description The invention discloses a device and method for testing an image collection system of a line scanning camera. The device comprises a mechanical platform and a screw rod guide rail platform capable of moving on the mechanical platform. An object table is arranged on the screw rod guide rail platform and provided with a gradient reflector used as an image collection target, and a bright-field light source used as a lighting source and the line scanning camera used as an image collection device are arranged above the gradient reflector. An image is divided, an average grey degree curve of pixels on each line is calculated, curves with the grey degree gradually raising and fluctuating are obtained, and collection system assess parameters are obtained by fitting the grey degree curves. Compared with an existing testing method, assess of the image collection system of the line scanning camera can be obtained in a quantified mode, performance of the collection system can be quantified, and performance of the collect
