé. Le dispositif de positionnement comprend un cadre fixe (1) et un trépied (4) disposés l'un en face de l'autre. Le cadre fixe (1) est pourvu d’un plan photographique (2) ; un émetteur laser (3) est agencé verticalement sur le plan photographique (2) ; une base de pince rotative à 360 degrés est agencée sur le trépied (4) ; la base de pince est utilisée pour monter une caméra (5), de façon à permettre que la caméra (5) et l'émetteur laser (3) soient positionnés linéairement sur une même ligne droite, de sorte qu'un faisceau de transmission de l'émetteur laser (3) coïncide avec un faisceau réfléchi de la lentille de la caméra (5); et une jauge (6) est agencée entre le cadre fixe (1) et le trépied (4). Au moyen du dispositif de positionnement et du procédé associé, le niveau de la caméra et la distance entre une caméra et un plan photographique peuvent être rapidement étalonnés.
