The invention discloses a detection device for a splicing effect of a panorama camera. The detection device comprises a casing, the outer sidewall of the casing is provided with a charging joint, the casing is internally provided with a separator plate, each of the top end of the separator plate and the bottom end of the inner wall of the casing is provided with two slide rails and a first motor, each first motor is positioned at one side of the corresponding slide rails, an output shaft of the first motor is provided with a spur gear, the top ends of the slide rails are provided first and second detection plates respectively, and the first detection plate is placed over the separator plate. According to the detection device, the first and second detection plates are arranged in the casing, a camera and a laser scanning device are used to carry out scanning detection on an original picture and a splicing picture on the first and second detection plates, color, position and shape change in spliced positions is detected, and a distortion value obtaining module and an effect value obtaining module of a circuit board obtain the splicing effect by comparison and sampling.
